[[caption-width-right:232:"It's a secret to everybody."]]

->''"You are a stupid, square-headed bald git, aren't you? And you, I'm pointing at you, I'm pointing at you, but I'm not actually addressing you. I'm addressing the one prat in the whole country who's bothered to get hold of this recording, turn it 'round and actually work out the rubbish that I'm saying. What a poor, sad life he's got!"''
-->-- Backmasked message played in ''Series/RedDwarf'', "Backwards"

Originally, "Easter Eggs" was the term for little bits of stuff programmers left behind in the software. They're secrets, intended to tickle the fancy of those who discover them. Programs far too numerous to mention have included Easter eggs -- everything from Microsoft Office to ''VideoGame/GrandTheftAuto: [[VideoGame/GrandTheftAutoSanAndreas San Andreas]]''.

But Easter eggs aren't just found in software any more: the term is also used for a variety of hidden content, such as {{Hidden Track}}s on albums and unadvertised DVDBonusContent, and at one time, for people who sat through the credits (now referred to as {{The Stinger}}).

The first Easter eggs were inserted by programmers for companies whose policy forbade them from receiving individual credit for their work. The earliest Easter eggs were mostly credits pages, possibly to allow the programmers themselves to prove authorship to friends. For security reasons (and concerns about malicious programmers inserting undocumented and destructive code), most companies don't allow Easter eggs to appear in their software any more, but as individual programmers now receive full credit for their work, it's a moot point. [[labelnote:.]][[SelfDemonstratingArticle Congratulations! You found an easter egg on this page!]][[/labelnote]]

An article on why Easter eggs exist (focusing on ''TabletopGame/MagicTheGathering'', but applicable to all games) is available [[http://www.wizards.com/default.asp?x=mtgcom/daily/mr257 here]].

For time-sensitive Easter eggs, see HolidayMode. For in-story EasterEgg dates that reference original air/release dates, see SignificantReferenceDate.

Some Easter eggs can be found with a RocketJump or a well-timed DoubleJump. You can also find some if you use the bunny hop trick. [[labelnote:.]]See? Here's an example of one! Why did you click this anyway? Maybe you should look at the above quote...[[/labelnote]]

Subtropes include BilingualBonus (when the the audience member must know a language other than the main one of the work to get the extra information), FreezeFrameBonus (an Easter Egg that can only be found by stopping the playback of a video at the right time), subtle forms of Foreshadowing (for when you go back and discover that minor events or FreezeFrameBonus moments tie into events to come, rather than more explicit Foreshadowing) and WhatTheHellPlayer (an Easter Egg you get for doing something odd in a game).

For many, part of the fun of Easter Eggs is discovering them on one's own, so if you're one of those, beware of '''spoilers'''.

See also [[ShoutOut Shout Outs,]] which are basically Easter Eggs that are very easy to find.



[[folder:Video Games]]

* UrExample: The Fairchild Channel F console (released in 1976) came with a "Demo Cart", in which a key combination can bring the programmer's name, Michael Glass, up on screen. Both ''Alien Invasion'' and ''Video Whizball'' (1978) also have a code to display their programmer's last name (Reid-Selth, for Brad Reid-Selth) on the screen.


[[folder: Action-Adventure ]]

* TropeCodifier: The most famous early EasterEgg in a video game (to the extent where it's often [[OlderThanTheyThink mistakenly believed to be the first]]) is Warren Robinett's famous hidden signature room in the ''VideoGame/{{Adventure}}'' cartridge for the UsefulNotes/{{Atari 2600}}. By finding an item [[PixelHunt hidden deep in a maze of the same color]] and bringing it into the right room, one can move though a previously impenetrable barrier, where the text "Created by Warren Robinett" can be found. This was in an era when Atari refused to put the names of game creators on any of its game packaging, and it neatly takes up the leftover memory on the 4K ROM comprising the cartridge.\\\
An Atari executive coined the term when he compared finding the hidden room to "hunting for Easter eggs". While Atari hired a programmer to find where Robinett's name was in the code, they let it slide; Robinett later asked the programmer what he would have done if told to delete the code, and was told that he would have switched it to "Replaced by (programmer's name)".
* ''VideoGame/TheLegendOfZeldaALinkToThePast'' contains one of the most unusual Easter eggs in gaming history. ''Magazine/NintendoPower'' magazine held a contest and the winner, Chris Houlihan, had a [[ContestWinnerCameo secret room named in his honor]] placed in the game. [[http://zelda.wikia.com/wiki/Top_Secret_Room "The Chris Houlihan Room"]] is filled with Rupees (the monetary unit of the game) and a small plaque identifying it. Many players are still unaware of its existence, due to the difficulty it takes to get there: outside of cheating, it can only be accessed if the game fails to load an area and puts Link there as a failsafe.
%% because it's contested whether the Chris Houlihan Room is meant to be in the game at all. Evidently, not everyone at Nintendo was on board with the contest, so the room ended up getting added and removed multiple times as the game went back and forth between decision-makers who thought Chris ought to get his room, and those who thought the contest was bunk and shouldn't be honored. Leaving it in but buried so that it was inaccessible to anyone who wasn't cheating was evidently the compromise they came up with.
* ''VideoGame/LEGOAdaptationGame'' in general are filled with Easter Eggs, most of them necessary for OneHundredPercentCompletion.
** One of the doors in a hallway on Kamino in ''VideoGame/LegoStarWars'' leads to a room where there is a puzzle to be completed. If you solve the puzzle, the floor becomes a disco and a disco version of the ''Star Wars'' theme plays.
** The LEGO games ''VideoGame/LegoIndianaJones'' even has [[http://www.youtube.com/watch?v=6WI9NoKPWn4 several Star Wars characters hidden in various levels.]]
** A "disco" egg appears in pretty much every LEGO game in the series, with the music adjusted for the game's theme (a disco version of the ''Film/RaidersOfTheLostArk'' theme in ''LEGO Indiana Jones'', for example).
* The ''Batman Arkham'' series has a tradition of including Easter Eggs that foreshadow later games in the series...but are either hard to find or hard to decipher.
** ''VideoGame/BatmanArkhamAsylum'': One easter egg was so well-hidden that it wasn't discovered until the developers threw the fans a bone four months after its release and outright said "There is an easter egg nobody has found in this room of the game." In Warden Sharp's office in the mansion, placing multiple explosive gels on a wall will reveal a secret room with plans for [[VideoGame/BatmanArkhamCity Arkham City]].
*** Aaron Cash's employee ID # is 894390. This was taken directly from his initial appearance in ComicBook/ArkhamAsylumLivingHell where it is mentioned exactly once.
** ''VideoGame/BatmanArkhamCity'': If the player uses the radio frequency scanner, they can find three unregistered stations, all of which just consist of a voice reading off a string of numbers. After translating the codes (which requires various cyphers -- including two different ones for the last message), the player gets three threatening messages from Scarecrow, including "You will pay for what you did to me" and "Fear will tear Gotham to shreds", foreshadowing his role as the BigBad of ''[[VideoGame/BatmanArkhamKnight Arkham Knight]]''.
*** One-upping its predecessor, ''City'' had an Easter Egg with Calendar Man that went hidden for '''''over 3 years'''''. If you talk to him on the day that Rocksteady (the developer of the series) was founded, he has unique dialogue, including an important bit of foreshadowing: "I was there at the beginning, and I will be there at the end." [[spoiler:Indeed, Calendar Man can be seen in the crowd around Wayne Manor in the GoldenEnding of ''Arkham Knight''.]]
** ''VideoGame/BatmanArkhamKnight'': Interacting with the piano on the Wayne Manor challenge map (which was added in the last DLC) will open a hidden panel in the nearby wall, revealing a [[StringTheory diagram for an investigation]]. It turned out to be Batman's notes about the events of ''VideoGame/BatmanArkhamVR'', which was in development at the time.
* ''VideoGame/GrabbedByTheGhoulies'' contains ''tons'' of Easter eggs from the ''VideoGame/BanjoKazooie'' games, mostly in the form of paintings of the various ''Banjo'' characters placed around the mansion. There's also an infamous whiteboard in one room apparently listing part of a(n incomplete) solution for ''Banjo'''s [[UrbanLegendOfZelda "Stop 'n' Swop"]].
* In ''Film/XMenOriginsWolverine'' the video game:
** There's a section of the game where you can see [[VideoGame/WorldOfWarcraft Frostmourne]], the Lich King's sword, in a heap of ice rocks. Next to this is a skeleton with an exclamation point above it, referencing the marks for quests in ''World Of Warcraft''.
** There are two other easter eggs that reference ''VideoGame/{{Portal}}'' and ''Series/{{Lost}}''. You get achievements for finding each one.
* In ''VideoGame/AssassinsCreedII'', pull the lever and stare into the water in one of the Assassin Tomb dungeons long enough and [[spoiler:[[http://www.youtube.com/watch?v=nYDpSRONmFI a giant squid swims by.]]]] Hang around a little while longer and [[spoiler:''it attacks you!'']]
* ''Franchise/StarWars: Shadows of the Empire'' has a few of its own -- of note is the [[SamAndMax Max head]] challenge point in the Swoop bike level. Entering _credits as the name of your file will cause the game to play the credits instead of a selected level, and once the regular credits end, it starts spewing out Creator/MontyPython and cartoon references.
* The ''Starfighter'' series developers liked including these.
** In ''VideoGame/StarWarsStarfighter'', they hid a droid grilling hamburgers in the second mission.
** In ''VideoGame/JediStarfighter'', they hid ''literal'' Easter eggs and a droid building a snowman in the Mount Meraken mission.
* In ''VideoGame/ShovelKnight'', during Plague Knight's campaign, the final boss's first form is [[spoiler: a shadow clone of Plague Knight. There are two ways to end the fight and go to the second phase; either defeat the clone, or sit for 40 seconds without doing anything, which in turn causes you to take no damage. Doing the latter not only ends the first phase early, but it also nets this:]]
-->'''[[spoiler: Shadow Plague Knight (also known as ????)]]''': [[spoiler: You are steadfast in your resolve... Maybe there's hope for us yet...]]


[[folder: Adventure ]]

* In ''VideoGame/{{Myst}}'', Achenar's treehouse in Channelwood plays a series of recordings, which can also be accessed as video files on the game disc. Playing one of the videos backwards will reveal the message: "Creator/RushLimbaugh understands."
* ''VideoGame/RivenTheSequelToMyst'' had a series of "Spyder Eggs" riddles on [[http://cho.cyan.com/ its website]] (and those of the associated companies), leading to the discovery of the [[ArcNumber five]] Easter Eggs in that game. (By far the best is the one where the actor playing Gehn [[spoiler:bursts into song. He's actually quite good.]])
* ''VideoGame/MystIIIExile'' and ''VideoGame/MystOnline: Uru Live'' also have Easter eggs. Some re-releases of the original game Myst have Easter eggs as well, but these were added later and are not part of the original game as designed by the creators. A well-known Myst fan named Zardoz is responsible for cracking some of the tougher to find eggs.
** ''Uru'' has a secret egg quest which starts out in a room with a giant Easter egg floating in the center of it, and ends with you being allowed to [[spoiler:drive a Zamboni around outside the starting area]].
%% * The ''VideoGame/QuestForGlory'' series is one huge collection of Easter Eggs.
* Back in Creator/LucasArts[='s=] prime, they had Steve Purcell's ''SamAndMaxFreelancePolice'' as mascots. Max has appeared in some form or other in ''every single adventure game'' they ever made, usually as the design of a room, or as graffiti on a wall. Look for a oval with two rabbit ears on it -- that's Max. Dying also counts as an EasterEgg in [=LucasArts=] games because it is almost impossible to do.
* There's a number of [[EasterEgg Easter Eggs]] to be found in ''VideoGame/TheCurseOfMonkeyIsland'' too. To list but a few examples:
** Starting a new game on 25 December or 1 January will display a message upon starting.
** Talk to Palido (the sunbather guy on Puerto Pollo's beach) and ask him how long he's been there. He'll tell you he's been there since eight months before the current month on your computer calendar. If your computer calendar shows January, he'll wish you a happy new year.
** On Blood Island, go to the lake and try to pick up the water to make Guybrush remark "I don't really want to go in the ocean." Do it 25 times, and Guybrush will eventually go underwater -- and appear in the underwater scene from ''VideoGame/TheSecretOfMonkeyIsland'', complete with drowned Guybrush sprite (which is labelled as "fish food"). After Guybrush leaves, search the water and you can find an arrow that lets you go down and have a proper look round.
** In the Goodsoup Family Crypt on Blood Island, examine the hole in the back wall (where the roots are) to find yourself in the forest of Mêlée Island from the first game, complete with original music and [=HUD=]. Unlike the water scene, you don't get to have a proper look round, but it is a nice CallBack to the first game, where examining the stump (which Guybrush pops out of in this EasterEgg) reveals that it leads to "a system of catacombs" -- presumably the Goodsoup Family Crypt.
** On Skull Island, when talking to the bandits, ask "What about toys, got any toys?" and Guybrush will be given a [=LeChuck=] doll. In the final area of the game, try using the doll on [=LeChuck=].
** Examine the clock on Puerto Pollo and Guybrush will read out the time, right down to the second. The time is the same as your computer clock. The clock also chimes every half hour.
** Mess with the lights in the theatre and you can make them form the shape of Max.
** When looking into Mort's room in the Goodsoup Family Crypt, you can find a book called Zombies Ate My Neighbors, the name of another Creator/LucasArts game.
** In Blondebeard's restaurant there's a single table visible with an undead pirate sitting there, wearing a hat that's obscuring his face. If you prompt Guybrush to touch the guy, he shoves him to get his attention, causing him to collapse onto the table and his hat to fall off. The pirate is actually [[VideoGame/GrimFandango Manny Calavera]]. As a bonus, a button falls off his jacket onto the table that reads "Ask Me About Grim Fandango".
* The early Lucasarts games contain several references to (usually) their immediate predecessor
** [[ZakMcKrackenAndTheAlienMindbenders Zak McKracken]] has references to slimy meteors, an unuseable gas tank, and the protagonist having dated the DistressedDamsel from ''ManiacMansion''.
** ''VideoGame/IndianaJonesAndTheLastCrusade'' has the yellow shard and crayon map in the school and the book "Everything you wanted to know about Caponians and Skolarians" in the Venice library.
** ''VideoGame/TheSecretOfMonkeyIsland'' has numerous references to ''VideoGame/{{Loom}}'', including a pirate making a lengthy advertising shill on demand.
* In Creator/TelltaleGames' ''VideoGame/SamAndMaxFreelancePolice'' game ''Abraham Lincoln Must Die!'', Max becomes President and has the power to change the date. Try changing it to Easter and checking the golf hole. You find a nice {{lampshade|Hanging}} and an achievement for the 360 version.
* A lesser known Creator/{{Sierra}} game, ''VideoGame/{{Shivers}}'', involves the player traversing a deserted museum to capture elemental monsters that killed three people in the past. As the museum is dedicated to the "strange and unusual", and the player is constantly afraid of bumping into these monsters, it's surprising that the Easter eggs are the scariest parts of the game. There are funny eggs, but also disembodied shadows and glowing red eyes in cramped, dark spaces. Their appearances are randomised, and all the more pants-wetting.
* In ''VideoGame/KingsQuestIIRomancingTheThrone'':
** One egg involves a note pinned to the back of a tree where you wouldn't be expected to go to read a note, with an advertisement for ''[[VideoGame/KingsQuestIIIToHeirIsHuman King's Quest III]]'' and the then-new ''VideoGame/SpaceQuest'' series. In the 1985 release, the ad is for ''VideoGame/TheBlackCauldron''.
** Another involves the Batmobile occasionally coming out of Hagatha's cave instead of Hagatha. If you type in "LOOK BATMAN", the message responding to you will say, "He looks lost. I don't think he belongs in this game."
** [[http://www.youtube.com/watch?v=v5UwAuQu2Bk And then some depend on the player doing silly stuff.]] (see 1:42 into the video)
* In ''[[VideoGame/KingsQuestIIIToHeirIsHuman King's Quest III]]'', looking behind the tapestry outside Gwydion's bedroom reveals a message about ''[[VideoGame/KingsQuestIVThePerilsOfRosella King's Quest IV]]''.
* In ''[[VideoGame/KingsQuestIVThePerilsOfRosella King's Quest IV]]'', in the AGI version, typing "Beam Me Up, Scotty!" in a certain area sends Rosella to the DevelopersRoom.
* In ''VideoGame/KingsQuestVAbsenceMakesTheHeartGoYonder'', putting the cloak on the broken sled causes King Graham to appear in a boat on the snow. While in the boat, clicking on the sled with the cloak causes a sea monster to appear, and the message "For Lisa from 0." The sea monster pushes King Graham off of a cliff.
* This trope is a staple of the ''VideoGame/NancyDrew'' video game series, sometimes allowing the player to add actual Easter eggs to Nancy's inventory.
** Perhaps the most memorable is a phone number which, if dialed in-game during ''White Wolf of Icicle Creek'', gets Nancy harangued by a phone-in psychic who references every previous game in the series.
** One EasterEgg in ''Legend of the Crystal Skull'' can only be accessed by visiting the out-of-game [[ViralMarketing website]] of a character from a previous game.
* ''VideoGame/{{Discworld}}'' has a somewhat infamous one [[http://trueblueaussie.com/Discworld1EasterEgg.htm detailed here.]] Creator/EricIdle had jokingly recorded the line "I want to be the first person in a game to say fuck," and they had to put it ''somewhere'', didn't they?
* The ''Series/DoctorWho'' adventure game, "The Gunpowder Plot", has these innocuous facts about the level... But after reading them, you can [[spoiler:hear a [[HellIsThatNoise sinister clicking noise]], and when you turn back, you can see one of the Silents. Looking at the fact again will result in the Silent talking about the history of whatever you looked at, and then just disappear]].
* In ''VideoGame/SpaceQuestVIRogerWilcoInTheSpinalFrontier'', playing Stooge Fighter III on the programmers' birth dates, April 11th, January 3rd or December 29th, will change the names of the fighters Lar-Man, Coily Joe and Big Mo to Shockmeister, Conradinator, and Flash Lytton.


[[folder: Card Games ]]

* In ''Videogame/YuGiOhReshefOfDestruction'', by inputting [[http://www.youtube.com/watch?v=6n5qsVFF6jM a certain code at Grandpa's Shop]], [[spoiler: Reshef becomes [[VideoGame/GanbareGoemon Goemon Impact]]]].


[[folder: Eastern RPG ]]

* One of the longest-recurring Easter Eggs is found in the ''Franchise/{{Atelier}}'' series. In every game, examining any barrel will result in the protagonist simply saying "Barrel". This line is usually voiced, to boot. Some entries have barrels that have gameplay uses, so those won't trigger the line, and there are some games that have a longer line such as "It's a barrel!" or require you to progress in the game to unlock the Easter Egg. Regardless, this is always present in games within the series in some form, no matter what.
* ''VideoGame/{{Persona 3}}'' has some unusual Easter Eggs found when using a Game Shark or other devices. Most notably, it has [[MissionControl Mitsuru or Fuuka]] [[NoFourthWall scolding you for cheating]] -- using several differently lines, and fully voiced, to boot. This happens if you use a cheat device to enable usage of [[spoiler:the Universe Arcana Persona]] in normal gameplay specifically.
** Other Easter Eggs also exist -- once you have all the characters, try making a party of all girls (barring the MC, of course, unless you play the female protagonist in ''Portable''), a party of all guys (Junpei, Akihiko, and Ken or Akihiko, Shinjiro, and Ken are the only combinations that work), all second year students (Yukari, Junpei, and Aigis), or the original SEES members (Mitsuru, Akihiko, and Shinjiro) and talk to one of them in Tartarus -- the members will say something about the party. Another one happens if you equip Mara as your Persona and enter the Velvet Room.
* In ''VideoGame/{{Persona 4}} [[UpdatedRerelease Golden]]'', if you go to the T.V. Listings from midnight to 1 A.M., you'll see Teddie running around. Tapping on him brings you to a screen filled with static, and Teddie saying that he made his own Midnight Channel, just so the player can see him. You can tap on him to see how he reacts. Each time you catch Teddie, you can play for about a minute and a half, before he runs off, but you can go to Teddie's Midnight Channel as may times as you wish during the time allotted.
* The first four ''[[VideoGame/DotHackR1Games .hack]]'' games came with [=DVDs=] detailing what happened in the real world during the events of the game. Watching these with the subtitles on will reveal area keywords for the game where you can find rare items.
** On a related note are the DVD cases of ''Anime/DotHackSign''. The back covers of the boxes have several random words highlighted. These are keywords leading to special areas in the .hack games that deal with a character or event covered in SIGN. Not only that, but when the [=DVDs=] are stacked in order, they spell "LOGOUT". The .hack series is one where avid fans learn very quickly that NOTHING is insignificant...
* [[VideoGame/PokemonRedAndBlue The first-generation Pokémon games]] have a truck in the game which isn't even seen during normal gameplay. The truck is only accessible if you have the move Surf which is not available until much later in the game, and the area from where you can get to the truck is closed off after its role in the story is complete. The only ways to get to the truck are to either trade for a Pokémon that knows Cut in order to bypass getting the HM for Cut on the S.S. Anne, or to be defeated by a trainer and get instantly transported back to Vermilion from the S.S. Anne, so that you can leave the ship without triggering the cutscene where it sails away (which would render the area inaccessible) at the same time. Then, after getting Surf, you can get to the truck. The secrecy of this truck made it infamous, with many rumors circulating that [[OlympusMons Mew]] was under the truck, that there was a sidequest involving a set of keys the player can notice left at the Game Corner, etc. This truck is still present in the [[VideoGameRemake remake]], and is just as hard to get to. However, looking south of the truck this time gets you a Lava Cookie. The hard-to-get-to truck with no purpose now gives you an item. By giving it some significance, the developers are acknowledging the billion rumors surrounding the truck all those years ago.
** The first-generation Pokémon games have perhaps the most famous easter egg of all time: Originally, the Pokémon Mew was included as an easter egg by a programmer who slipped it into some left-over space on the cartridge at the last minute, with no legitimate way to obtain it in-game.
* ''[[VideoGame/LunarTheSilverStar Lunar: Silver Star Story Complete]]'' has a ''VideoGame/{{Warlords}}''-like mini-game hidden on its "Making Of..." disc, accessible via a hidden code.
* In ''VideoGame/TalesOfDestiny2'', usually Judas will "fail" his last hi-ougi, Gishouken (Holy Sword of Justice). However, play through the game twice and unlock extensions in the grade shop the third time around, and he'll gain a 20% chance to "succeed". When he succeeds, his mask shatters, revealing [[spoiler: Leon Magnus]], and he'll perform the last bit of the hi-ougi, turning it into Infernal Suffering, and play through the rest of the battle unmasked. There's also an increased chance for new end battle quotes from him if he delivers the last hit of the battle.
* In ''VideoGame/LastWord'', winning the HopelessBossFight against Chatters will lead to some humorous banter about how Whitty wasn't supposed to win. [[StoryOverwrite She then pretends she lost so the story can continue the way it's supposed to.]]
* On a NewGamePlus in ''VideoGame/AVeryLongRopeToTheTopOfTheSky'', the number of endings you've found will be added to Amos' rotation of statistics. If you get all 13, Amos will scream "Oh, God! It's the voices again!" and the developer will speak through him to provide congratulations and some hints on the {{Bonus Dungeon}}s.
* In the relatively obscure MSX version of ''VideoGame/DragonQuest II'', removing all of your female party member's equipment and returning to the castle where the game begins will cause the king to become shocked at her walking around nude and give her a Provocative Swimsuit to preserve her modesty, which you then see a picture of her wearing. (If this sounds familiar, it's because ''VideoGame/LaMulana'' directly homaged this scene by - ahem - [[FanDisservice "rewarding"]] players who complete the Hell Temple with a similar picture using its ''very male'' main character.)


[[folder: Edutainment Game ]]

* In many of the ''VideoGame/LivingBooks'' games, there would be at least one Easter Egg in each title.


[[folder: Fighting Game ]]

* The now-freeware DOS fighter ''VideoGame/XenophageAlienBloodsport'' [[http://www.youtube.com/watch?v=UZuCJgAOKKQ allows you to beat up]] Series/{{Barney|And Friends}} if you fiddle around with the config files. And yes, the game does mock you if you lose to him (which is pretty much impossible to do involuntarily).
* ''VideoGame/TheKingOfFighters'' is not above secret special moves and such (in fact, in Creator/{{SNK}}'s earliest fighting game offerings, all super moves initially went unpublished, and to this day they sometimes keep a tiny number of them initially secret), but on occasion they put in some just for fun. As Bao in ''[='99=]''-''2001'', for instance, [[spoiler:if you hold down and the opponent does nothing, he starts drawing stuff on the ground... then sits down looking bored, then sort of nods off. Aww]].
** K' [[spoiler:also drops his usual fighting stance, starts blinking his eyes slower and slower and falls asleep if you stand still long enough]].
* In ''VideoGame/SuperSmashBros Brawl'', try listening to [[http://www.youtube.com/watch?v=VAXbb8R11pc to the BGM for Peach's Final Smash in slow motion.]] [[spoiler:It's a sped-up version of the Sky Heaven theme in ''VideoGame/SuperMarioBros3''.]]
** Lightly tapping down on the directional pad while playing as Snake on [[VideoGame/MetalGearSolid Shadow Moses Island]] will bring up a codec conversation about a character he's fighting.
** Similar to Snake, the ''VideoGame/StarFox'' characters [[http://www.ssbwiki.com/Star_Fox_Smash_Taunt can do this at their home stages]] starting in ''Melee'', and in the fourth installment, Pit does it on [[VideoGame/KidIcarus Palutena's Temple]].
** Also, as an Easter Egg inside the Easter Egg, when Snake does this while fighting against Falco, Slippy from ''Star Fox'' appears on the codec instead of a character from the ''Metal Gear'' series, telling Snake that he hacked into the system.
* ''VideoGame/JoJosBizarreAdventureHeritageForTheFuture'':
** Normally, Young Joseph's taunt is his "Happy, joy-py, nice to meetcha-py!" line he said against Santana in Part 2. When up against Jotaro, Polnareff, Avdol or Kakyoin, however, he instead does his signature "Your next words will be..." line and imitates their catchphrase. (Jotaro - "Yare yare daze.", Avdol - "Tch tch tch!", Polnareff - "Butage te yaru!" and for Kakyoin, "Rero rero.")
** The Stone Mask briefly shows up when a Stand Crash occurs or when Shadow DIO connects his "WRYYYYY!" super.
** Everyone has a unique transformation when struck by Alessi's Stand moves. Most are turned into kids but others transform outright.
** One loading screen on the PSX version sneakily displays DIO's part 1 full name ("Dio Brando")
* ''VideoGame/JoJosBizarreAdventureAllStarBattle'' retains Part 2 Joseph's talent for anticipating what his opponent is about to say, having one line for every character.
--> '''Joseph''': "Your next words will be, 'WRYYYYYYYYYYYYYY'!"
--> '''Dio Brando (Part 3)''': "WRYYYYYYYYYYYYYY!...*gasp*"
* ''VideoGame/StreetFighterII: The World Warrior'': [[http://mugenguild.com/forum/topics/akira-nishitani-speaks-sf2-director-154210.0.html The red Hadouken]] that Ryu and Ken can rarely throw, originally thought to be a glitch, is in fact an intentional easter egg that the programmers put in.


[[folder: First Person Shooter ]]

* ''VideoGame/DukeNukem3D'' map makers also loved to sign their names, often creating whole rooms that can only be seen by entering the "show map" cheat. However, a few are signed in-game along with messages asking the player how they got to the location. Ironic, considering that two of the messages are easy to find with no cheats at all!
** The ''VideoGame/DukeNukem3D Plutonium Pak'' CD, which patches Registered v1.3D to v1.4 and adds a fourth episode, contains a CD audio track of the finished version of "Grab Bag", the game's title music. A little-known fact about the tune is that the UsefulNotes/{{MIDI}} version included in ''Duke Nukem 3D'' is actually incomplete. In response to increasing interest, on June 2, 2014, Lee Jackson [[http://leejacksonaudio.lbjackson.com/ released the complete MIDI]].
* The ''Franchise/{{Halo}}'' games have ''lots'' of these; the below entries are just the tip of the iceberg:
** Most notable are the skulls, first introduced in ''VideoGame/{{Halo 2}}'', which have effects in-game when activated.
** A number of games include hidden terminals/audio logs/etc. which contain additional and often substantial lore information.
** There's the secret "Siege of Madrigal" music from ''VideoGame/{{Myth}}'', which is heard as SourceMusic in hard-to-reach locations in every Creator/{{Bungie}}-made entry, and also appears as a stinger on the ''VideoGame/HaloCombatEvolved'' soundtrack CD, at the end of the last track[[note]]Bonus points: the original "Siege of Madrigal" sounds [[SuspiciouslySimilarSong VERY MUCH]] like the song "Here Comes the [[GeniusBonus Fl]][[StealthPun ood]]" by PeterGabriel[[/note]].
** Most of the Bungie games also have a hidden Grunt with special dialogue.
** In ''Combat Evolved''[='s=] "Pillar of Autumn", a developer left a surprise for his girlfriend in the room the Unkillable Marines come from. It was her name, Megg, written in human blood. Another Megg egg appears in ''Halo 2''; if you make it through "Cairo Station" on Legendary without losing your shields once, a sound clip will play in the final room that says: "Megg, please report to the red courtesy phone. Megg, to the red courtesy phone."
** The giant soccer ball in ''2''[='s=] "Metropolis". It shows up again in ''VideoGame/Halo5Guardians''[='s=] "Meridian Station".
** Several of the music pieces in ''2'' have [[SubliminalSeduction backmasked speech]] that sounds like the Gravemind.
** ''VideoGame/{{Halo 3}}'' has a goofy one on "The Covenant" which is just Microsoft Sam commenting on the game and its developers.
** ''3''[='s=] "Siera 117" has hidden cavemen figures with then-Creative Art Director Marcus Lehto's face on them. They appear again in the end of ''VideoGame/Halo3ODST''[='s=] epilogue cinematic if you push your right thumbstick to the left.
** ''VideoGame/HaloReach'' has the Club Errera (named after halo.bungie.org founder Claude Errera) in "New Alexandria" where, by hitting a switch on another building, you can hear "Never Surrender" from the ''VideoGame/{{Halo 2}}'' OST [[WhileRomeBurns while the city is burning]], as well as a techno remix of "Siege of Madrigal" after hitting the switch on the roof of the building.
** In ''Reach''[='s=] "Pillar of Autumn", if you hold the right analog stick to the right in the cutscene where a Pelican lands in the ''Autumn''[='s=] hanger bay, you'll see the Master Chief in a cryotube.
** If you played ''[[VideoGame/{{Halo 4}} Spartan Ops]]''[='s=] "All the Secrets" solo, you can find a group of Grunts dancing in a circle.
** Several chapters of ''Spartan Ops'' also have hidden radios that, when shot, will replace certain lines of key dialogue with humorous lines from the ''Machinima/RedVsBlue'' cast. In "Spartan Thorne", it'll even replace the normal Spartan Laser ordinance drops with Gravity Hammers marked as "Sports equipment" (since someone accidentally dropped their Grifball equipment).
** In ''VideoGame/Halo5Guardians'', several levels have REQ-exclusive weapons hidden in them. These [=REQs=] are more powerful versions of standard weapons (often with unique properties) that otherwise can only be found in Warzone multiplayer and custom games.
** ''Halo 5'' also has a rather strange one on the first level; if you light all seven hidden knives on fire, your weapons will be replaced with a Prophet's Bane energy sword and Plasma Pistol, you'll gain active camouflage, and you'll have to fight several additional Promethean Knights plus a giant-sized Warden Eternal.
* ''VideoGame/Left4Dead'' and [[VideoGame/Left4Dead2 its sequel]] have numerous Easter eggs in its graffiti, with [[ShoutOut Shout-Outs]] to internet culture, other games, Creator/StephenKing, and so on.
** One piece of graffiti from the second game reads as follows:
-->Out of film
-->No helicopter
-->Zombies are too fast
-->Not going to make it
-->[[VideoGame/DeadRising Frank West]]
** The community-made campaign for the sequel, Suicide Blitz 2, while fan-made, deserves special mention due to having an amazing and well hidden Easter Egg. There's a garden gnome in the first leg of the mission, holding it prevents you from using any weapons or items and using it for melee attacks does partial damage. If you carry it to the last leg of the mission, you can place it in an alcove in an out-of-the-way room to gain access to an [[VideoGame/{{Portal2}} Aperture Laboratories testing facility]].
* Many of the older ''VideoGame/{{Counter-Strike}}'' maps featured credit sections or rooms. Notable examples are rooms in Aztec and Italy, and a breakable section of wall in Office. These have since been removed.
* The final boss of ''VideoGame/{{Doom}} 2'' is an Easter Egg. You're forced to shoot rockets into the exposed brain of a demon's head which takes up most of the wall. [[spoiler:If you cheat through, you can see that the demon's brain is designer John Romero's head on a pike. And the demonic-sounding sound file at the beginning is just the phrase "To win the game, you must kill me, John Romero" played backwards.]]
* ''VideoGame/ChexQuest'', a non-violent ''VideoGame/{{Doom}}'' clone, has a secret room in the third stage accessible only by [[spoiler:jumping from a rising elevator platform]]. Inside the room are [[spoiler:framed pictures of the programmers and the BFG-reskin]].
* In a women's locker room in ''VideoGame/{{Geist}}'', there are a few lockers that can be opened to reveal a Gamecube and Samus' suit.
* The ''VideoGame/{{Marathon}}'' series is infamous for hiding terminals in out of the way places, but they sometimes used them to hide "credit terminals" towards the end of the game. ''Marathon Infinity'' takes this one step further, hiding an entire multiplayer map (that was used to make screenshots for terminal pictures that showed up elsewhere in the game), in hex format, in two terminals: one in the first level, and one in the final level. The trick was turning this hex code into plain text. From there, a couple runs of the text (in a text file) though Stuffit Expander would result in the final, usable level. Full details can be found [[http://marathon.bungie.org/story/hangar96.html here]].
%% Greetings. You're asking yourself: Is this a trap or just a dead end?
* A literal case in the co-op mode of ''VideoGame/{{Resistance}} 2''; there is a broken bridge in Chicago's Garfield Park that, when you stand on the edge of it and look down, you see a nice blue and purple easter egg.
* In one of the ''Day of Defeat'' maps, Axis, [[http://www.youtube.com/watch?v=RBpHPL8-ins one can get]] (with some risk) hidden [[RareGuns FG-42]] (a paratrooper weapon unavailable on normal maps).
* ''VideoGame/PathwaysIntoDarkness'' has an actual easter egg hidden behind a fake wall on the level "Happy Happy, Carnage Carnage".
* The ''VideoGame/{{Quake}}'' games have Easter eggs hidden in certain levels. ''Quake'' and ''VideoGame/QuakeII'' have the [[VideoGame/CommanderKeen Dopefish]] in hidden areas. ''Quake II'' also has a rubber ducky in a secret level (which appears on a wall after riding a cycling elevator a certain number of times), a hidden area in the enemy base level where you can find and get John Carmack's head, and in the final level a hidden credits section along with a rather raunchy scene involving a few of the enemy units. Finally, ''VideoGame/QuakeIIIArena'' has the Dust Puppy underneath one of the maps (i.e. you have to fall off it to see it).
* In ''VideoGame/MedalOfHonor: Frontline'', as you are boarding Sturmgeist's train, a UFO flies overhead.
* In ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.]]: Perseus Mandate'', you can [[http://www.youtube.com/watch?v=lVaTWCrT3mU jump off from an elevator]] with godmode enabled and see the message "I suck at making maps" written on the wall at the bottom of the pit.
** In one specific room in the previous expansion, ''Extraction Point'', you can [[http://www.youtube.com/watch?v=jZI29EpPsTI&t=1m26s shoot an air vent cover]] to reveal a secret room with Norton Mapes dancing to the ''VideoGame/ShogoMobileArmorDivision'' theme. [[TakeThatScrappy And you can finally punch him in the face.]]
* Apogee's ''VideoGame/RiseOfTheTriad'' had a very silly egg added to a certain bug in the game. If a pushwall isn't properly defined, and escapes the boundaries of the map, the game will crash -- and [[http://www.eeggs.com/items/8590.html display a sketch of the wall]] ''smiling'' as it flees into space. This can be activated intentionally on a hidden level, appropriately named "This Causes An Error".
* One of the many, many achievement farming maps in ''VideoGame/TeamFortress2'' has several of these, down, but not limited to:
** A Pyro performing a JumpScare in an airvent.
** Being able to get out of the area you're fighting in.
** Finding Machinima/PainisCupcake himself.
** [[NinjaPirateZombieRobot A giant invincible cardboard cat head cutout]] [[https://www.youtube.com/watch?v=vb_9vxXyqdU shoots lasers and bees at everything before whiting out the screen, ending the match.]]
** A long invisible walkway outside of the map that takes you into a glass box above the fighting area, filled with sandviches, a pool, and Saxton Hale himself.


[[folder: Interactive Fiction ]]

* "XYZZY" has been a secret command or veiled reference in hundreds of programs (games and otherwise) over the decades since ''VideoGame/ColossalCave'' first appeared. The recent InteractiveFiction offerings (created by the fandom) often have some kind of response to the command.
** Easter Eggs in a (more recent) work of InteractiveFiction are often hinted at by the author after the game ends.
* Trying to scream or cry in ''Videogame/{{Anchorhead}}'' will yield different results depending on which stage of the plot you're in.
* ''VideoGame/EmilyIsAway'' has several hidden user icons that are unlocked by inputting specific usernames at the beginning of the game. Emily's dialogue at the start changes based on what icon you have; she'll make references to popular video games, music groups, memes, and even concepts and websites that don't exist in 2002, such as YouTube or Let's Plays.


[[folder: MMORPG ]]

* The redesign of the Faultline zone in Issue 8 of ''VideoGame/CityOfHeroes'' inlcudes a well-hidden "lounge room"; entering earns you the "Egg Hunter" exploration badge. Of course, the problem with that is that unlike the Warhammer example below, it's fairly easy to find, so about 5 seconds after the first hunter found it, everyone knew about it.
* ''VideoGame/WarhammerOnline'' has an Easter egg ''zone'' -- a player in the Inevitable City who manages to successfully navigate a battle-filled arena and do some careful jumping across a series of floating rock islands can find a Chaos gateway. Jumping through it lands one in an area identified by the loading screen as the Winds of Chaos, which consists of a random location filled with eye-candy. Possibilities include an icy crater filled with frozen daemons and one very cold high elf, a beautiful elven beach, a bird's nest on a mountain next to fleets of ships hanging in the sky, the moon, and the starting village from Mythic's ''Dark Age Of Camelot''. Sadly, you only remain in these areas for a few seconds before being teleported back to the Chaos capital, allowing only brief exploration.
* ''VideoGame/KingdomOfLoathing'' is full of Easter eggs and other stuff for MMORPG explorers (or "spades") to discover, including a literal one: during the final quest in the main game, you pass through one part of the Naughty Sorceress's tower by using a set of special keys on a Strange Door. If you use a [[{{Pun}} balloon monkey]] on the Door, it opens to reveal Unexplained Jamaican Man, who gives you an Easter egg balloon with the line "How about a [[HurricaneOfPuns balloon, mon]]?"


[[folder: Platform Game ]]

* In ''VideoGame/SuperMarioWorld'', when you stay on the map of the "special" zone (on "Star Road") for a couple of minutes, it starts playing a steeldrum version of the classic ''VideoGame/SuperMarioBros'' theme.
** Similarly, in the first ''{{VideoGame/Paper Mario|64}}'', if you left the controller idle on the Chapter start screen (e.g. the ones that displayed the Chapter's title), the original version of the ''Super Mario Bros.'' theme would play.
** A more [[ParanoiaFuel disturbing]] Easter egg can be found in ''VideoGame/SuperMarioGalaxy2''. Go to the Shiverburn galaxy, from the start go to the left, enter first person, and look up. You will see three shadowy figures with big eyes (?) looking at you from the cliff. And if you move to the next part of the galaxy, ''[[OffscreenTeleportation they will still be in front of you]]''.
*** Apparently, [[http://gonintendo.com/viewstory.php?id=126769 the game calls them "trees."]] Still quite disturbing, even knowing that.
** ''VideoGame/NewSuperLuigiU'' has a hidden Luigi in every level, some more obvious than others. Also, [[spoiler:it is possible to play as Nabbit by holding down a button while selecting a stage. Doing this on "Flying Squirrel Ovation", a level near the end of the game, allows you to play as a Mii.]] Similarly, there's a Luigi sprite in nearly every world map and every level in ''VideoGame/SuperMario3DWorld'' and each one has specific conditions that have to be met before you can find them.
** ''VideoGame/SuperMarioMaker'' is chock full of easter eggs, starting with the title screen--and many of them are based on ''VideoGame/MarioPaint'' (yes, the fly swatter minigame is in this game too). It is very worth your time to find these, as many of them will give you additional costumes (the previously mentioned fly swatter minigame gives you Builder Mario, for example).
* ''VideoGame/SonicCD'' has a secret passage in the Past and BadFuture versions of Wacky Workbench Act 1. In the Past, a green statue of an angel will be waiting for you and gives you a good amount of rings. However, in the BadFuture, [[OurFounder a gold statue of Eggman will appear instead]]. You can destroy it, but bombs will rain on you seconds later.
** Also from Sonic CD, if you input certain codes into the sound test, you can get several pictures, such as Tails in front of a car saying "See you [[VideoGame/SonicDrift next game!]]", Sonic, Metal Sonic and Robotnik in a band, and the infamous "Fun is infinite" message.
** The Blue Sphere game in ''VideoGame/Sonic3AndKnuckles'' also counts. Trying to lock a cartridge that isn't either Sonic 3 or Sonic 2 onto Sonic and Knuckles will give the message "No way? No way!" Press a certain button combination and you'll start one of the Blue Sphere minigames.
* ''VideoGame/MetroidFusion'' is more linear than most games in the series, but it still rewards would-be [[SequenceBreaking sequence breakers]] with an Easter egg -- a short cutscene which hints at the game's big [[TheReveal Reveal]] and ends with one character musing "I wonder how many players will see this message??" The answer is very few -- legitimately, anyway. The sequence break is [[http://www.metroid2002.com/fusion/other_secret_message.php incredibly difficult]] and accomplishing it is a badge of honour among ''{{Metroid}}'' fans.
* ''[[VideoGame/{{Pitfall}} Pitfall II: Lost Caverns]]'' for the Creator/{{Atari}} 8-bit and 5200 has an entirely new level after you beat the game that is ''longer than the actual game itself.'' This may be the largest relative Easter egg in any game.
* Later games in the ''VideoGame/JakAndDaxter'' series scattered (coincidentally egg-shaped) Precursor Orbs around the levels for players to find, which could be spent on various cheats and Easter eggs (found under Cheats in the pause menu), ranging from {{game breaker}}s such as infinite ammunition and invulnerability to more trivial stuff like mirroring the game world and toggling the protagonist's goatee on and off. The in-world explanation is that since the game takes place in the future, the formerly abundant Orbs have now become increasingly rare, and extremely valuable in the process.
** One mission in Jak 2 involves Jak fighting Krimzon Guards who launch explosives out of their blasters. If you look closely, the projectiles look just like the precursor explosive that knocked Daxter into the pool of dark eco in the first game.
* If you manage to get your hands on a copy of ''VideoGame/CastlevaniaSymphonyOfTheNight'', you can put it into a CD player and set it to track 2 to get a cool remix of one of the game's main themes. Topping it off are the opening moments of it, when [[spoiler:Alucard says "As you can see, this is a UsefulNotes/PlayStation black disk. Cut number one contains computer data, so please, don't play it. [[SchmuckBait But you probably won't listen to me anyway, will you?]]" He's being honest; nothing is there to listen to.]]
** Symphony of the Night in general has shitloads of easter eggs. Like the fountain in Olrox's quarters, which turns red for no reason, the birds nesting in one room, the random little upside down things in the first castle, the rare alternate form when Alucard gets turned to stone...
** The PCEngine version of ''[[VideoGame/CastlevaniaRondoOfBlood Rondo of Blood]]'' has two classic Easter eggs. The first one, like the above, requires you to play it in the CD player (which will play the game's soundtrack if you skip the non-music tracks), which starts up something like a miniature DramaCD track explaining that you can't play the game in a CD player, ending with Richter exclaiming "By the way, turn the volume down," which was shortly followed by ''massive screeching'' as the CD player tries to play the game's data and programming tracks. The second shows up if you play the game with a version 1 system card instead of the required version 2 card; you play a game that is an absolute mockery of a game, with horrifyingly cutesy renditions of Richter and Maria. The name of the level is "Stage X -- The System Card 1 Level."
* In the DOS platformer ''VideoGame/StixWorld'', BottomlessPits are usually marked with a "Danger!" sign. However, if you fall past a certain one that says, "Banger!" instead of "Danger!" while possessing a blue key, you can find a room with a giant actual easter egg. Collecting this egg causes a message to pop up informing you to "check in the game directory." Doing so reveals a rather bizarre easter egg: a text file containing the entirety of ''Literature/AliceInWonderland''!
* The Insomniac Museum of ''VideoGame/RatchetAndClank'' fame. It's an easter egg level full of stuff that didn't make it into the game in the style of the actual Insomniac Games office layout, and various Insomniac staff members have commentary on each item. The Museum appears in only three of the games, and is located on 'Planet Burbank' (in reference to where the company is located), or on 'Dantopia'. Getting into it usually happens by chance, since the rather out-of-the-way telepads that send you there only work when your [=PS2=] internal clock is set to the top of a specific hour. In ''Going Commando'', there's a second way to get in that doesn't require setting your clock, but is much more difficult to discover, since you have to do a series of very specific things most people would never consider doing otherwise.
%% * The secret stars in ''VideoGame/{{Braid}}''.

* If you hold B while selecting Shade Man's stage in ''VideoGame/MegaMan7'', the intro fanfare and BGM change to that of ''[[VideoGame/GhostsNGoblins Super Ghouls 'n Ghosts]]''' first stage.
** Capcom [[WordOfGod insists]] that VideoGame/MegaMan9 has an [[UrbanLegendOfZelda unfound secret]], but none of the many references, secrets, and little touches found by the players seem to be it.
** ''VideoGame/MegaManX1'' and ''VideoGame/MegaManX2'' give you the Hadoken and Shoryuken, respectively.
* The [=128K=] version of the UsefulNotes/ZXSpectrum game ''Zub'' has the hidden game ''Lightfarce'', supposedly by Fast-As-You-Like Software (a parody of FTL's ''Lightforce'') as an easter egg. It later saw release as a separate game (''Zarjas'').
* The Spectrum game ''Booty'', if loaded with a Currah [=MicroSpeech=] unit attached, comes up as a diving game.
* The first Alpha build of ''VideoGame/AHatInTime'' contains one not in the final build. In the first area, Mafia Town, there are several small islands ringing the level that you're not supposed to be able to reach due to the aggressive BorderPatrol. However, if you manage to make it past the shark, you can find a tent on one of the islands with a chalkboard inside with a hidden message: [[spoiler: "You're not supposed to be here! >:( Go away, or I'll send Queen Vanessa on you!"]] There's also a small monolith which contains ''another'' hidden message, this time in a cryptogram, and a special rainbow rocket with lots of fuel that you can use to explore the level and [[ScriptBreaking get to even more places you shouldn't.]]
* In ''VideoGame/{{Something}} Else'', there is a platform beyond the pipe at the start of "Darkave". It can only be accessed through clever use of the Athletic Peach, and features a mid-level gate and a pipe that leads to what is perhaps the best OverlyLongGag in any video game:
** The first room is a replica of a test level in the original ''Super Mario World'': a short room, without any background music, full of yellow blocks spelling out the word "TEST" (with an added invisible wall below the T; you need the Athletic Peach to wall-jump onto the blocks and bypass it) and a downward-pointing arrow. However, instead of a bottomless pit, there is a hidden pipe right below the arrow, leading to the next room. The bottom of the screen is an invisible floor.
** The second room is a raised platform, where 90% of it is covered in ramps that produce a hilariously glitchy effect when you run across them. Once again, the bottom of the screen is a floor (in case you fall off), and green apples rain down like confetti. There is a coin formation in an unknown shape at the end, and several doors throughout the level. Only the last one leads to the next room. [[BrokenRecord The music here is just a steel drum playing one note every two seconds.]]
** [[CutAndPasteEnvironments The third room is a carbon-copy of the second one,]] but the coin formation is replaced with a door leading to the final room.
** The fourth and final room features Luigi chasing a 3-Up Moon across a flat span of land, until a 1-Up Mushroom is generated. At this point, Luigi can touch the 3-Up Moon to exit the room.
** After venturing through this incredible, pythonesque series of rooms, Luigi just gets dropped back at the pipe he was supposed to go down to properly continue the level, with a refilled time limit.
* Xland Software's ''VideoGame/ElectroMan'' has two on Level 6:
** A dead-end room (no, not in the trope sense) has a distinctive pattern of tiles on the wall. Blast them away and a map of the level will be revealed.
** The room below this one has a set of pipes forming a swastika (the peace version, not the Nazi version).
* All three episodes of ''VideoGame/DukeNukem 1'', as well as the standard 10 levels, have a secret 11th level (the same one in all three cases; similar to, though not identical to, Episode 2 Level 1) which can only be reached by using the level-warp cheat. Of course, [[DeadEndRoom the exit leads only back into the same level, and the items (including the exit and some of the backgrounds) disappear]].


[[folder: Puzzle Game ]]

* ''VideoGame/{{Antichamber}}'': There are several DevelopersRoom[=s=] that showcase concept art, historical screenshots, and even a piece of shader code (coded with the Unreal Engine graphical editing tools). These tend to be well hidden behind the hardest puzzles in the game.
* ''VideoGame/TheTalosPrinciple'' is chock-full of easter eggs, enough to warrant [[http://steamcommunity.com/sharedfiles/filedetails/?id=355489493 a walkthrough]] dedicated to them. It would be easier to list which areas ''don't'' have any hidden easter eggs in them. There's even a few ''literal'' ones. The ''Road to Gehenna'' DLC, while shorter than the main campaign, [[http://steamcommunity.com/sharedfiles/filedetails/?id=487415447 isn't devoid of easter eggs]].
* ''VideoGame/TheWitness'':
** The sand castle from the cover of ''{{VideoGame/Braid}}'' is found in the sand pits of a glass blowing workshop.
** Several tableaux appear throughout the game and require the player to stand in a specific position in order to see them.


[[folder: Racing ]]

* ''VideoGame/WaveRace Blue Storm'' has an easter egg that went undiscovered for over seven years since the game's release. By inputting a button code at the game's audio menu, you change the voices of the [[AnnoyingVideoGameHelper coaches]] to ones that are [[DeadpanSnarker extremely insulting and berating no matter how good or bad you do in a race]].
* You may be familiar with [[HoodOrnamentHottie Reiko Nagase,]] the mascot for the ''VideoGame/RidgeRacer'' series. Well, in ''Type 4'', play as PRC and win every race. Around the time she appears in person she sends you a text message.
* ''VideoGame/GranTurismo'':
** If you manage to flip the premium Mine's R34 GT-R in the [=PS3=]-era games, you will notice "Thanks for finding this! :)" in the car's underside. The text [[http://www.gtplanet.net/gt5-easter-egg-r34-skyline-has-die-cast-underside/ originally]] mentioned [=AUTOart=] and the respective car model, as well its scale.
** Some of the fictional racing cars have the developers' names hidden in it. For example, the Pagani Zonda LM Race Car has the names of Takahito Tejima and Yuji Yasuhara (with Italian flag), the data optimizer and GUI programmer, respectively, of the third game. Meanwhile, zooming further the Ford GT LM Race Car Spec II (introduced in ''4'') reveals the names of real-life drivers Klaus Ludwig and Ricardo Zonta, the drivers of the Mercedes CLK-GTR that won FIA GT in 1998.
** The logo of ''Omega Boost'', Polyphony Digital's {{mecha}} game (and their only non-racing game so far), can be seen in the side in the Mitsubishi FTO Super Touring Car.
* In ''VideoGame/MarioKart 64'', after winning a race, if you let the music loop 64 times (which is nearly an hour!), the music will change.


[[folder: Real-Time Strategy ]]

* Creator/BlizzardEntertainment's games are rife with various Easter eggs. In the RTS games, clicking on a unit often enough results in them [[StopPokingMe uttering various funny lines]] (or, if it's a critter, they explode), and exploring the map in great detail may result in finding Easter egg units. For instance, zerglings, hydralisks, and marines from ''VideoGame/{{Starcraft}}'' can be found in ''VideoGame/WarcraftIII''. And let's not get started on ''VideoGame/WorldOfWarcraft''...
** In addition, with the exception of the first ''VideoGame/WarcraftOrcsAndHumans'', every Blizzard RTS (usually the expansion packs) to date has had a hidden music track. ''VideoGame/WarcraftII: Beyond the Dark Portal'' has "I'm a Medieval Man" (a reference to the song ''"Mechanical Man"'' in Command & Conquer), earned by typing the message "disco" or putting the game disc into a CD player. Typing "Medieval Man" in ''VideoGame/WarcraftII'' (Battle.net Edition) also yields this music. ''VideoGame/{{Starcraft}}: Brood War'' has Radio Free Zerg, a semi-subliminal StupidStatementDanceMix featuring the Overmind, earned, of course, by typing "Radio Free Zerg" while playing Zerg. Finally, ''VideoGame/WarcraftIII: The Frozen Throne'' has "Power of the Horde" by either typing in "Tenth Level Tauren Chieftain" or by beating the campaign (which accompanies the song with a nice in-game-engine music video).
** ''VideoGame/StarCraftII'' has the usual crossovers between Blizzard games (Tauren and Murloc marines, for example), but in the ''Wings of Liberty'' secret mission, there is a VideoGame/{{Metroid}} in a holding tank.
* The first ''[[VideoGame/CommandAndConquerTiberianDawn Command & Conquer]]'' has a hidden 5-mission mini-campaign hidden inside the game. The missions revolve around dinosaurs, and are Westwood's little tribute to ''Franchise/JurassicPark''. The missions and dinosaur graphics themselves were found pretty quickly when people started taking apart the game files, but due to some special programming that makes the dinosaur graphics invisible, they cannot be played as they were intended unless the actual unlocking code is used. This code turned out to be a command line parameter, namely ''funpark''.
** The game also has a set of hidden options that can be put in its .ini configuration file, which will unlock beta behaviour like undeploying the MCV, making wheeled vehicles actually manoeuvre to turn around, unlocking 6-player multiplayer mode, disabling the concrete padding added to the structures, and a lot more. One of the more notable ones is an option to unlock remixed music. This music had long been found in the game files, but before the existence of these options was revealed through hacking, no one knew there was a legitimate way to enable it. Since the words to be given to these .ini options are encoded to a 4-byte value with a one-way encryption algorithm (just like the ''funpark'' one), several of them were never found. The one used to unlock the hidden music (an option called "scores") was revealed, through brute-force algorithm cracking, to be "remix". However, due to the way the algorithm works, different strings can result in the same correct value. None of the other words found this way look like actual words, so the actual intended passwords for the other options remain a mystery.
*** Frank Klepacki, the composer, said in a later interview that the remixes are in fact the original versions, but they were deemed too "distracting" due to the voice clips they contained, and "clean" versions were made instead. Oddly enough, most console versions of the game do feature these enhanced versions.
** The UsefulNotes/{{Nintendo 64}} version of the game has a lot of funny lines in the skippable intro. One of them, ''"Clan Warsong is da bom"'', is an obvious reference to ''VideoGame/{{Warcraft}} II''.
* ''VideoGame/CommandAndConquerRedAlert'', like the first game, contains a secret mini-campaign involving giant ants. This one is an obvious reference to the nuclear mutants B-movies of the 50's and 60's, more specifically the movie ''Film/{{Them}}''. This Easter egg is already somewhat announced in Morse code innocently hidden in the manual as page decoration. Later interviews revealed that the developers put the Morse code in there without permission, in hopes of getting the producers to allow them to make the Easter egg, a sneaky move which turned out to be successful after the company got hundreds of letters from fans asking about it. Unlike the missions hidden in ''C&C''1, this one was completely added in the Counterstrike expansion, so no files were found in advance. The expansion pack box came with a small paper of Morse code with a pretty straightforward set of instructions (but no further explanation), which turned out to be for unlocking the campaign.
** Both ''Red Alert 1'' and ''Command & Conquer 1'' contain a hidden option to enable showing actual names for all neutral people and buildings, which normally only show "civilian" and "civilian building" as names. When enabled, each of these civilians will show the first name of one of the people on the Westwood team.
* ''[[VideoGame/CommandAndConquerTiberianSun Tiberian Sun]]'' has one in [[spoiler:the last Nod mission]]: there is a civilian building called the "Xmas Tree Farm", which itself is already pretty funny. Destroying it causes [[spoiler:CABAL]] to exclaim "SCROOGE!" at the top of the screen. It also yields a money crate for the effort.
* ''Videogame/StarWarsGalacticBattlegrounds'' has several Easter egg characters hidden in the corners of maps, such as Mara Jade. There are also cheats that will give you absurdly overpowered joke super-units such as the Death Star, a Star Destroyer, and [[KillerRabbit Simon the Killer Ewok]].
** The Star Destroyers were interestingly left out of the game entirely, despite being featured prominently in briefings. Eventually, the expansion introduced Air Cruisers that are pretty much the same as the Easter Egg Star Destroyer, but even with the lack of scale, they arevisibly designed to look smaller.
** One of the Wookiee missions has a fairly elaborate one. If you get up to Tech Level 3 and send a fighter to the right location, or just use cheats to dispel FogOfWar and then call upon the power that is Simon the Killer Ewok, you'll find an area containing sand dunes and Tatooine buildings, and the mission objectives will change to defending Queen Amidala from Tusken Raiders.
* In ''VideoGame/EuropaUniversalis 3'', Aragon has the mission to become King of Gonder, a province in Ethiopia. And to defeat Saruhan, a Turkish state that can sometimes appear as a revolter.
* ''VideoGame/CrusaderKingsII'': If you're besieging a holding in Tuscany and have siege events set to provide a pop-up instead of simply a sidebar message (the default setting), you might get a message that [[Film/ANewHope Tuscan Raiders]] have attacked your siege camps (instead of merely "brigands" as is usual).
-->'''PlayerCharacter:''' They will be back in greater numbers...


[[folder: Shoot Em Up ]]

* Steve Kitchen, the programmer of the Atari 2600 version of the arcade game ''VideoGame/{{Carnival}}'', had his name appear where the score is by hitting a special target that appears in the game if you hold down the action button to start the game just as you turn on the system.

* Naming sims in ''VideoGame/TheSims'' after Greek gods or old Hollywood stars sometimes gives special benefits and gifts to those characters.
** Ditto with ''VideoGame/RollerCoasterTycoon''.
** ''VideoGame/ZooTycoon'' too. Naming guests "Mr. Blue" or "Mr. Pink" after ''Film/ReservoirDogs'' will change the colour of all the guests' clothes.
*** Other names will result in far more dramatic results, such as the men in the park becoming violently ill, and [[Film/TheBirds birds inexplicably menacing the guests, causing widespread terror]].
*** There are animals you can unlock by finding Easter eggs too, mostly fantastic critters like unicorns or Bigfoot.
** And ''Theme Park World''. Naming customers after certain production team members causes them to stay longer or spend more money.
* ''SimCopter'' has one of the most famous Easter Eggs of all. In the finale, you are greeted by a throng of adoring citizens. Allegedly, the producer told one of the artists to include a bunch of bikini babes in the scene, without knowing that the artist was gay. Annoyed at the request, the artist included several speedo-wearing men, some of whom are kissing. Maxis fired him and was forced to recall early editions of the game.
* Also should note that in ''[[VideoGame/SimCity Sim City 3000]]'' and ''Sim City 4'', many of the office buildings are named after a person who helped develop the game ([[MemeticMutation like Wren Insurance]]). And let's not forget the ''biggest'' EasterEgg of them all; The California Plaza, where the Maxis studios is located, is a landmark players can build in their cities (actually quite snazzy looking too).
%% * Every game in ''VideoGame/TheSims'' including its two sequels all contain easter eggs.
* ''VideoGame/{{Drakengard}}'':
** After seeing all of the game's MultipleEndings. It involves doing a free mission in Tokyo and shooting down three or five jets of the Japanese Air Self-Defense Force, which is much harder than it sounds. After you accomplish this, you can choose to fly either your dragon or an SU-47 in free missions. This is a ShoutOut to Cavia Inc., who develop the ''VideoGame/AceCombat'' series of games and developed the [[SimulationGame Flight Sim]] half of the game. Did I mention that the protagonist is still mounted on the outside of the jet?
** Another can be found in Manah's castle. In the throne room there are four paintings. Three of them are nothing of note, but the fourth has a familiar face: [[spoiler: [[Manga/{{Berserk}} The Skull Knight]]]].
* In the third level of ''VideoGame/BattleTanx 2: Global Assault'' there are many cars scattered around the level, many outside the game area. They can be destroyed with careful blasting or a remote controlled rocket. One of these, upon destruction, will cue a whole series of messages from various employees who worked on the game. The theme is "We want to work hard on making a good game".
* ''Franchise/StarWars: VideoGame/JediStarfighter'' has ''literal'' Easter Eggs hidden in the Mount Merakan level.
* The ''Franchise/StarWars: VideoGame/RogueSquadron'' series has several Easter Eggs, such as a hidden level in the first game that lets you play as an AT-ST. All three games have a code that turns one of the ships into a flying Buick (yes, the car), and best of all the first game has a code that unlocks the [[Film/ThePhantomMenace Naboo Starfighter]]. This code wasn't discovered until six months after the game came out (which was also when the movie came out in theaters), when Creator/LucasArts unveiled it. Some of the people who worked on the game didn't even know about it.
* ''VideoGame/{{Creatures}}'' has many, but the most famous is Bustr.txt, a file which reads: ''Hunting scuba cows (A Poem) / Pebbles are not edible. It is fruitless to try eating them. / I have not eaten a sandwhich in many days. / Despair not for Wednesdays. / Salmon unite. / Boo hoo. / Bye. / Thankyou. ''
* ''Franchise/StarWars: Starfighter'' has a force-field cube with silly pictures in picture frames accessible by turning around at the beginning of the first level. Also, one mission features a missile frigate that launches two "Chris Corrpedoes", named for lead programmer Chris Corry.
* In ''VideoGame/WingCommander IV'', typing "animal" when the shipboard computer terminal text is scrolling, before it gets to the prompt for a callsign, results in a text based "20 questions" type game called "Animal Gump". Replacing "animal" with "chicken" gives an alternate version of the credits, with strange comments.
* ''F/A 18 Hornet'' has a literal giant easter egg floating over an airbase near Lake Bahr-al-Mith in Iraq.
* The HollywoodHacking sim ''{{Uplink}}'' combines this with GeniusBonus in a very interesting and thematically appropriate way. There are supposedly encrypted easter eggs hidden in the game's code. If you want to see them, find the right segments and crack the encryption keys.
* ''VideoGame/StarWarsRebelAssault II'' has several that are activated by holding down certain keys during a cutscene. One is a falling stormtrooper doing a Wile E. Coyote impression, another is a squad of dancing stormtroopers.
* In ''[[SilentHunter Silent Hunter 4]]'', you can find a [[http://www.youtube.com/watch?v=IUcpCs91__I Ghost Ship (the Flying Dutchman)?]] as well as...[[http://www.youtube.com/watch?v=MNA4tTwSOwM well.]]
* In ''VideoGame/{{Spore}}'', you explore an entire galaxy in the Space stage, so it would only make sense if you were to find at least a few good Easter eggs.
** You can find our solar system, Sol, and it has the most planets of any system in the game, including Earth. [[spoiler: Which, creepily enough, is a barren T0 planet, and can be colonised and terraformed (with or without monkey-like creatures) or even destroyed for the sake of [[MoralEventHorizon an achievement]].]]
** If you navigate your way through the heavily-guarded Galactic Core, you will meet Steve in his classic ship (as he appeared in ''SimCity 2000''). He will reward you 42 charges of the staff of life, which fully terraforms any planet to a score of T3 (the maximum), and will even ask you to visit the "third rock from Sol" (see above). Also, it will record this event in your history tab as your species achieving enlightenment.
* In ''VideoGame/KerbalSpaceProgram'' there are various objects hidden on planets. They are pretty hard to find, since planets (even the scaled down versions found in this game) are very large.


[[folder: Sports ]]

* [[TheReveal "Uh, don't tell the other kids, but, uh, I speak English. I learn Spanish in school."]] (Pablo in the original ''[[BackyardSports Backyard Baseball]]'' when you hold Shift while clicking on his player card.)
* There's at least one ''[[VideoGame/FootballManager Championship Manager]]'' game that allows you to play as an international team if you give yourself the same name as the manager of that team in the year the game was released.
* In the original ''VideoGame/WiiSports'', it's possible to throw the bowling ball in such a way that it starts rolling ''backwards'' instead of onto the bowling pin. Do so, and the crowd in the background will jump in surprise.


[[folder: Stealth ]]

* ''Franchise/MetalGear''. The whole series. The early ones have a few, but the ''Solid'' games contain more than you could possibly ever find -- to the point where it's almost closer to DevelopersForesight. They vary from bonus conversations, to lewd posters and jokes, to Konami Easter Island heads, to {{Running Gag}}s, to strange bonus items and scenes. You can get so much VideoGameCrueltyPunishment it's unreal, get enough FanService to last you the night, and even make the main character shave off his [[PermaStubble beard]] for the finale of the second game, if you decide you don't like it.
* The [[UpdatedRerelease Gold edition]] of ''VideoGame/{{Thief}}: The Dark Project'' features [[DebugRoom a hidden joke stage]], accessible by altering the configuration file, that intentionally exposes things players aren't supposed to see, such as bugs that were killed before final release and the placeholder texture, along with notes giving insights into the design process and some out-and-out gags.
** Then there's an EasterEgg basketball court (which doubles as a DeveloperRoom thanks to a scroll with the devs' quotes). It's hidden in the [[spoiler:training mission, but you can access it only if you select Expert difficulty]].
** ''Thief 2'' has a rather unusual one. In the level where you break into the City Watch HQ, if you throw a Scouting Orb over the wall immediately to your left when the level begins you can see a couple of zombies dancing.
* There's an incredibly obscure easter egg in the sixth-gen version of ''VideoGame/SpliterCellDoubleAgent''(it was so obscure that it wasn't until 2010 that someone finally discovered it). If you're playing co-op mode, [[http://www.youtube.com/watch?v=gbSXFKefmKw you can find baby seals hidden in Ellsworth Prison]] by shooting open lockers for clues. Once you find the seals, they give you more clues and ask you to fetch them certain objects. Giving them the wrong object results in mission failure.
* There are a few in ''VideoGame/HitmanAbsolution'', the most entertaining of which is unlocked by trying to show mercy to [[spoiler:Lenny]] via shooing away (and then shooting at) the gathering vultures. [[spoiler:[[BigLippedAlligatorMoment Then an ice cream truck comes out of nowhere and wallops Lenny into oblivion]]]]. The complete lack of reaction from 47 is also completely in character.


[[folder: Survival Horror ]]

* ''VideoGame/ResidentEvil2'' has three sets of film you can find and develop, which reveals photos related to the story. A fourth film can be found if you search Wesker's desk over ''50'' times. The fourth film contains a picture of Rebecca Chambers, a character from the first game, wearing a basketball uniform.
* In ''VideoGame/FiveNightsAtFreddys'', in all four games, clicking on Freddy's nose on a poster or on a plushie will play a honking noise. [[VideoGame/FiveNightsAtCandys Its]] [[VideoGame/FiveNightsAtTubbyland numerous]] [[VideoGame/FiveNightsAtFuckboys fan]] [[VideoGame/OneNightAtFlumptys games]] have similar easter eggs.


[[folder: Turn-Based Strategy ]]

* ''VideoGame/ShiningForce'' has two items which, when held by the appropriate (female) character, change that character's field sprites to ones with a little more {{Fanservice}}. In the English-language release, their names have been romanized, but not translated.
* ''Eschalon: Book 1'' contains three items called Easter Eggs. If all three are found they can be traded in to make the character advance a level.
* You have to be incredibly lucky or very persistent to see it, but in ''VideoGame/PhantomBrave'', you can generate anthropomorphic owl PlayerMooks. One of the possible names assigned to them is [[MemeticMutation Orly]].
* In the Special Edition version of ''Videogame/LordsOfMagic'', there are 4 official quests (Fire, Earth, Death, and Order) you can choose from. There's also a hidden fifth quest (based on the story of Siegfried, complete with German accents) that can be accessed by clicking on the center of the quest selection room.


[[folder: Visual Novel ]]

* In the Mirror Moon translation of ''VisualNovel/FateStayNight'', go to Caster's Info screen and go to her first skill page. A little Neko-Arc from ''VisualNovel/{{Tsukihime}}'' is in the corner of the text box.
* There's a special Easter Egg ending in ''VisualNovel/ZeroTimeDilemma'' where, [[spoiler: during the Q-Team MexicanStandoff,]] you have to manually type the name of who you want [[spoiler: to shoot, or no one if you wish]]. If you type in [[spoiler: Zero's real name]] then [[spoiler: Zero is killed instead.]]


[[folder: Western RPG ]]

* ''VideoGame/{{Fallout}}'' has many examples. [[http://www.nma-fallout.com/content.php?page=fo2-easter This link lists some]]
** In an example of this perhaps being taken too far, the ExpansionPack ''Mothership Zeta'' for ''VideoGame/{{Fallout 3}}'' is ''based entirely around one particular easter egg''.
** The "Wild Wasteland" perk in ''[[VideoGame/FalloutNewVegas New Vegas]]'' essentially places a bunch of Easter Eggs on the map that also double as {{Shout Out}}s to other media, including another crashed alien recon craft.
** On top of normal random encounters on the world map in ''1'', ''2'' and ''Tactics'', if the player is lucky enough, they'll run into a number of "special encounters", many of which are ShoutOut-laden EasterEgg material and often provide some pretty powerful items (though in the second game, there are some unlucky special encounters designed to screw over the player, such as sticking them in the middle of a field of [[MadeOfExplodium exploding Brahmin]], a heavily-irradiated toxic waste dump, or right next to the infamous [[DoomMagnet Pariah Dog.]])
* In ''VideoGame/UltimaV'' on the Commodore, yelling FLIPFLOP will flip the screen upside down.
* The "VideoGame/{{Gothic}}'' series has the Mighty Alien Dwarf, who leaves signed messages to the player, either in areas of the game that can't be reached without cheating or in places that there's no real reason to explore. One message not from the Dwarf is a rusted-out old car hidden deep in an uninhabited corner of the map, with a note from the game developer saying, "Well, I always wanted to make a game with cars, you know."
* One of ''VideoGame/NeverwinterNights'' bookshelf models has a book on top, titled "[=BioWare corp=]" on the cover and "This is a Book" on the spine.
* ''VideoGame/BaldursGate'':
** There's a character called "Peter of the North." It's clearly a joke on Peter North, the porn star. He talks about being a "master woodsman" and his console code is "coksmth." Not sure if that's exactly an Easter Egg; maybe a programmer was really into porn... [[JustForPun inconceivable!]]
** Fairly early in the game you can run into a ranger named "Bub Snikt", who claims that he's the best at what he does, and what he does ain't pretty. If asked to join your group, he claims he works alone.
** At another point you can meet "Lord Foreshadow", who makes oblique comments about trouble brewing down in Amn, and that he recently visited Neverwinter.
* The voice actors for [[PlayerCharacter Hawke]] in ''VideoGame/DragonAgeII'' must have had a ''lot'' of fun the day they recorded their combat lines; the source audio file archive [[http://impressioniste.tumblr.com/post/17106196066/dragon-age-ii-source-audio-easter-eggs-in-the includes]] such menacing battle cries as "There's a donkey in the spoon drawer!" and "This fish isn't working!"
* In ''VideoGame/TheWitcher2AssassinsOfKings'', you can explore a bit the courtyard from the La Valette castle and discover a [[http://images.wikia.com/assassinscreed/images/f/fe/Witcher2_Assassin.png dead man besides a broken hay wagon]], wearing hooded white robes and a bright red bend around his waist. When passing by, Geralt says "I guess they'll never learn".
* ''VideoGame/TaskMaker'' has several hidden spells accessible via "other spell to invoke". Some of them display silly messages, such as "eggs", which brings up the message "why did you say eggs?"
* ''VideoGame/{{Undertale}}'' has several:
** The door in the Snowdin Woods will open if you dodge all of the credits perfectly in the ending.
** If you do nothing but hum when facing [[UniqueEnemy Shyren]], this will have a mini-plot where you and she improve your singing careers. In game, this means you can cause Knight Knight to fall asleep faster by singing. This also activates Shyren's yellow title in the epilogue.
** Each character in the ending credits / epilogue has two descriptions. The first is a standard white description, and the second is a yellow description if you did something unique with them. One of the most obscure is Aaron's, which is triggered by wandering around the lake near Napstablook's house while the "Spookytunes" CD is playing.
** When you reach the Last Corridor on a Pacifist run, save the game before you talk to Sans. As soon as you stop talking to each other, reload the game and talk to him again. Keep doing this until you get the key to his room. Search his room for a silver key to the [[BehindTheBlack door behind his house]]. There's what is possibly a time machine there.
** There's a hidden encounter in Hotland. Follow the path from the Right Floor 2 elevator until you reach the long, straight area with a T-intersection. There's an invisible path going north.
** Unpacking the game allows access to a secret audio file from Toby politely asking them to not spoil secrets and post them on the internet. [[https://a.pomf.cat/uqezgy.ogg Take a listen.]]
** There's an Abandoned Quiche under a bench east of the second Bridge Seed puzzle room. You can use the seeds to get there.
** By changing a property in the ''Undertale.ini'' file, you can have some extra Fun with the game by hunting for secrets. However, should you get the Wrong Number Song to happen, then don't expect any Fun.
** If you play the game in windowed mode, the title of the game window changes several times:
*** During the opera segment in Hotland, it reads "Undertale: The Musical".
*** When you restart the game after Flowey forcibly closes it and the intro glitches out, the title cycles through random gibberish. Until you beat him, it reads "Floweytale".
*** If you finish a No Mercy run, the game has no title after the Fallen Child destroys the world.
** Related to the above: when the Fallen Child attacks the game itself and fills the screen with 9s, the window shifts and shakes repeatedly.
** If the game crashes (unintentionally) or if you launch Program Manager while the game is running, the game's internal description is "Leading Brand UNDERTALE-type software".


[[folder: Wide Open Sandbox ]]

* The ''VideoGame/GrandTheftAuto'' series is as a whole rife with Easter eggs. Notable ones include:
** The hidden "You weren't supposed to be able to get here you know" sign in ''VideoGame/GrandTheftAutoIII''. As a nod to this Easter egg, the UsefulNotes/PlayStationPortable and UsefulNotes/PlayStation2 versions of ''VideoGame/GrandTheftAutoLibertyCityStories'' include "Hello Again!" and "You just can't get enough of this alley, can you?" signs respectively in its place as if the developers were expecting players to revisit this spot again. And again.
** A [[{{Lampshade}} literal chocolate egg with "Happy Easter" written on]] in a secret room in ''VideoGame/GrandTheftAutoViceCity''. The [=PlayStation=] 2 version of ''VideoGame/GrandTheftAutoViceCityStories'' reintroduces the same room with the egg being under construction, complete with a miniature construction crane.
*** On a more cryptic note, players in ''Vice City'' can use a clipping exploit to view a picture hidden behind an Ammu-Nation wall of [[http://www.grandtheftwiki.com/File:Ammu-Nation-GTAVC-poster.jpg Ronald Reagan having fired a few rounds at a bulls-eyed picture of Mikhail Gorbachev]].
** ''VideoGame/GrandTheftAutoSanAndreas'''s "[[{{Irony}} There are no Easter Eggs up here. Go away.]]" sign on top of one of the towers of the Gant Bridge in San Fierro.
*** Furthermore, if you go to the Bridge's tourist gift shop, you will see [[http://www.grandtheftwiki.com/File:GantBridge-GTASA-cable.jpg a piece of the bridge's cable]], and a plaque describing [[http://www.grandtheftwiki.com/File:GantBridge-GTASA-factsboard.jpg how much disc space the bridge takes up]] (A "[[TechnologyMarchesOn staggering]]" 1.27 megabytes of space!).
** Recurring instances of Rockstar Leed's signature smiley seen on the aforementioned "Hello Again!" sign, as well as on multiple hidden signs in ''VideoGame/GrandTheftAutoViceCityStories'' (effectively serving an actual Easter egg hunt) and under the sea in ''VideoGame/GrandTheftAutoChinatownWars''.
*** The UsefulNotes/PlayStationPortable version of ''Vice City Stories'' has 12 of these signs, with one found under the sea reading "Nothing to see here"; the [=PS2=] version has that very sign altered to read "I wasn't joking, there really is nothing to see here. Go check out the VCN building instead!", referring to the newly reintroduced Easter egg room.
** The "[[http://www.grandtheftwiki.com/Statue%20of%20Happiness#Statue.27s_heart Beating Heart Of Liberty City]]" inside the Statue of Happiness in ''VideoGame/GrandTheftAutoIV'', "locked" behind a non-solid doorway bearing a sign reading "No Hidden Content This Way". It becomes less of an Easter egg in ''[[VideoGame/GrandTheftAutoIVTheBalladOfGayTony The Ballad Of Gay Tony]]'' when the interior of the statue is a possible respawn point after the player blacks out from excess drinking.
* ''VideoGame/SaintsRow2'' has an actual ''Easter Bunny'' that rises from the water.
** Someone caught it and boated it to [[VideoGame/SaintsRowTheThird Steelport]].
** In ''VideoGame/SaintsRowIV'', there's a "Developer's Room" hidden under the Let's Pretend store. It contains a wall of cardboard cut-outs with the development team's faces on them, along with [[spoiler: a new weapon, the [[Film/MenInBlack Loud Locust]].]]
* ''VideoGame/EndlessOcean'' has a lot of these, but they're either very small, unobtrusive, and possibly not intentional (the holes in the rock at Comb Reef, the various findable items, the out-of-season fish) or huge enough to stretch the definition of "egg" (the [[DerelictGraveyard Ship's Rest]] area, some of the aforementioned items). The only true EasterEgg is the [[spoiler:secret cutscene]] unlockable by sitting on the deckchair at sunset.
** There are a few other ones that are almost definitely intentional. [[ExpositionFairy Kat]] can be spoken to on deck, and usually provides information as to what you should do next. However, once story mode has been completed, she says random, sometimes [[ContemplateOurNavels navel-contemplative]], sometimes funny things. There's also another [[spoiler:secret cutscene]] unlocked by achieving OneHundredPercentCompletion.
* ''VideoGame/TheElderScrollsIIIMorrowind'' and ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' are full of [[http://uesp.net/wiki/Morrowind:Easter_Eggs Easter]] [[http://uesp.net/wiki/Oblivion:Easter_Eggs eggs]].
* In ''VideoGame/{{Vette}}'', driving off the far end of the Bay Bridge would lead you to Alameda, home of Spectrum Holobyte, the developers.
* ''VideoGame/ScarfaceTheWorldIsYours'' has this in dialogue trees. Unique conversations give performance bonuses. Talk to everyone (sometimes twice). That old lady in the hat? Tony Montana will try to pick her up. The masked wrestler really likes candy. And fried chicken. Tony even tries family counseling on a teenager wandering Miami Beach.
* In ''VideoGame/{{Minecraft}}'''s 360 Edition tutorial world, it's possible to find a pyramid which contains a strange tower - four blocks of gold, stacked atop one block of obsidian. This is a reference to LetsPlay/AchievementHunter's Minecraft videos, in which they compete to earn a "Tower of Pimps"... four blocks of gold stacked atop one block of obsidian!
* ''VideoGame/{{Subnautica}}'''s Seamoth submarine's built-in AI will occasionally say "I love it when you come inside me" instead of the usual "Welcome aboard, Captain" when you enter it.

[[folder: Misc ]]

* On the QWERTY type key arrangement, the word "Typewriter" is contained in the top row. Whether or not this is coincidence is debatable.
** According to Website/{{Cracked}}, this was so salesmen could easily type the word to impress potential buyers.
** "Secretary" can, intentionally or not, be typed entirely with the left hand. Hmm.
* If you're playing the {{Macintosh}} version of ''any'' shareware game made by Creator/AmbrosiaSoftware, press 'X' on that game's title screen for an Easter Egg. (The individual games contain many additional eggs, like ''VideoGame/EscapeVelocity'''s "forklift"--a LethalJokeItem that can only be obtained, with difficulty, while viewing ''another'' egg.)
* A particularly common form of Easter egg is a "[[DevelopersRoom programmers' room]]". A well-known example is found in ''VideoGame/ChronoTrigger''.
* Creator/{{Nintendo}} composer Kazumi Totaka is notorious for hiding a short, 19-note melody in most of the games he's worked on, sometimes so well-hidden that fans are still trying to find it in various games, years after their release. The usual method seems to involve pausing the game at some certain place and then waiting a few minutes.
** ''VideoGame/TheLegendOfZeldaLinksAwakening'' even contains three distinct versions: wait in Prince Richard's house for 2 minutes and 30 seconds for one version, enter とたけけ (Totakeke) as your name in the Japanese version and, in the ''DX'' version, MOYSE [[RegionalBonus in the German localization]] (ZELDA in the US localization of either and "LOLO" in the French localization of the ''DX'' version play a remixed ''Zelda'' overworld theme instead) for a second version, and a third version that exists in the game code but can't be accessed in-game (or at least no one knows how), while the German translation of ''DX'' is the only international release known to have the second one accessible in-game (with Moyse being the last name of the German translation's writer, Claude Moyse). In the black-and-white version of the game, "MOYSE" in the German translation plays a song unique to that version while "LOLO" in the French translation plays a song unique to it, but the ''DX'' version replaced them with something less unique, as previously mentioned.
** Not only is it hidden in games, but it is also hidden in ''VideoGame/AnimalCrossing'' ''New Leaf'''s ''[[http://www.nintendo.co.uk/Games/Nintendo-3DS/Animal-Crossing-New-Leaf-273841.html European website]]''! [[spoiler: Just click on K.K. Slider to play it.]]
** ''VideoGame/SuperMarioLand2SixGoldenCoins: Wait at the ''Game Over!'' screen for 2 minutes.
** ''VideoGame/YoshisStory'': Wait on the "Trial Mode" screen.
** ''VideoGame/MarioPaint'': Click on the "O" of the Mario Paint title.
** ''VideoGame/AnimalCrossing'' games traditionally feature it as "K.K. Song", available on request only from K.K. Slider. In ''Animal Crossing: New Leaf'', Kapp'n will also whistle it if you linger on the Island connection screen for about 2 minutes and 30 seconds, although most players will never hear this because it requires a ''really'' bad internet conection.
* Somewhat of a visual version of the Totaka tune is the [[http://www.dopefish.com/fishinfo.html Dopefish]], first found in ''VideoGame/CommanderKeen 4'' and afterwards spread to countless games.
* All Dreamcast game discs have an audio track stating that the disc is for Dreamcast. Sometimes, this track is generic; other times, it's performed in character ("[[VideoGame/SkiesOfArcadia We can't save the world from a CD player, so just put us back in a Dreamcast, so we can do our jobs!]]").
** The obscure Dreamcast game ''Seventh Cross: Evolution'' has a truly unique twist on this practice; the audio comes from what can only have been ''cutscenes removed from the game proper''.
** ''VideoGame/{{Shenmue}}'' spans three discs; each disk's audio track is performed by a different character.
** ''[[VideoGame/{{Bomberman}} Panic Bomber]]'' for the [[{{TurboGrafx-16}} PC Engine/TurboGrafx-16]] also had such a track, featuring Shirobon (White Bomber) and Kurobon (Black Bomber).
* Often mistaken for an EasterEgg: Hold down the Start and Select buttons as you start up a GameBoyAdvance; the Nintendo logo under the Game Boy Advance logo will disappear with a four note jingle reminiscent of some sound effects in ''{{Mario}}'' games. The A button will make the logo reappear and make the game continue booting. In fact, it's actually just a method of overriding the cartridge slot so that downloads through the Link Cable (e.g. for single-cart multiplayer games, from a [[UsefulNotes/NintendoGameCube GameCube]]) will work without you having to pull out the game that's already in there. Believing that this is an EasterEgg shows that someone didn't ReadTheFreakingManual.
* Similarly, try holding down the Z button as you start up a [=GameCube=]. Now try holding down the Z buttons on all four controllers at once as you start it up.
** This also works for holding Z on the first two controllers, but not the first three, sadly.
* While examining a painting of [[spoiler:Flora]] in ''ProfessorLaytonAndTheCuriousVillage'', if you try to touch her breast when you're supposed to [[spoiler:find the mark of the Golden Apple]], the Professor will say "Now Luke, be a gentleman."
* In the special edition of ''VideoGame/BioShock2'', you have several posters advertising Rapture. On each one of them is [[spoiler: Rapturian graffiti in UV-sensitive ink that is only visible under a blacklight. This is hinted at NOWHERE on the poster.]]
* It was discovered that the [[UsefulNotes/NintendoGameCube GameCube]] system menu's ambient background music is actually [[https://youtu.be/rjEsXf3SJ6o?t=1m4s a version of the Famicom Disk System startup music slowed down to about 1/25th of the original speed]].
* The hidden object game ''VideoGame/MysteryCaseFiles: Dire Grove'' contains an EasterEgg that can only be solved if you complete the game ''twice'': once to view the clues that appear in the closing credits, and a second time to solve them and access the egg.
* ''VideoGame/WarioWare: D.I.Y.'' has an interesting one that made a lot of ''MarioPaint'' fans giddy. If you enter the Game [=MakerMatic=] and name your game "Mario Paint", you'll hear one of its [=BGMs=] as you draw. (If you change the name to something else, though, the music goes away.)
* In the Solar System installment of the ''Literature/MagicSchoolBus'' educational CD-ROM games, there is a video camera sitting on a desk in the classroom. It normally does nothing. When you flick the lightswitch in the room to make everything pitch black, and then click the video camera, it makes a screen appear on the blackboard of the classroom. You can then watch things such as the credits, more information about the Solar System, or a video about how if a person comes into your school dressed as Miss Frizzle, you should "start packing" (you can't travel through the Solar System in one day!).
* In ''[=FreeCell=]'' entering game number -1 or -2 results in an unwinnable deal, while (in the newest version) entering -3 or -4 yields a deal that can be instantly won.
* ''Vectron'' for the UsefulNotes/{{Intellivision}} would display a message from the programmer if the player did an [[http://www.intvfunhouse.com/games/vect.php#eastereggs incredibly difficult series of maneuvers]] for seven levels. As with Atari's ''VideoGame/{{Adventure}}'', this Easter Egg was hidden because Mattel had a policy against crediting programmers.
* The music player program on the Nintendo [=DSi=] and the UsefulNotes/Nintendo3DS has various sound effects you can play with the L and R buttons and one of them is the iconic coin sound from ''VideoGame/SuperMarioBros''. Playing the coin sound [[LawOfOneHundred 100 times]] plays the 1-Up sound effect at the 100th press.
** Also when in the sounds that you can record, move the cursor over any particular sound you want, wait a few moments and [[VideoGame/{{Super Mario Bros}} 1-1]] will start playing, using the first split second of the sound you recorded.
* The console versions of ''VideoGame/CapcomVsSNKMillenniumFight2000'' has an ''accidential'' one, which doubles as a BilingualBonus, where in the options menu, an radio advertisement for a Brazilian beer, Kaiser, can be heard if listened closely. Hear it [[http://youtu.be/eJKuv_k7e60?t=30sg here]]. Said ad also makes it to a song in ''[[http://www.youtube.com/watch?v=LqlgAFhy9s0 DJ Max Portable 3]]''.
* Sonic3AndKnuckles has the Videogame/BlueSphere mini-game, which can be activated by placing any Sega game cartridge into the top slot (something the instructions specifically tell you not to do) and pressing three buttons on the controller simultaneously.
* A nostalgic easter egg can be found within ''VideoGame/PokemonGo'': if you select Pikachu as your Buddy Pokémon, he will jump on top of your shoulder as you walk around, similar to how Pikachu travels with Ash in the anime.

However, entering it in ''VideoGame/BubbleBobble'' also resulted in the first[[note]]unless a higher bonus had been earned, in which case that one appeared first[[/note]] bonus item to appear in the next game to be a [[{{Pun}} fork]].
* One UsefulNotes/ZXSpectrum publisher likewise censored various high-score entries in amusing ways; for instance, entering "t.bridge" (a ShoutOut to Tony Bridge, a popular adventure-game columnist at the time) resulted in it being entered as "Not enough [[VideoGame/TheHobbit1982 Hobbits]] I suppose?".

* Creator/DonRosa has written a hidden dedication D.U.C.K (Dedicated to Uncle Carl from Keno) on each DonaldDuck adventure he has drawn
** Also, he hides Mickey Mouse or an object shaped like Mickey in most of his comics.
* Brian Cronin has collected [[http://goodcomics.comicbookresources.com/2011/07/01/a-month-of-comic-book-easter-eggs-archive/ a massive collection of these]] at Comic Book Resources, all from fan suggestions. Some include:
** Numerous comics strip characters appearing as [[ComicBook/FantasticFour Reed and Sue Richards' neighbors]]
** [[UnsoundEffect Hidden sound effects]]
** The ComicBook/XMen randomly appearing in the background in a ''{{Punisher}}'' issue
* Each Issue #1 of [[ComicBook/{{New52}} The New 52]] (with the exception of ''[[{{ComicBook/Earth2}} Earth-2]]'') included a one-panel background appearance by [[http://static.tvtropes.org/pmwiki/pub/images/rsz_1pandora_new_earth_001_998.jpg Pandora]]. [[http://images.wikia.com/marvel_dc/images/4/44/Pandora_Catwoman_001.jpg Here she is hidden in the first issue of Catwoman]]
* When Todd [=McFarlane=] did the art for ''[[ComicBook/SpiderMan The Amazing Spider-Man]]'', he always hid WesternAnimation/{{Felix the Cat}}'s face somewhere in it.

[[folder:Computer Software]]
* There are [[http://www.cg.tuwien.ac.at/~scheich/Newton/OS1.html two]] [[http://www.cg.tuwien.ac.at/~scheich/Newton/OS2.html pages]] of Easter eggs for the Apple Newton handheld computer, including Finder's ability to predict Elvis sightings...
* Microsoft Excel 97 had a hidden Flight Simulator mode that could be triggered by inputting a specific set of commands while in a brand new spreadsheet.
** Similarly, users of Microsoft Excel 95 could reach a ''VideoGame/{{Doom}}''-style "[[http://www.youtube.com/watch?v=nwg9eLHZZRo Hall of Tortured Souls]]".
*** Finally, Excel 2000 featured a ''VideoGame/SpyHunter'' style driving game dubbed "Dev Hunter" by its fans.
** In Windows 3.1, a certain sequence of keys would replace the Windows logo in the "About Windows" dialogue with a portrait of Bill Gates or (depending on what code was entered), a polar bear.
** Windows 95 had a feature whereas, in Explorer, you created a folder on the desktop named "and now, the moment you've all been waiting for" then renamed it "we proudly present for your viewing pleasure" then finally renamed it "The Microsoft Windows 95 Product Team!" the directory window would show a video (complete with music) of all the people involved in creating Windows 95. This was removed in Windows 95 C though (the final version of it).
** [[http://support.microsoft.com/kb/232010 Older versions of the 3D Text screensaver]], upon having "volcano" input as the text, would display the names of random volcanoes.
** The "Pipes" screensaver would sometimes manifest a teapot at one of the angles in the pipes it drew.
*** And not just any teapot either, but the original [[http://en.wikipedia.org/wiki/Utah_teapot Utah Teapot]] that was the model for the very first 3D render.
*** There's also a sugar bowl that appears ''very'' rarely.
*** [[Literature/ASeriesOfUnfortunateEvents Ahah! Microsoft is tied to V.F.D.!]]
** There is the Internet Explorer 4 credits. The [[http://www.eeggs.com/items/729.html series of manoeuvres]] that unlocks them is as fun to do as the credits, which feature silly "intermissions" between sets of names, are to watch.
** In some versions of Microsoft Word, typing in "zzzz" and running the spellchecker will cause it to provide the alternative spelling "sex".
** Any form of EasterEgg in Microsoft products [[http://blogs.msdn.com/larryosterman/archive/2005/10/21/483608.aspx has been banned]] by ExecutiveVeto ever since 2005. Why? Corporate customers do not appreciate undocumented bits in their software; apart from wasting work hours, they can introduce security flaws (this has happened before).
* In Mac OS 7.5, making a text clipping of the words "secret about box" and double-clicking it would reward you with a game of ''VideoGame/{{Breakout}}'', with developers' names printed on the blocks.
* Most versions of Borland Delphi will display information about and photos of its development team in its About box if you hold down the Alt key and type in words like "TEAM" or "DEVELOPERS".
* The Mozilla and Firefox browsers have a special response to typing "about:mozilla" in the URL input, verses from a fictional religious text called "The Book of Mozilla". Doing this in some versions of Internet Explorer, meanwhile, gets you a (false) Blue Screen of Death.
** Pale Moon, a fork of Firefox, shows instead a note of thanks to the original developers, but also a lament for what it had become.[[note]]Recent versions of Firefox have been criticized for abandoning the traditional user interface in favor of a minimalistic, non-standard one similar to Google's Chrome.[[/note]]
** Firefox 3 (and later versions) include additional about: pages, including [[spoiler: about:robots]].
*** The bullets all reference various pieces of fiction. "Robots may not injure a human being or, through inaction, allow a human being to come to harm." is the first of Creator/IsaacAsimov's laws of robotics. "Robots have seen things you people wouldn't believe." is from ''Film/BladeRunner''. "Robots are Your Plastic Pal Who's Fun To Be With." is a quote from Franchise/TheHitchhikersGuideToTheGalaxy. "Robots have shiny metal posteriors which should not be bitten." is a reference to Bender from WesternAnimation/{{Futurama}}. "And they have a plan" is a reference to the Cylons in Battlestar Galactica.
** The original [[http://www.seamonkey-project.org/ Seamonkey]] contains "about:kitchensink", due to reports that Mozilla had everything but the kitchen sink. [[https://bugzilla.mozilla.org/show_bug.cgi?id=122411 An actual bug]] was created to remedy the situation.
** [[https://bugzilla.mozilla.org/show_bug.cgi?id=700000 Bug #700000]]: Buy Firefox developers some beer. (This may be a reference to the software licensing term "beerware", which is a very lax license that allows users to do whatever they want with the software if they buy the author a beer should the user meet him or her, or at least drink a beer in the author's honor. However, Mozilla's software is not beerware, being licensed under the Mozilla Public License.)
* The Windows-only version of [[http://www.chromium.org/ Google Chrome]], 1.0, takes the URL "about:internets" and displays Windows's 3D Pipes screensaver; a ShoutOut to the infamous "it's a series of tubes" MemeticMutation.
* ''Mavis Beacon Teaches Typing'' has a pinball game hidden within it.
* The antimalware program ''Spybot- Search & Destroy'' has a hidden minigame based on the [[http://en.wikipedia.org/wiki/Knight%27s_tour knight's tour problem]].
* Try to find a version of Flash that does not have goodies hidden behind a tiny button in the about window.
* Matlab, despite being a serious program for mathematics has quite a few Easter Eggs, see the [[http://www.eeggs.com/tree/422.html full list]].
* Using the KonamiCode (up up down down left right left right B A) in Google Reader will give the sidebar a ninja theme.
* In Photoshop 6, holding Ctrl + Alt and going to Help and About will reveal an image of a blue anthropomorphic cat in BDSM gear, titled "Venus in Furs".
* In Python v.3 or later, you can type [[Webcomic/{{Xkcd}} import antigravity]]. It brings up that comic in your browser.
* In [=WinRAR=]'s "About [=WinRAR=]" window, clicking on the [=WinRAR=] icon will cause it to be affected by gravity (i.e. fall then bounce when it reaches the bottom of the window).
* A small easter egg can be found in Google's Calendar widget icon in Jelly Bean. If one were to look at the widget icon join the widget menu, an appointment for a time travel demonstration in a [[Series/DoctorWho police box]] becomes apparent, and with a very fitting shade of blue for the event.
* The program µtorrent has a ''VideoGame/{{Tetris}}'' clone hidden. Go to the "About" tab, then press "t".
* Hitting the up-arrow or spacebar keys on Google Chrome's "not connected to the Internet" page unlocks a minecart-type game where you have to guide the little dinosaur from the error page over cacti.
* Every version of the Android operating system has a different easter egg that can be found by going into the "about device" section of the system settings and quickly tapping the Android version number several times. Android Lollipop (5.0) and Marshmallow (6.0) hide a ''VideoGame/FlappyBird'' clone here, while Android Nougat (7.0) will add a ''VideoGame/NekoAtsume''-like game to the quick settings (Android Neko).
** Additionally, tapping the build number 7 times will unlock the otherwise hidden "developer settings" on most Android devices.
** If you dial in the number [[Series/TheITCrowd 0118 999 881 999 119 725 3]] on the Google Dialer, the dial button will start to flash like an ambulance's siren.
* The [=iPhone=] app "Siri" has [[DevelopersForesight dozens upon dozens of smart-ass responses to voice commands users might give]]. If you ask her to "open the pod bay doors," she will say... well, if you know that line, you know [[Film/TwoThousandOneASpaceOdyssey the answer.]][[note]]For the curious, her response would be "I'm sorry Dave, I'm afraid I can't do that"[[/note]]
** Amazon's voice-activated assistant "Alexa" (which powers the Echo and the Echo Dot) also has the above.[[note]]Her response is "I'm sorry Dave, I'm afraid I can't do that; I'm not HAL and we're not in space"[[/note]] Alexa has at least 200 easter eggs; another good one is [[Literature/TheHitchhikersGuideToTheGalaxy "What is the meaning of life?"]].
* A small and interesting easter egg can be found in the mobile version of Windows 10. The default wallpapers are located in the Photos app under the date April 1975. However, this is not just any ordinary date, nor is it random: April 1975 is when Microsoft was founded--specifically April 4, 1975.

* The DVD of ''Film/AustinPowersTheSpyWhoShaggedMe'' contains a secret menu, accessed if you wait around long enough on the special features menu for Dr. Evil's spaceship to fly into frame, and select the logo on it. The menu has several bonus features about, well, evil.
* The DVD set of ''WebAnimation/BrokenSaints'' contains several, the crown jewel of which is a hilarious alternate commentary track on Chapter 19, Act 1, which is practically a GagDub of the chapter.
* Most of the [=DVDs=] from the Creator/ADVFilms release of ''Anime/{{Noir}}'' contain {{Easter Egg}}s, including four [[FanVid anime music videos]] on disk 7, and a live-action mini-film featuring sock puppet versions of the main characters on disk 6 (called "Noir: The Unsoled Story").
* The English subtitled version of ''Manga/UruseiYatsura'' has Easter eggs in the subtitle text. Lum's mother only speaks an untranslated alien language. The subtitle, to show that even in the original language the dialog is unintelligible, is written in the "Symbol" font (The Greek letter font). By matching the characters to a regular font yields hidden messages. One message was "the star wars parody was pretty cool", which is not what she would be saying, but instead referred to an earlier bit in that episode.
* In the DVD Collection of ''Manga/ExcelSaga'', there are several Easter Eggs. At the start of each disc, rather than displaying the typical FBI warning screen, there is a warning (presumably written by Excel) stating "Il Plazzo is watching you!" and threatens the viewer if they illegally copy the discs. On Disc 3, Excel mention there are Easter Eggs on the [=DVDs=]. The majority are on Discs 2, 4 & 5 and include recipes, personal advertisements and poems.
* ''Series/DoctorWho''
** Actually uses as a plot point: in [[Recap/DoctorWhoS29E10Blink "Blink"]], the Doctor hides a message for the future in Easter Eggs in 17 unrelated {{DVD}}s. Appropriately, the message became a real-life Easter Egg on the Series 3 boxset.
** On a side note, it is worth noting that [=DVDs=] of classic ''Doctor Who'' stories are stocked with Easter Eggs whereas the only Egg on releases of the new series so far is the "Blink" message. Hmmm...
** The series 1 and 2 DVD set have the "Do you want to come with me?" promotion as an Easter Egg.
* The DVD version of ''Film/TheLordOfTheRings: The Two Towers'' contains a hidden video clip of Gollum accepting a MTV award for Best Animated Character.
** ''Film/TheLordOfTheRings: The Return of the King'' has an interview between Hans Jensen (as played by Dominic Monaghan) and Elijah Wood. Something of a [[http://www.youtube.com/watch?v=eLBDNUvrGQk Crowning Moment Of Funny]].
** ''The Fellowship of the Ring'' Extended DVD has a [[http://www.youtube.com/watch?v=o8ohAwSdIw8 remake of the Council of Elrond scene featuring Jack Black]].
* Not unlike the ''Noir'' example above, ''Anime/{{Madlax}}'' also has a sock puppet short on Volume 6.
* And so does ''WesternAnimation/TheIncredibles'' on the second disc of the DVD release.
* ''WesternAnimation/TheIncredibles'' has about half-a-dozen easter eggs, one of which is on Disc 1. One of the more awesome ones is a montage of every door, button and explosion in the movie -- set to the Anvil Chorus for added awesomeness.
* On the DVD of ''WebVideo/DoctorHorriblesSingAlongBlog'', when the standard FBI warning changes to the ELE screen, there is an intercut shot of three actual eggs, representative of the DVD's three hidden Easter eggs. Watching the first scene with the subtitle language set to "Wiccan" gives a coded hint to finding them.
* The [=DVD=] of ''Film/{{Memento}}'' has an Easter Egg on the main menu that lets you watch the film in chronological order.
* ''Film/TheHitchhikersGuideToTheGalaxy'' DVD has a rather odd Easter Egg when you use the Infinite Improbability Drive. It shows a rather... strange cartoon.
** In fact, it's the same cartoon that Deep Thought is watching within the movie.
** The DVD of [[Series/TheHitchhikersGuideToTheGalaxy the 1980s TV series]] has a similar feature, which turns up totally at random when you push any button on the menu, and basically [[InterfaceScrew shows whatever it was you wanted, but in a weird messed up way]] with an apology for the effects of the Infinite Improbability Drive. Interestingly, the TV series DVD predates the films release by at least a year.
* The DVD's of ''Anime/FullmetalAlchemist'' feature some Easter eggs, usually by going to the extras menu and using some button/key presses to highlight a special symbol (or a letter in the logo). The majority of these Easter eggs are gag dubs of the next episode previews with the Japanese cast acting out of character (For example, the gag dub preview of one of the episodes has Winry's VA singing an alternate version of 'Tobira No Mukoe E' with lyrics that basically make fun of Ed), other Easter eggs include things like adverts. Sadly most of these bonus features were absent on the UK releases (With one DVD having a functionless egg)
* The DVD of ''Film/TheRing'' has a secret option on the main screen, if you scroll down through all the normal options, the cursor will disappear. Hit enter, and the DVD will play a (slightly extended) version of the cursed video, followed up by returning to the main screen with a phone ringing in the background. Once it starts playing, it cannot be stopped, paused, scrolled through, or in any way halted short of turning off your player.
* ''Film/TheMatrix Revisited'' DVD had a secret list of about 64 songs that could be accessed by clicking on a phone booth in the background. This being ''The Matrix'', I'm sure there's others in ''Animatrix, Reloaded'', and ''Revisited''.
* Press up when the cursor is on the "play" button on the DVD of ''WesternAnimation/{{Madagascar}}''. There's a video depicting the development of the movie's animation, with added CrowningMusicOfAwesome.
* The fourth disc of season one of ''Series/{{Life On Mars|2006}}'' has a cell phone next to the ash tray that leads to an Easter Egg when you click it.
* The DVD release of Music/DuranDuran's ''Greatest'' video collection contains a number of Easter eggs which the viewer can get to either through a series of convoluted steps, or by going directly to the "track number" in each DVD. The Easter eggs include archival footage of the band playing at the Rum Runner nightclub (where they were the house band) while the New Romantic clubgoers dance around, soundtracked to "Planet Earth"; scenes from a 1984 British TV interview with the band featuring little sound clips of the slowed-down version of their instrumental "Faith in this Colour"; and a lengthy 1990 interview of the band talking about the creative process and the way their then-current album ''Liberty'' came to be.
* ''Film/SpiderMan2'' has a couple of memorable Easter Eggs found by moving the cursor off the list of items in a couple of the DVD menus. One has Sam Raimi claim that he's brought in an expert to show Alfred Molina how he wants a scene to be done. [[spoiler:The camera pans over to show Willem Dafoe acting out one of Octavius' scenes, and Molina breaks down laughing.]] Another starts with Molina as Doc Ock snarling at the camera...before breaking out into "[[Theatre/FiddlerOnTheRoof If I Were a Rich Man]]", with the [[http://www.jest.com/video/604/dr-octopus-sings-showtunes puppeteers making Ock's tentacles dance along]].
* The ''Series/BabylonFive'' DVD collections contain bloopers and outtakes from the season you're currently watching. All one has to do is find the hidden "5" symbol in the extras menu on the 6th disc of each season.
* Several [=DVDs=] of the ''Franchise/StarWars'' films contain Easter Eggs, including bloopers and the like, and are often revealed by inputting "1138". In the DVD for ''Film/AttackOfTheClones'', select a poster behind Dex in his diner and you'll access a slideshow of rough, hand-drawn student posters: one has [=C-3PO=] advertising a Spanish language class.
* You have to decipher some codes and do some lucky guessing on the ''Film/NationalTreasure'' DVD to get your Easter Egg.
* One of the [=DVDs=] in the Firefly set features Adam Baldwin singing "The Ballad of Jayne"
* In the title menu of Film/{{Serenity}}, there's a hidden button leading to a clip about and showing the Fruity Oaty Bars ad.
* On one of the discs in the ''WackyRaces'' DVD set, one of the menu screens has two hot spots that lead to pre-commercial bumpers.
* The first DVD of the 3rd ''Anime/TenchiMuyo'' [=OVA=] series has a hidden subtitle track in the first episode [[spoiler: which contains the actual translation of Washu's "magic fingers" incident.]]
* On {{Rush}}'s ''R30'' [=DVD=], there's a documentary about their titular tour, and if you press one on your remote at a certain moment, [[BigLippedAlligatorMoment a cartoon plays depicting Geddy Lee and Alex Lifeson as dogs(and Neil Peart as their owner), then depicting them all as fighting robots, set to their classic song "By-tor And The Snow Dog"]].
* All of the [=DVD's=] for ''Series/RedDwarf'' have easter eggs in the menus. Sometimes obvious (hit the 'go' button on the Holly Hop drive), sometimes not (When the video pauses in the airlock, hit the green button. You have about three seconds). They generally lead to interviews and videos of the cast goofing around. A list can be found on eeggs.com, [[http://www.eeggs.com/tree/80.html here]].
* ''SorcerorStabberOrphen'', at least in the English release, has some hidden content. You'll probably need to run this on the computer, because some of these will likely be missed just with a menu cursor. These have mainly character outtakes, or private humor.
* Creator/FUNimation's DVD release of ''Anime/LupinIIIVoyageToDanger'' hid the access to an Easter Egg by forcing you to switch to certain menus in a certain order. An audio clip could then be accessed by the viewer. [[spoiler: You hear Lupin (Creator/{{Sonny Strait}}) and Zenigata (Creator/PhillipWilburn) drunkily singing the series' theme song, followed by Goemon (Creator/MikeMcFarland) lampshading the easter egg's absurdity.]]
* One of the Easter eggs on the ''Film/Gremlins2TheNewBatch'' special edition DVD is the alternative VHS version of the scene where the Gremlins stop the film. It can be seen if you select the Gremlin's hand on the main menu.
* The special edition DVD of ''Film/ThePhantomOfTheOpera2004'' has an Easter egg of the crew hilariously trying to sing the title song.
* The ''WebAnimation/HomestarRunner'' [=DVD=]s have a few easter eggs, much like the site itself.
** The easter eggs that are normally accessed at the end of the cartoons are accessed by fiddling around with the arrows buttons until an icon pops up. On the Strong Bad E-mail [=DVD=]s, it's a Strong Bad head; on the Everything Else [=DVD=]s, it's the Homestar Runner logo. There's also some easter eggs on the special features menus of each [=DVD=] that are accessed the same way.
** The easter eggs that are normally accessed during the cartoons are accessed by using the angle button. Most [=DVD=] players will display when the angle button can be used.
** Most of the cartoons include hidden DVDCommentary by changing the audio track.
** [=Strongbad_email.exe=] Disc 2 has the files for "Strong Bad's Website" and "Strong Sad's Lament" (with the update from the time) on the disc that can be accessed by exploring the [=DVD=] on a computer. Appropriate, because the WebAnimation/StrongBadEmail, "website", is on the [=DVD=], and the two websites were accessed through the cartoon on the actual website.
* ''Series/TheITCrowd'' [=DVD=]s have "Leet" Subtitles for each episode. During the first season, most were simply the regular subtitles with letter substitutions to make convert it into leetspeak, but one was a stream of [[https://en.wikipedia.org/wiki/Base64 Base64]], which turns out to be an encoded version of the subtitle track. The second season's DVD ups the ante by having the Base 64 code fill the entire screen. Hope you know how to rip the subtitles and convert them into the right file format! (It later turned out to be a secret competition which nobody won since it was too hard, [[http://www.youtube.com/watch?v=9ZOZ3lhMyL8 as explained in an extra on the third series DVD]].)
* The DVD menu of ''Film/WaynesWorld'' has some Easter eggs hidden in plain sight: The menu is set up to look like a cable TV guide, with the actual options surrounded by campy titles you might see on late night TV, namely ''Series/TheBradyBunch'', ''Solid Gold Workout'', and the 1979 comedy ''Sunburn'' starring Farrah Fawcett. You might think these gag options wouldn't actually be clickable, but they are: Selecting them gives you a short clip of the selected show/movie, with a small line of text advertising its availability on video on the bottom of the screen.
* ''Anime/NeonGenesisEvangelion'''s "platinum collection" DVD release by ADV Films had four separate audio tracks for the final episode. Along with the usual English and Japanese tracks and the commentary, there was one which appeared to be entirely blank...[[https://www.youtube.com/watch?v=kGMuaXIlckU until you got to the credits, that is.]]
* The DVD of WesternAnimation/ToyStory2 has one which is an extended version of the sequence where Emily drops Jessie off at the charity donations site. This was promoted on the Blu-Ray to a non-hidden extra.

[[folder: Fanfic]]
* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' FanFic ''[[http://www.fimfiction.net/story/152876/a-glimmer-of-hope-in-the-black A Glimmer of Hope in the Black]]'' has several, the most prominent being invisible text at the end of the story that can only be seen by highlighting it with your mouse. The text itself is gibberish and must first be run through a cipher to reveal a message from a character who has apparently broken free from the virus and is trying to alert the reader of a new plan to stop it from spreading.

* ''Film/TheRockyHorrorPictureShow'' has several actual Easter eggs hidden in the scenery.
** It's rumored Rocky Horror actually ''started'' the concept of Easter Eggs. And did so by having an Easter egg hunt on the set, and some of those that weren't found made their way into the film. How much truth there is to this rumor is debatable.
* In ''Film/ManOfSteel'' during the final battle, there are trucks that explode. The logo on one truck is the Lexcorp logo.
* One song on the soundtrack to ''Film/{{Inception}}'' is "Non, je ne regrette rien", just slowed down.
* ''Film/{{Elysium}}'': Look very closely during the final montage of the joyous citizens of Earth welcoming the medical shuttles. There's a blink and you'll miss it shot of Johannesburg... with the alien ship from District9 still hovering over it.
* ''Film/{{Godzilla 2014}}'':
** During the exploration of Janjira, the camera moves in front of an aquarium with word "mothra" scratched on it. In the ''Godzilla'' canon {{Film/Mothra}} is a friendly GiantFlyer.
** In the prologue, a diagram of a moth is briefly shown, bearing the same colours scheme as Mothra.
* In Film/TheSpyWhoLovedMe, the American submarine ''USS Wayne'' has hull number 593 on her sail. That hull number belonged in the RealLife to ''USS Thresher'' (SSN-593), a nuclear submarine which disappeared in 1963.
* In ''Disney/LiloAndStitch'', the pink slip adoption paper that Lilo signs to adopt Experiment 626 as "Stitch" [[BreakingTheFourthWall refers to the film's production in the fine print]].
* Fans of General Mills cereals Count Chocula, Boo Berry, and Franken Berry might not remember that they had another "monster cereal" called Fruit Brute which wasn't very successful, but director Creator/QuentinTarantino remembers it with some fondness. In ''Film/ReservoirDogs'', there's a box of the cereal in Mr. Orange's apartment, and Lance is eating it in a scene in ''Film/PulpFiction''.
* ''Film/WarGames'': During the scene where David initiates the game, he says "sometimes people make mistakes." If you look at the screen afterwards, you can see that he demonstrated this himself by typing "sometimes people make mistak".


* The covers and illustrations of J.R.R. Tolkien books do contain hidden messages by the author written in Tengwar alphabet.
* There are possibly hundreds of Easter Eggs in ''Literature/HouseOfLeaves'', mostly because of the use of ciphers to hide words or messages in certain phrases throughout the book. A good rule of thumb for finding them is to pay attention to oddly-worded or seemingly nonsensical sentences, take the first letter of each word, and see what you get. One letter of Pelafina's is written entirely in this cipher. There are also phrases that make no sense unless you say their [[BilingualBonus sound-equivalent in a different language]] (usually Latin, as indicated in another of Pelafina's letters).
%% [[VideoGame/{{Portal}} Well, you found me. Congratulations. Was it really worth it?]] I mean, seriously, don't you have anything better to do, you poor excuse for a human being? Get a life. Oh, who am I kidding, you just used the Find feature, didn't you, [[WebAnimation/ZeroPunctuation Adrian]]?
* In most of the ''Literature/ArtemisFowl'' books, there is a code running along the bottoms of the pages. Ostensibly the message is in Gnommish, the fairy language of the books, but is actually a simple substitution cypher. If you translate them, they are funny or quirky messages that are loosely related to the plot of the series as a whole. Usually, the message is too short to run for the span of the entire book, so when it reaches the end, it repeats until the book is over.
* In Creator/JohnMyersMyers ''Literature/{{Silverlock}}'', virtually every named character (except Shandon/Silverlock himself), and some unnamed ones are characters from some other work of literature. Many of the situations Silverlock finds himself in are also lifted from other works. Knowing the source works adds to the depth of the story.
* ''Literature/{{Noob}}'' has a FictionalVideoGame one. At some point, a ManChild player realizes the chronological age of a FishOutOfTemporalWater NonPlayerCharacter and starts calling her old despite her young physical age. The game has a verbal KeywordsConversation function and the narration mentions that the young woman seems offended by being called an old lady despite such a reaction having no reason to be in her programming as far as her role in the game's narrative goes.
* ''Literature/ReadyPlayerOne'': The entire plotline of the book. Multibillionaire game designer James Halliday created the OASIS, a virtual reality-based MMORPG as big as an entire universe, and it grew in popularity enough that the entire world used it not only for fun, but for careers and education. And somewhere in all of that massive amount of data, Halliday programmed an Easter Egg, locatable only with exceptional reasoning and fanatical knowledge of the '80s. Shortly after his death, the server broadcasted his last will and testament, which stated that that the first person to find the egg would inherit control of the OASIS along with his multibillion dollar fortune. And considering that this is set in a future where poverty is the norm...

[[folder:Live-Action Television]]
* ''Series/MurdochMysteries'':
** In the episode "Invention Convention", Murdoch realizes they don't need a cipher to read the random string of code -- it is actually made of substituted letters. If [[TheProducerThinksOfEverything one actually decodes the message]], it reads "It is essential that we are all seen to be watching the speech at the instant the machine fires. We have precisely twenty seconds between when the device is triggered and when the shot is fired. Should the machine be discovered it is imperative that we stick to the plan." This trope might be averted since there are a few spelling mistakes, and it almost reads as nonsense in the middle, but whoever wrote the code [[ViewersAreGeniuses was assuming the message wouldn't be read anyway.]]
** In the episode "Glory Days", there's a crate of "Big Bang" brand dynamite visible near a train that was held up, supposedly by Butch Cassidy and the Sundance Kid.

[[folder:Fine Art]]
* Some paintings have hidden images, such as Holbein's [[http://en.wikipedia.org/wiki/The_Ambassadors_(Holbein) ''The Ambassadors'']], which has a greatly distorted skull that can be seen when the painting is viewed from an extreme angle.
* After Biagio da Cesena, Master of Ceremonies to Pope Paul III, complained about the nudity in the Last Judgement panel of the Sistine Chapel, Michelangelo worked him into the painting. He is depicted as one of the damned in hell, with donkey ears and a [[DoesThisRemindYouOfAnything coiled snake]] preserving his modesty. The Pope apparently thought it was hilarious: when Cesena complained, the pope replied that [[CrowningMomentOfFunny his jurisdiction did not include Hell, so the portrait would have to remain]].

* ''Games'' magazine occasionally (most often in the [[AprilFoolsDay April issue]]) runs hidden contests, in which instructions for an item to send in are somehow hidden in the magazine.
* In the ''Magazine/DragonMagazine'' era of Phil Foglio's ''ComicStrip/WhatsNewWithPhilAndDixie'', the duo once accidentally got water on a small purple dragon that reproduced when wet, ''Film/{{Gremlins}}''-style. That entire issue of ''Dragon'' was peppered with little sketches of the dragon's offspring, gamboling in the margins or sitting on top of paragraphs saying "''Growf?''".
* ''Creator/{{Mattel}}'' did a easter egg in their ''Main/AmericanGirl'' magazines. In one of the "The World According to Aggie" comic strips, there is a hidden message written by a 11-year-old girl in Toledo, Ohio (known as "Hannah C.") which said "Follow Your Inner Star" (the official tagline of the product brand), along with the official A (Star) G logo (as these are written in invisible white ink) on one of the visible comic panels [[spoiler:because you need a flashlight to see the tagline and logo during the evening]].

* {{Hidden Track}}s are so common they have their own article.
* In the Music/AphexTwin song "Equation" there is a tone which, if you run it through a spectrograph, forms a picture of (Aphex Twin sole member) Richard D. James's face.
* Blink-182's album, ''Enema of the State'', has a hidden message in the fold. It says, in somewhat hard to spot white text, "Viking Wizard Eyes, Wizard Full of Lies."
* Synthpop band Information Society encoded text files as modem noise tracks. If you play the song "300bps N, 8, 1 (Terminal Mode or Ascii Download)" into a modem set up according to those instructions,[[note]]300 baud, No parity, 8 bits, 1 stop bit[[/note]] you will get [[http://www.textfiles.com/humor/is_story.txt this silly story]]. Do the same to "White Roses 1.0 300 8-N-1", and you will get the instructions to start an online scavenger hunt for the parts of [[http://spacemutiny.com/whiteroses/ the actual song]].
* In the liner notes in Music/TaylorSwift's albums, the lyrics are all lowercase except for a few seemingly random capital letters. When read top to bottom, the capital letters spell out a message (for instance, "Can't tell me nothin'" is the hidden message in the lyrics to "Tim [=McGraw=]").
* On WithinTemptation's Mother Earth Tour DVD, the song "Gothic Christmas" is included as an Easter egg.
* ''Music/StrongBadSingsAndOtherTypeHits'' contains a track with two songs, the first song being played normally, and the second song (aptly named "Secret Song") being played after about three or four minutes of silence.
* The liner notes to all of Music/DavidCrowderBand's album releases since ''Can You Hear Us?'' conclude with the band thanking the reader for being so patient and loving of the written word, and as a way of saying thanks they include a link to a special "Goodreader" page.
* Music/{{Radiohead}}'s ''Music/OKComputer'' has some text hidden behind the spine of the cd case. It reads "I like you. I like you. You are a wonderful person. I'm full of enthusiasm. I'm going places. I'll be happy to help you. I am an important person, would you like to come home with me". Also, early pressings of ''Music/KidA'' included a booklet full of artwork and text (some of which later turned out to be lyrics for their next album, ''Music/{{Amnesiac}}'') hidden underneath the cd tray.
* The booklet to Music/{{Weezer}}'s ''The Green Album'' folds out into a poster-sized crowd photo of one of their live performances: In the right hand corner there's the silhouettes of [[Series/MysteryScienceTheater3000 Mike Nelson, Tom Servo, and Crow T. Robot]], just barely visible because they blend into the shadows of the audience members. It's given away just a little bit because the liner notes include a copyright notice from Best Brains. Also, hidden behind the spine of the cd case of the same album is the word "No". Some fans claim it's an answer to the above ''Music/OKComputer'' easter egg, since both are hidden in the same place, but there's no confirmation of this from the band - the only official explanation (from the band's webmaster, Karl Koch) has been "no means no".
** ''Pinkerton'' has a map hidden under the CD tray labeled "Isol Della Farfalla e Penisola Di Cane" (Italian for "Island of the Butterfly and Peninsula of Dog"). Said map is full of [[ShoutOut names of people who influenced the making of the album]] ranging from [[Music/TheBeachBoys Brian Wilson]] to Creator/HowardStern.
* Music/DreamTheater's former drummer, Mike Portnoy, always liked to say "Eat my ass and balls" during live shows. Said phrase appears in Morse code in one of the band's songs, "In the Name of God".
* Mike Doughty's ''Haughty Melodic'' includes a hidden message that can be read by putting the cd in your computer, provided your computer uses Gracenote CDDB to identify track names: The song "Grey Ghost" is listed as "Grey Ghost (Here's the hidden message. Eat your greens. Read 'Everything and Nothing' by Borges. Thanks for listening. Mike)"
* Take a look at the [[FunWithAcronyms first letter of tracks 4-9]] on the soundtrack to ''Film/BatmanBegins''. [[spoiler: It spells "Batman"!]]
* Reggie And The Full Effect's ''Under The Tray'' sort of made the CD ''itself'' an easter egg: When you open the packaging up, it appears at first that you were accidentally sold an empty case. However, if you take the album title to heart and pull out the empty CD tray, you'll find the disc underneath it, along with a picture of a smiling James Dewees and the text "You found it!". Of course, many listeners didn't take the album title as a hint and complained to retailers about being ripped off. This is why there's an alternate version of the cover that adds a diagram of a CD tray being removed to the MinimalisticCoverArt.
* There is a section in Music/PinkFloyd's song "Empty Spaces" (on ''Music/TheWall'''s first CD) of [[SpokenWordInMusic what sounds like someone talking in some foreign language]]. By playing the song backwards, it becomes a hidden message from Roger, basically amounting to "[[AWinnerIsYou Congratulations, you've found the hidden message]]!"
* Music/{{Rush}}'s 2012 effort, ''Music/ClockworkAngels'', depicts [[http://assets.rollingstone.com/assets/images/album_review/159a062f516e33b400e90c3e6e86d1afe183fb46.jpg a clock on the cover]]. Assuming the normal placement of numbers on an analog clock, the hands point to 9:12. 9:12 PM, in military time, is [[CallBack 2112]].
* Creator/MontyPython released ''AudioPlay/TheMontyPythonMatchingTieAndHandkerchief'' in 1973. The single record has three sides. (Actually, one side has two interlocking spiral grooves. Getting the needle into the second groove so you could hear the "third" side could be quite tricky.)
* Music/AshleeSimpson has a hidden note about being yourself in spite of issues in the spine of the cd case.
* The initial pressing of Music/PetShopBoys' album ''Very'' was in a custom-molded, solid orange jewel case. It still had a paper tray liner (with a pattern of Chris and Neil's floating heads against an orange background) but you had to pry the tray out of the jewel case (or hold the whole thing against a light source) to see it. Unfortunately, later pressings of ''Very'' were just in a standard jewel case, with a solid pink tray liner.
* Music/{{Starflyer 59}}'s ''Ghosts of the Future'' (a boxed set of vinyl singles) had a brief bit of text etched into the runout groove of each disc. Read in order, they formed a brief poem:
-->I play guitar and also sing for those who will keep listening. And so to make them come alive, they must be played at 45.
* Toadies' ''Rubberneck'' has a photo of the group printed on the reverse of the back cover, meaning you have to remove the non-transparent CD tray to see it. It was also the only image of the band included anywhere on the album packaging.
* Music/WeirdAlYankovic did this on a few of his [=CDs=].
** The CD version of ''Off The Deep End'' has ten minutes of silence after the song You Don't Love Me Anymore, followed by screaming. Al admitted he did it to troll anyone listening and forgot to turn off their CD player.
** If ''Running With Scissors'' is played on a computer, you can go into the CD and watch an condensed version of his 1996 going home special for the Disney Channel.
** Similar to the above example, if ''Straight Outta Lynwood'' is played on the computer, you can watch Al's old home movies as he playfully riffs them. [[ThankingTheViewer He also thanks you for buying his album...]] [[DigitalPiracyIsEvil "Instead of downloading it like a HOOLIGAN!"]]

* There's a longstanding tradition in the {{Pinball}} industry of hiding references to cows as Easter Eggs in commercial games, and some players even use the term "Hidden Cows" for Easter Eggs.
** The tradition started in ''[[Pinball/TheMachineBrideOfPinbot The Machine: Bride of Pin*Bot]]'', as programmer Creator/BrianEddy likes cows. When a ball starts, hold the right flipper, left flipper, then both flippers for at least 45 seconds each. The game will beep; players can then tap out "Old [=MacDonald=] Had a Farm" with the flipper buttons (right flipper first) and the game will sing along.
** See EverythingsBetterWithCows for a more comprehensive list.
* Many [[Creator/WilliamsElectronics Bally/Williams]] pins of TheNineties have a "Midnight Madness" mode that starts when a game is in progress and the machine's internal clock reaches midnight. It was conceived by programmer Dwight Sullivan, who had a dream of seeing every game in an arcade light up with this mode at the exact same time. He added it to the games he programmed, and asked others to do the same. The most common form of Midnight Madness has the machine pretending to malfunction, the flippers go dead, and the game fakes shutting down. After a few seconds, the game wakes up, all balls are launched, and a four-ball multiball frenzy starts where every target is worth 3 million points, with each hit accompanied by various {{Written Sound Effect}}s. ''[[Pinball/WHODunnit WHO dunnit]], Pinball/{{Congo}},'' and ''Pinball/JohnnyMnemonic'' all have this, though some of them require the operator to enable the "Special Mode" setting.
* ''Pinball/StarTrekTheNextGeneration'' has several:
** The game's normal VideoMode is a shuttle simulation in the holodeck. An alternative replaces the simulation with a game of Five-Card Draw Poker against Commander Riker instead.
** Secret Mission: When the holodeck is lit on the right ramp and the display says "Holodeck 3 Ready", pull the phaser trigger three times. This starts a 20 second frenzy where every target is worth a weird number of points.
** When the ball goes in the Advance Rank[=/=]Command Decision hole when nothing is lit, pull the trigger to see a limousine drive past some buildings.
** Steve Ritchie's Pinography: Pressing the flipper buttons in a specific order during the game will display the logos of all of Steve Ritchie's past games.
* In ''Pinball/FunHouse'', Rudy gives each player a nickname at the start of each game. If a player is nicknamed "Slick", Rudy will sometimes use derogatory comments instead of his usual MadLibsDialogue.
* In ''Pinball/TalesOfTheArabianNights'', press both flipper buttons quickly when entering the Bazaar. On the fourth visit, the merchant will give you a cow worth 1 million points.
* In ''Pinball/WhiteWater'', when the Extra Ball is lit, Wet Willie will say "Get the extra ball!" However, there is a very small chance he will instead say "Get the extra ball... YA WIENER!"
* During a normal game in ''Pinball/FishTales'', various sea creatures swim by. Occasionally, a skeleton fish will appear, and mashing the "cast" button about 10 times when this happens nets you "Russ' Fishbone Bonus" - a mere 10 points.
* The "Saucer Attack" mode of ''Pinball/AttackFromMars'' can randomly become [[EverythingsBetterWithCows "Cow Attack"]] instead. The version of the mode featured in ''Pinball/JunkYard'' keeps this.
* In ''Pinball/JunkYard'' itself, hitting the TimeMachine (which is what brings up the "Saucer Attack" mode in the first place) and pressing both flipper buttons three times when it displays 3:33 starts a secret mode. WordOfGod says that going fast enough in the "Run From Spike" VideoMode plays the famous sound effect from ''Series/TheSixMillionDollarMan''. And the game also has a Midnight Madness mode, as described above.
* Combining this trope with CreatorThumbprint, veteran designer Creator/GregKmiec always includes a solid red post somewhere on his playfields. The tradition started when Creator/{{Bally}} refused to identify their designers, so he included a single plastic red post (at the time reserved for bingo games) as a way around that. More information can be found [[http://www.jeff-z.com/pinball/redpost/redpost.html here.]]
* Hitting a certain shot in ''Pinball/DoctorWho'' sometimes displays [[EverythingsBetterWithCows a cow]] in Doctor attire, mooing.
* ''Pinball/BramStokersDracula'':
** If you can get Dracula to cross his eyes and hit the Start button while he does so, an animated picture of Fluffy the Vampire appears, and the player gets 20 points.
** Entering "S-U-N" as your initials at the end of a good game prompts the screen to display "No, not the sun, arghhh!"
* Among other things, pressing a certain button combination in ''Pinball/{{Monopoly}}'' displays a paperboy with an extra edition, along with the text [[VideoGame/ZeroWing "ALL YOUR BASE]] [[MemeticMutation ARE BELONG TO US"]] (which was still fresh around the time the game was made in late 2001).
* Booting up ''Pinball/SafeCracker'' on October 24th plays a birthday greeting for two people named Amanda and Ryan.
* Several in ''Pinball/JackBot'':
** Press both flipper buttons when the wheel is spinning in Casino Run to get a Kombat Kode for ''VideoGame/MortalKombat3''. (Another Kombat Kode in ''3'' itself tells you how to do this.)
** Occasionally, the Extra Ball button flashes during AttractMode: push it to reveal the credits and the story behind the project (and a [[InMemoriam dedication]] to Joe Joos Jr.).
** Also, watch the Keno card when you get a high score and enter your initials.
* In ''Pinball/BlackRose'', it's possible to kill [[PirateParrot Polly]] by mashing the Fire button. It awards 2 million points.
* Creator/SegaPinball's ''Pinball/GoldenEye'' begins with James Bond walking in front of the display, then turning to shoot at the player. If you pull the trigger to fire first, various silly animations appear.
* The game ''Pinball/MonsterBash'' has six music tracks, one for each of the game's Franchise/UniversalHorror monsters. The seventh track, "Lyman's Lament", is normally available after the player shoots the Concert Hall scoop 44 times in a single game -- but a secret combination of flipper presses on the first ball allows it to be available immediately.
* On the attract modes of both ''Pinball/RevengeFromMars'' and ''Pinball/StarWarsEpisodeI,'' pressing the flipper buttons in a certain sequence[[note]]Left and right together, then right, left, right, right, left, right, right, right, left, and left[[/note]] will show a picture of the development team.
* The cabinet art of ''[[Pinball/LightsCameraAction Lights... Camera... Action!]]'' has the name of designer Jon Norris spelled out among the rocks.
* Several Williams/Bally games in the 1990s would feature a hidden "DOHO" in the dot matrix graphic artwork. "DOHO" was a reference to '''Do'''ris '''Ho''', the wife of former Williams/Bally display animator Scott Slomiany (AKA "Scott Matrix"). DOHO was first seen in ''Pinball/TheAddamsFamily'', the first game which Slomiany worked on.

[[folder: Tabletop Games]]
* Many cards in ''TabletopGame/MagicTheGathering'' have Easter Eggs in the name, "flavor text", or art. This is especially prevalent in gag sets like ''Unglued'' and ''Unhinged'', and in improved versions of older cards, like the "timeshifted" sets from ''Time Spiral'' and ''Planar Chaos''. (which was still fresh around the time the game was made in late 2001). [[http://www.wizards.com/Magic/Magazine/Article.aspx?x=mtgcom/feature/240 This article]] reveals some of the tiniest.
* Page 333 of the second edition ''TabletopGame/UnknownArmies'' corebook.
* In the 3.5 ''TabletopGame/DungeonsAndDragons'' sourcebook, the Expanded Psionics Handbook, the power Deja Vu (which makes someone repeat their last action) is printed twice, on opposite sides of the same page.
* ''TableTopGame/TheDresdenFiles'' RPG has PDF versions of the sourcebooks available if you buy them online; in several places where [[PaintingTheMedium Harry scratched out part of the text with Sharpie]], you can copy the text into another program and read what was underneath. But it usually turns out to be something like "by the way, if you're reading this, we sure bet you feel clever!"
** That's only part of it; the Sharpie'd out segments are in a larger article about the Christian God and his abilities, with the implication being that Harry Dresden himself blacked out the stuff because he didn't think the Heavenly Host would appreciate having that kind of information spread about them. Performing the above-mentioned trick reveals that the text says (paraphrased) [[spoiler:Their powers are unknown, but presumably have something to do with Jim Butcher's writing. It'll all be revealed in due time, so just be patient, okay?]]
** The first gamebook's section on worldbuilding, the author remarks on having significant pieces of architecture in one's city, saying "Perhaps the St. Louis Arch is a gateway to something deep in the Nevernever. Maybe the Pyramids at Giza are [[spoiler:nowhere near as bad as Chichen Itza]]." This serves as {{Foreshadowing}} to the novel ''Changes'', not yet released when the game books came out, where Harry and crew go to Chichen Itza and [[spoiler:destroy the Red Court of Vampires at the cost of Harry's lover Susan]].
** There are also a couple of jokes hidden in ''the index''. For instance, the game is split into two volumes ("Your Story" and "Our World"), so references are given as "YS" or "OW" followed by a page number. Then you come across this entry:
-->Who Is Number One?: [[Series/ThePrisoner UR#6]]
** Others include such gems as:
-->Werewolf?: ([[Film/YoungFrankenstein There, wolf. There, castle.]])
-->[[NoodleIncident Lenny's "Boxers" Story]]: see [[BrainBleach My Eyes, My Precious Precious Eyes]]
-->[[UnwantedAssistance Shut Up Bob]]: [[RunningGag YS13, YS22, YS58, YS91, YS121, YS123, YS126, YS132, YS182, YS260, YS280, YS281, YS302, OW32, OW94, OW112, OW119, OW220]]
* Almost all the card-illustrations in ''TabletopGame/IlluminatiNewWorldOrder'' slip in a stylized [[TheIlluminati Eye in the Pyramid]].
* ''TabletopGame/CardsAgainstHumanity'' has ''The Bigger, Blacker Box'', which contains the white card [[spoiler: "The biggest, blackest dick"]] hidden in the lid of the box.

* The page quote comes from ''Series/RedDwarf''. This was because, in the day when the show was made, it would have taken a lot of time, effort and specialised equipment to actually create the reversed sound-track to hear the easter egg. The show itself admitted it wasn't a very good Easter Egg, and included a live frontwards playback of it in their "Smegups" tape.
* In the ''Series/{{Heroes}}'' episode "The Fix", [[FreezeFrameBonus a quick glimpse]] at Kaito Nakamura's license plate shows that it reads "NCC-1701". George Takei, the actor who portrayed Kaito, also played Sulu in ''Franchise/StarTrek'' -- and of course, the Enterprise's registry number is NCC-1701.
* On ''TheSimpsons'', if you pause the list of “corrections” Rock Bottom wished to make in "Homer Badman", you find out you have no life.
* In the re-imagined ''Series/{{Battlestar Galactica|2003}}'', the audience can sometimes see ships in the shots of the Fleet that are {{Shout Out}}s to either the original ''Battlestar'' or other sci-fi shows. Other than numerous ships who were modeled after the original series, the show contained shots of [[Franchise/StarTrek the Enterprise]], [[Series/{{Firefly}} Serenity]], various ships from ''Series/BabylonFive'' and, of all things, the Kodiak from ''[[VideoGame/CommandAndConquer Tiberian Sun]]''.
** And a weapons locker in Season 4 was numbered "1701", another reference to ''Star Trek''.
** The show also at times made no attempt at hiding recognizable company logos on buildings in Caprica, and one early episode features a crystal clear closeup of the spines of a few of the books in Adama's cabin - revealing them to be Reader's Digest Condensed Books volumes! Eagle-eyed viewers will also see recognizable street signs and traffic lights in the Caprica scenes as well. Given the fact the series is predicated on Caprican civilization parallelling Earth's, these are more likely to be Easter eggs than accidental anachronisms.
* In one of the episodes of the German crime series 'Mord mit aussicht' you have the male policeman running through the hospital and looking awkwardly to a doctor: a doctor that also appears in another famous series: 'Lindenstrasse'
* In Season 2 of ''Series/{{Castle}}'', the episode "[[HalloweenEpisode Vampire Weekend]]" has a few {{Shout Out}}s to {{Series/Firefly}}, the television series that made Creator/NathanFillion famous.
** The easiest one to spot is the opening scene. [[Creator/NathanFillion Castle]] dons his old Browncoat for a Halloween Costume. HilarityEnsues when his daughter [[http://www.youtube.com/watch?v=3Q3pdj9p6yI spots him.]]
** However, Fillion's [[http://twitter.com/NathanFillion/status/5219538270 Twitter feed]] says that the REAL Easter Egg was the Catalyzer from the Episode "Out of Gas."
* The ''Allspark Almanacs'', the guides to the TransformersAnimated universe, are basically a gigantic easter egg hunt. They're littered not only with a million {{Shout Out}}s to other parts of the Transformers mythos, but to real life (one of the unnamed drag racers, seen in exactly one scene and never named is given the name of a voice actor's daughter) and every tangentially geeky thing from ''Series/BuffyTheVampireSlayer'' to ''Literature/{{Animorphs}}''. The stellar map in ''Allspark Almanac II'' is a particularly egregious offender, featuring hundreds of individual worlds that are ''all'' named after geek references.
* In "Brown Betty" on ''Series/{{Fringe}}'', several things allude to upcoming episodes: Walter sings "Candy man" linking to the episode "The Abducted"; the killer is removing hearts, similar to ep "Marionette".
** The glyphs (six-fingered hand, seahorse, frog, butterfly, etc.) also appear in the background of several episodes, usually in places of significance to Olivia and Peter.
* On the Nicktoon ''WesternAnimation/InvaderZim'', series creator Jhonen Vasquez secretly inserted images of GIR covered in blood in a few episodes, without Nickelodeon knowing.
* ''WesternAnimation/{{Sealab 2021}}'' frequently featured the Big Green Phone, which is surrounded by [[BathroomStallGraffiti random graffiti]]. In one episode, it appeared twice, the second time with the phrase "This graffiti is not different stop pausing" added.
* ''Series/{{NCIS}}'' occasionally pokes fun at co-star David [=McCallum's=] long career. In one early episode a publicity photograph of [=McCallum=] from ''The Man from UNCLE'' is shown as representing Ducky as a young man, and in another episode, when a character asks Gibbs what Ducky looked like as a young man, Gibbs replies "Ilya Kuryakin".
* ''Series/HillStreetBlues'' was a very low rated show in its first season, but won a large number of Emmy Awards due to its quality. In the second season opener, one of the statues is sitting on a file cabinet in the station, and Lt Henry Goldblume picks it up and carries it off without any comment as he walks through the scene.
* Lampshaded and used as a rather important plot point in the ''Series/DoctorWho'' episode ''Blink,'' in which the Doctor places Easter eggs on each DVD owned by Sally Sparrow in order to warn her about the Weeping Angels.
* In ''Series/{{Lost}}'' there are six numbers that show up constantly - 4 8 15 16 23 42. The crew had fun cramming as many references to these numbers as possible into the series, and fans had fun finding them
* ''Series/StarTrekTheNextGeneration'':
** The fifth generation of a family tree shown briefly in "The Neutral Zone" were all apparently named after the ''Series/DoctorWho'' actors William Hartnell and Patrick Troughton, Jon Pertwee and Tom Baker, and Peter Davison and Colin Baker. Imagine the weddings! Other names on the readout included [[Series/{{Mash}} Charles Winchester]], [[Series/TheMaryTylerMooreShow Louis Grant and Mary Richards]].
** Look closely at some of the equipment used by a geological survey team in the episode "Pen Pals". One of their devices is [[Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension the Oscillation Overthruster]].
** In "Peak Performance", there's a glance of a computer screen showing the plans for a battle simulation. The simulation's name is ''[[LightNovel/DirtyPair Operation: Lovely Angel]]'', and the three planets in the nearby system are called Kei, Yuri and [[Anime/MyNeighborTotoro Totoro]].
** Michael Okuda, the set designer and technical consultant who designed the signature LCARS computer monitor style on TNG, was fond of throwing in in-jokes, particularly referencing manga titles and ''Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension'', in the texts on the computer screens. Such Easter Eggs are often referred to by fans of the show as Okudagrams.
* A listing of dead crew members shown in the ''Series/StarTrekVoyager'' episode "Imperfection" reveals that most of the cast of "Series/TheWestWing" died onboard the ship.
* Jackie Gleason chose to show off his photographic memory while appearing on ''Series/TheHoneymooners'', reportedly only reading his scripts once and never taking part in rehearsals. If you ever see Ralph rubbing his belly on the show, it's actually Gleason's signal to the co-stars that he forgot a line.
* The ''WesternAnimation/SouthPark'' animators have supposedly hidden at least one alien into every episode; there are [[https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=7&cad=rja&ved=0CFwQFjAG&url=http%3A%2F%2Fwww.eeggs.com%2Fitems%2F1256.html&ei=lI1dUe-ECtL_rAGp04HQAw&usg=AFQjCNFA9NKRwNwEg3oiByIlJOB6wktzVA&sig2=sbxHyAx1yykLRNnbvTfT4w&bvm=bv.44770516,d.aWM web pages]] and [[https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&cad=rja&ved=0CEoQtwIwBA&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DAHAZBbDoGT0&ei=lI1dUe-ECtL_rAGp04HQAw&usg=AFQjCNHh5o2PR_HS2sgIgJWyoDibE6MZYg&sig2=WLm1C0UsR0wBGyQxzbC8iw&bvm=bv.44770516,d.aWM YouTube videos]] dedicated to documenting as many as possible.
* In the Creator/FUNimation dub of Manga/{{Bleach}}, when the team is confronted by a group of Adjucas (medium-high level Hollows) in Las Noches, Nel tries to use her status as an arrancar to get them to back off. She's told "All that gets you is a free cup of tea at Las Noches". There's a scene in a later episode where Aizen refuses to start a meeting with the Espada until he's certain that everyone has a cup of tea, which [[MemeticMutation has spread through the internet like wildfire]], but at the time this episode of the dub aired the only people who would have known about it are people who have seen the original airings of Bleach.
* One early aspect of ''Series/WheelOfFortune'' was its shopping rounds, in which contestants spent their money on prizes after each round. This element was retired in late 1987 (a month into the fifth season of the nighttime syndicated version[[note]]''Wheel'' began on daytime network TV in 1975, ran in both daytime and syndication from 1983-1991, and has been nighttime-only ever since[[/note]]) to speed up gameplay and lessen the tax burden on contestants, but it produced the somewhat memetic "ceramic dalmatian", an originally UndesirablePrize that later became an unofficial mascot of the show. The show has retained at least one, dubbed "Sheldon", who occasionally makes on-set appearances. Most notably, he was hidden somewhere on-set throughout ''all'' of the 30th season, as a sort of homage.
* ''Series/{{Arrow}}'' is absolutely littered with them, seeing as a lot of the people behind the scenes are massive comic-book geeks. Some are obvious (such as references to the numbers 52, ArcNumber of the DC Comics universe, or 41, the year ''Green Arrow'' debuted,) while others are pretty obscure (in one episode, Oliver is wearing a prison jumpsuit with the number 399471. This is the HTML hex code for the specific shade of green used on Green Arrow in the comics.)
* ''WesternAnimation/TotalDrama'' includes a quick one in the first season episode ''Basic Straining''. When Duncan and Courtney are raiding the fridge, the "missing boy" pictured on the milk carton is Ezekiel, the first contestant to be eliminated. Oddly enough, it's never been acknowledged who reported Ezekiel missing in the first place, or if this person ever found out where he was.
** Ezekiel can also be seen in the background of several scenes on the plane during ''World Tour'', some more obvious than others. Unlike the example above, there is a purpose to this in that [[spoiler: Ezekiel has been hiding on the plane following his elimination]].
** During ''Revenge of the Island'', a dark, [[RedEyesTakeWarning red-eyed]] figure resembling Mike can be seen in the background of one of his mind scenes. [[spoiler: This serves as foreshadowing for Mal, a character that would become much more prominent during the next season.]]
* In an episode of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', the CouchGag featured Mandy saying something in reverse. If someone were to use an audio editor to reverse the clip, you get this piece of SelfDeprecation:
--> '''Mandy:''' Cartoons will rot your brain.
** Reversing the end of the original credits, which has a reversed voice clip, gives you this:
--> '''Narrator:''' No, no, this is the end of the show! [[CaptainObvious You're watching backwards!]]

* ''Theatre/CyranoDeBergerac'': At Act II Scene VII, Count De Guiche mentions the famous scene of the windmills that appear at Literature/DonQuixote, and Cyrano mentions it’s in chapter XIII. But that scene is at chapter VIII. Any character could make a mistake... except Cyrano, who is a BrokenAce. Chapter XIII (''In which is ended the story of the shepherdess Marcela, with other incidents'') narrates the tragic tale of the love between Grisóstomo and Marcela, [[{{Arcadia}} two shepherds]], and is the deconstruction of the RomanceNovel, the genre [[FanDumb Roxane is obsessed with]]. The protagonists, Cyrano, Le Bret and Roxane are {{Expies}} of Grisóstomo, Ambrosio and Marcela, the shepherds Don Quixote meets at that chapter.
--> '''De Guiche:''' ''(who has controlled himself—smiling):''Have you read 'Don Quixote'?
--> '''Cyrano:'''I have!
--> And doff my hat at th' mad knight-errant's name.
--> '''De Guiche:''' I counsel you to study. . .
-->'''A Porter''' ''(appearing at back):''My lord's chair!
--> '''De Guiche:''' The windmill chapter!
--> '''Cyrano:''' ''(bowing):'' Chapter the Thirteenth.
* The Original Broadway Cast album for ''Film/{{Hairspray}}'' has a hidden surprise--if you leave the CD running after "You Can't Stop the Beat," the cast sings a short song called "Blood on the Pavement." It's an [[GallowsHumor upbeat ditty about finding bloody body parts on the sidewalk after a DUI.]] It also counts as a SpaceWhaleAesop, as there's ''no'' mention of the dangers of drinking and driving anywhere else in the show.

[[folder: Theme Parks]]
* This is done to such an extent at Ride/DisneyThemeParks that entire books have been written on the subject of finding them all. The so-called Hidden Mickeys are inconspicuous images of Mickey Mouse or his silhouette placed in various unexpected locations around the parks. It is also very common, when one attraction is closed and replaced with another, for the Imagineers to include an unobtrusive tribute to the old attraction in the new one.
** Hidden Mickeys aren't just limited to the parks; they appear throughout the movies as well (such as the one located in the middle of Princess Mia's tiara on a movie poster of ''Film/ThePrincessDiaries'' and also on numerous VHS, DVD (not counting the 2-DVD special edition and its' sequel) and Blu-ray Disc releases).
* There's one scene in ''Ride/TheAmazingAdventuresOfSpiderMan'' where you come across a movie theater that has a phone number on its marquee. If you dial it, you'll get a message saying that the theater is closed until Spider-Man can make the city safe again.

* ''[[http://nekothekitty.smackjeeves.com/ Neko the Kitty]]'' features a ''WheresWaldo'' style minigame. Hidden in every strip is a character named 'Bummy', a small purple hominid with prominent buttocks.
* ''SisterClaire'' is known for its hidden Easter Eggs and [[HomageShot homages]].
* The webcomic ''[[http://www.bitmapworld.com/ Bitmap World]]'' has a number of Easter Eggs hidden around the site, which can be discovered by searching for images of one of the characters, Mike.
* Trickster Mode in ''Webcomic/{{Homestuck}}''. Basically, go into any flash update before "Seer: Decend" where a controller icon is in the top right corner and press Ctrl+T. Something will always happen.
** Pay attention to the corners at the end of flash episodes. On occasion, you'll see an icon flash that leads to another flash, as in [[http://www.mspaintadventures.com/?s=6&p=002838 [S] Rose: Fast forward to now]][[note]]Links to Rose's version of [[http://www.mspaintadventures.com/?s=6&p=pony [S] Ride]][[/note]], in [[http://www.mspaintadventures.com/?s=6&p=006273 [S][A6I1] Karkat: Mental breakdown]][[note]]Links to [[http://www.mspaintadventures.com/?s=6&p=darkcage [S] Cage: Reveal plan]][[/note]], [[http://www.mspaintadventures.com/?s=6&p=006517 [S] Frigglish: Fast forward to Jaspersprite]][[note]]Links to Roxy's version of [[http://www.mspaintadventures.com/?s=6&p=pony2 [S] Ride]][[/note]], and [[http://www.mspaintadventures.com/?s=6&p=006927 [S] Terry: Fast forward to Liv]][[note]]Links to [[http://www.mspaintadventures.com/?s=6&p=darkcage2 [S] Wait, what am I supposed to do with this bunny again?]][[/note]].
** One curious Easter Egg is hidden in [[http://www.mspaintadventures.com/?s=6&p=002238 this Flash]]. Click the four small corner buttons to lock them, then click the second big button and unlock the corner buttons, and then click the third big button. [[spoiler:[[Franchise/{{Ghostbusters}} Who you gonna call?]]]]
* ''Webcomic/ChasingTheSunset'' has a magnifying glass icon that allows a high-res version of each strip to be viewed (but only in sections) without {{SpeechBubble}}s. Quite often the magnifier version will also contain a sketch or hidden message in the gutter between panels. In [[http://fantasycomic.com/index.php?p=c739 one strip]], however, the magnifier version shows a ''completely different background'' in the lower panels.[[note]] The magnified versions can't be downloaded directly, but their [=URLs=] are in the pages' source codes.[[/note]]
* ''Webcomic/EverydayHeroes'' tends to do this with musical notation. Carrie is shown playing [[http://eheroes.smackjeeves.com/comics/2080277/lesson-she-thought/ Beethoven's ''Moonlight Sonata'']] and [[http://eheroes.smackjeeves.com/comics/2111635/thats-a-good-friend-to-have/ Schubert's ''Ave Maria'']], Dr. Unpleasant's ringtone is the [[http://eheroes.smackjeeves.com/comics/2133693/ch14-13/ Imperial March]] while daughter Marilee has [[http://eheroes.smackjeeves.com/comics/2133699/ch14-17/ ''Night On Bald Mountain''.]]

* ''WebAnimation/HomestarRunner'' is well known for including Easter Eggs in cartoons on the site. In an inversion of this fact, Macromedia Central has an exclusive ''WebAnimation/HomestarRunner'' toon hidden inside.
* The {{webcomic}} ''{{Webcomic/Narbonic}}'' has an entirely separate text story, written in two-word segments, hidden in the filenames of each strip (of all places). The story continues into the DirectorsCut version.
** This pattern also appears in the follow-up comic ''{{SkinHorse}}''.
* Referenced in [[http://www.cinemabums.com/?p=307 this]] ''Webcomic/CinemaBums'' strip, released on Easter Monday. The comic's title also serves as a reference to [[Recap/DoctorWhoS29E10Blink another story]] where Easter Eggs play an important role.
* Google [[Franchise/TheHitchhikersGuideToTheGalaxy "Answer to Life, the Universe, and Everything"]]. Just do it.
** This also works on [[http://www.wolframalpha.com/ WolframAlpha]].
*** Also on Wolfram Alpha, if you input "Easter Egg" it returns "Interpretation: What are your easter eggs?" "Seek diligently and ye shall find. (In fact, you just did.)"
*** Also also on Wolfram Alpha, if you input "[[Film/PulpFiction do they speak English in What]]" it returns "Interpretation: "What" ain't no country I've ever heard of. They speak English in What?" "What? (English, [expletive deleted], do you speak it? (According to Jules, as played by Creator/SamuelLJackson, in his one-sided conversation with Brett in the 1994 film Film/PulpFiction))".
*** Someone working Wolfram Alpha really likes ''Pulp Fiction'', because if you search "Does he look like a bitch" you get "No!" as the response, which is part of the Jules/Brett conversation.
*** In addition, search "[[Film/TwoThousandOneASpaceOdyssey Open the pod bay doors]]" (with or without HAL) and it returns "I'm sorry, Dave. I'm afraid I can't do that."
*** Asking "How can entropy be reversed?" returns [[http://en.wikipedia.org/wiki/The_Last_Question "THERE IS AS YET INSUFFICIENT DATA FOR A MEANINGFUL ANSWER"]].
** Likewise, there was a time when you googled "failure" and got [[WhatDoYouMeanItsNotPolitical George W. Bush's biography]]. (Although to be fair that was less a case of an Easter Egg and more a result of Google bombing. Google may be one of the few pieces of software that allows its users to embed -- however temporarily -- their own Easter eggs in its output.)
** Very few of them work any more, but there were a number of great "I'm Feeling Lucky" Google hits involving fake 404s or search result pages, including "French military victories" which led to [[CheeseEatingSurrenderMonkeys "Do you mean 'French military defeats'?"]] and a misspelling of "Weapons of Mass Destruction" which led to a [[http://www.coxar.pwp.blueyonder.co.uk/ fake 404]] for said weapons?
** Not to mention the Chuck Norris page?
** Behold ''[[http://www.55fun.com/book.pdf 55 Fun Things To Do With Google]]''. A great many of these are classic Easter Eggs (some already mentioned here).
** The default language of Google can be set to one of several unusual choices, including Elmer Fudd, Pirate, Bork Bork Bork!, Klingon, and Hacker.
*** Or [[http://www.youtube.com/watch?v=gsv2g8BdRCo here]]. Including ''[[LeetLingo google l33t]]'' and ''[[CanisLatinicus xx-piglatin]]'' translations and an easter egg flash game.
** Googling "[[http://www.google.com/search?q=recursion recursion]]" prompts Google to ask if you meant [[ShapedLikeItself recursion]].
*** Along similar lines, Googling "anagram" prompts Google to ask if you meant "nag a ram".
** Google [[VideoGame/StarFox64 "do a barrel roll" or "Z or R twice"]] (They both give the same result). Just do it.
*** On the same line of thought, google "tilt" or "askew".
** The amount of search results given will be appropiately changed when googling for "binary", "hexadecimal" or "octal".
** Google "ZergRush". We won't spoil its effect for you, so go on.
*** For that matter, searching Google Images for "Atari Breakout". Warning: it seems to be only half-finished, as [[spoiler: the bricks do not disappear the way they should]].
** Google "[[{{Series/Seinfeld}} Festivus]]" and an aluminum pole appears on the left hand side of the results page.
** You have to get the angle exactly right, but on Google Maps Streetview, it's possible to enter the police box outside Earl's Court Tube Station. [[Series/DoctorWho It's bigger on the inside.]]
** Google "[[Franchise/StarWars a long time ago in a galaxy far far away]]" and see what happens. (This doesn't work in Firefox for some reason.)
* In Linkara's ''WebVideo/AtopTheFourthWall'' video of ''New Guardians #2'', he plays a clip of UsefulNotes/AdolfHitler giving a speech (ItMakesSenseInContext). Towards the end, there is a message that is onscreen [[FreezeFrameBonus for only a frame or two]] which says: "Yeah, I can see why Germany would want to follow this shouting, drug-crazed lunatic. ZOMG EasterEgg! [[ShoutOut Hi]] [[OneOfUs TV Tropes!]]"
* When composing a new mail in Yahoo! Mail. Pressing the text "Subject:" at the top will yield any number of random phrases that refer to either [[MemeticMutation internet memes]], [[ByThePowerOfGrayskull TV catchphrases]], or assorted inane statements.
* ''[[http://www.sandrapetit.com/name-generator.html This Name Generator]]'' contains ones for those who want male flower or gemstone names.
* In the ''WebVideo/PotterPuppetPals'' video "Trouble at Hogwarts", if the viewer freeze-frames the Avada Kedavra lightning and clicks on it when it forms a pentagram, they are taken to another short video featuring Ron and Hermione in a "follow the butterflies" skit.
* In "Ask questions" episode of ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'', if one cares to decipher the binary the Custodian is sprouting, it foreshadows series' future events, namely [[spoiler:the Ultramarines bringing Magnus back from the Eye of Terror and Cypher planning something on Mars]].
** In the same video, there's an in-joke of Alfabusa's community - ''As long as the questions don't scream about Baneblades...''
** When Magnus breaks the wards surrounding the Imperial Palace, you can briefly see "we are finally free" on the screen, a FiveSecondForeshadowing to [[ZergRush Suddenly Daemons]].
* ''Website/YouTube'':
** When a video is loading, a circle of dots will appear. Pressing arrow keys will unlock a game of Snake.
** Typing in "1980" gets you a game of ''VideoGame/MissileCommand'' in which you have to defend the video from missiles while it plays.
** If an 500 Internal Server Error occurs, part of the resulting error message that appears says, "A team of [[SelfDeprecation highly trained monkeys]] has been dispatched to deal with this situation."
** Searching "do the harlem shake" on [=YouTube=] will cause the web site ''itself'' to do it, song and all.
** Searching "[[Series/StarTrek beam me up scotty]]" will cause a brief animation where the [=YouTube=] videos "phrase into existence". Conversely, searching for "[[Franchise/StarWars use the force luke]]" will cause the page to animate as if Luke's doing exactly that on the website itself.
** Until one of the many site redesigns removed this feature, typing in the name of certain ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' characters would cause the top bar to change to that pony's coat color.
** Type the word "awesome" while the player is in focus and it will start to flash.
** The video on the Numberphile channel, on why it used to be a common glitch for [[https://www.youtube.com/watch?v=oIkhgagvrjI videos to get frozen at 301 views]], has been frozen at 301 views. This is also an example of deliberate {{irony}}.
* There are some on this very Wiki, of various levels of "supposed to be here"-ness. The page on ''Film/{{Hook}}'' is a good place to start.
%%Such as this one!
* Videos on the Glove And Boots YouTube channel where at least some of the action takes place inside Mario and Fafa's house (which is most of them) will feature a framed photo of a celebrity on the wall. Mousing over the portrait will reveal it's a link to a video that is somehow related to the person - if there's something other than a photo in the same spot, it'll usually be a link too. Sometimes they'll work additional video links in too - click on the changing posters during the montage in [[http://youtu.be/GAxJo0rWDXM time machine]] or the fake banner ads in [[http://youtu.be/D-6qN8bbRhc Your Ad Here]].
* Personal music review site [[http://www.disclaimerband.com/dmra.html Disclaimer Music Review Archive]] is set up so that reviews for artists whose names start with the same letter are all placed on one long, scrollable page in alphabetical order. At the end of an artist's reviews, there will often be a "SEE ALSO" list, which links to the author's reviews of related artists. The section for Joey Ramone only has one album review, and of course Music/TheRamones are the only related artist listed. If you click on the Ramones link despite the fact that you'd only have to do a miniscule amount of scrolling to get there manually, [[http://www.disclaimerband.com/lazy.html this happens]].
* On the website "ponyspin.com", a work-safe [[WesternAnimation/MyLittlePonyFriendshipIsMagic pony]]-version of a certain infamous ShockSite, entering the KonamiCode (substituting Enter for Start) will change the image in the center of the page from Apple Bloom to a filly version of DJ PON-3 spinning on a record.
* Typing in the Konami Code on the ''VideoGame/TeamFortress2'' Wiki will cause the Spy to sap the wiki's logo.
* If you search for Franchise/MyLittlePony on [[http://g.e-hentai.org this website]] (WARNING: VERY NSFW) , [[WesternAnimation/MyLittlePonyFriendshipIsMagic one if the characters]] will appear on top of the menu and will sport a disturbed expression on their face. [[CloudCuckoolander Pinkie Pie]] and [[{{Bookworm}} Twilight Sparkle]], however, will [[BreakingTheFourthWall look at you]] with a mischievous look.
* ''WebAnimation/SpaceTree'' includes clickable Easter eggs with buttons at end screens that are hidden until a mouseover. In one case, there was a series of secret scenes with each scene only accessible from the previous.
* ''How to Start off 2014 Right!'' by WebVideo/MatthewSantoro contains a hidden link to a bonus video.
* If you search WebSite/{{Tumblr}} for certain tags, the site will give an automated message related to it. Crosses over into CrowningMomentOfHeartwarming, since if you search for "depression" or "suicide", the site will ask if you're okay.
* ''WebAnimation/{{RWBY}}'': Each volume has a split second appearance by a [[http://vignette2.wikia.nocookie.net/rwby/images/1/1d/Over_the_rainbow!.png/revision/latest?cb=20130306201350 random velociraptor]] somewhere in the shot. The fans have dubbed him the "[=RWBYsaurus=]".
* [=RateMyProfessors.com=] has an entry for [[http://www.ratemyprofessors.com/ShowRatings.jsp?tid=230075 Ted Kaczynski]] (better known as "The Unabomber") who was, in fact, an assistant professor of mathematics at UC Berkeley between 1967-69.

* In some of the dioramas at the Denver Museum of Nature and Science, the artist painted in little elves "as a sort of signature of his work." Also, two dioramas have moving butterflies, which must freak unsuspecting visitors out. [[http://www.paleocurrents.com/docs/secrets_of_dioramas.html Here is a webpage devoted to pointing seekers to the right dioramas.]]
* Fisher & Paykel [=SmartDrive=] washing machines will turn patriotic and play God Defend New Zealand if the Power and Advance buttons are pressed together and then the Wash Temperature Up button is held down for two seconds. It is also possible for them to play Advance Australia Fair, The Star Spangled Banner, and the theme from ''Film/BeverlyHillsCop''.
* Celebrity caricaturist Al Hirschfeld was known for incorporating his daughter Nina's name into his portraits; the numeral next to his signature indicates how many times "NINA" appears in the drawing. It became such a game with his fans that Hirschfeld complained the "[=NINAs=]" were overshadowing his art. In fact, the U.S. Army used the "spot-the-NINA" game as a test of their soldiers' visual acuity.
* The vending machines used on UsefulNotes/TheLondonUnderground in the early '00s could be persuaded, by pressing a certain sequence of buttons when no credit was inserted, to display a brief test message.
* The National World War II Memorial in Washington, D.C. features a small [[http://2.bp.blogspot.com/-X19QVBa6H9o/T30RYOX6YUI/AAAAAAAAFsU/h0uaLDxUnNY/s640/kilroy.jpg "Kilroy Was Here"]] above a maintenance hatch behind the sculpture.
* The National Museum of Scotland in Edinburgh includes three dioramas showing different landscapes of ancient Scotland, from tundra to the Caledonian Pine Forest, and the wildlife that would have lived there. All three include little details that you might not notice at first, but what really belongs here is the inclusion in the tundra diorama, hidden behind the display case's frame so that you can only see it by leaning right up against the glass, of a tiny snowman.

[[folder:Real Life]]
* The TropeNamer, the easter egg. Every Easter (the first Sunday after the first full moon after the Spring Equinox) easter eggs are hidden in yards for children to find. Creative parents will often hide them in very out-of-the-way or unusual locations (up a tree, in a flower pot, etc.)

Real life Easter eggs come in three main types. Real eggs, which are hardboiled and dyed, plastic ones, which are openable to put things inside, and chocolate ones, which are... well... [[ExactlyWhatItSaysOnTheTin made of chocolate]].

%% You thought you'd find another one, didn't you? Well, you sort of did.
