History Main / HolidayMode

* ''{{Tyrian}}'' prompts you if you want to play with Holiday Mode on when you start the program at the right time of year. Many sprite graphics are replaced and instead of a computer voice saying "Good Luck" at the start of a level, a different voice says "Merry Christmas".

** ''ChampionsOnline'' has a few holiday events. The most prominent is Bloodmoon which was originally for Halloween, but now happens every full moon. There's also a Christmas event, called Attack of the Misfit Toys, and April Fools Day event and an event for the anniversary of the game's release.

* In MyLittlePonyFriendshipGardens, playing on your birthday will get you a surprise letter from the ponies.

* ''{{DEFCON}}'' of all games, has a Christmas modification: the whole world is seen from a polar perspective, reindeer fly instead of bombers, the haunting soundtrack is replaced by Christmas songs, and instead of the "5 million dead" it's "5 million children made happy". That's right, you're playing as multiple factions of Santa, all struggling to deliver ''presents''. It adds a [[MoodWhiplash surreal sense of heartwarming]] to a cutthroat game of [[EndOfTheWorldAsWeKnowIt nuclear]] [[HighOctaneNightmareFuel war]].

* In ''BatmanArkhamCity'', going to see Calendar Man on certain holidays will result in him telling you a story about a crime he committed on that day. It turns into HighOctaneNightmareFuel on Mother's Day and Father's Day when he [[spoiler:tells you how he killed his mother and father on those days]]. Never said HolidayMode had to have cheery events! Doing this for all the holidays is required for the "Storyteller" achievement.

* In the independent fan-game ''SonicRoboBlast2'', the game adds hidden Easter eggs to collect around Easter time, and even keeps track permanently of which ones you collected (so if you don't get them all during one Easter time, you can finish the job the next year). During Christmas time, the game does a total visual and aural overhaul. The music for every level is replaced with a different Christmas tune, snow falls in every level, and many textures change.

* In ''{{Crusader}}'', starting the game on Christmas will result in a special bonus level where you're surrounded by a dozen of the end boss in an open room with no cover, while you're armed with every gun in the game, and a techno-industrial remix of Christmas carols plays.

* Enemies in ''KillingFloor'' get reskinned during the Christmas, Halloween and summer periods. (If you want to know, the summer theme is "circus freaks".)

* Starting October 29th and ending November 2nd, Valve released a Halloween pack for ''VideoGame/TeamFortress2'', which included a new Community Map, two new (achievment based) hats, one of which can be worn past the event, and five achievments. They also made it so that secondary and melee taunts make characters do part of the dance from the music video for ''Thriller''.

* [[AngryBirds ''Angry Birds Seasons'']]

* [[{{Pokemon}} Trainers in Sinnoh]] can enjoy Diamond Dust weather instead of snow at Snowpoint City on several notable days, including certain holidays and developer Junichi Masuda's birthday on January 12.

* ''Team Fortress'' had a party mode which could be activated by the server operator and gave all the characters party hats, changed grenades into gifts, and altered all the death announcements to fit the theme. ''TeamFortress2'' does the same thing, but sets it to automatically kick on to celebrate the week that the original game was released.

** ''[[PokemonDiamondAndPearl Pokémon Diamond, Pearl, and Platinum]]'' do this as well. Only you don't get anything out of it. On your birthday, by talking to Lucas or Dawn (depending on who you're playing as), they'll acknowledge the fact that it's your birthday and congratulate you.
