** A ''[[VideoGamesSonicTheHedgehog3 Sonic & Knuckles]]'' ad in English shows screenshots of Sonic and Knuckles' respective final bosses.

** Think that's bad? Before ''VideoGame/SonicUnleashed'' was released, there was at least one trailer for EACH ZONE except the last, on BOTH versions of the game. That's bad. What's worse is this: The trailers were each around a minute long, and usually showed both day and night stages. Each zone in the Wii/[=PS2=] version (save one) has ONE primary day stage, that can be easily beaten in somewhere around three minutes (a requirement for all medals, actually). Therefore, at least a sixth of each stage was spoiled. In at least two cases, this included the GOAL RING.

** A ''Sonic & Knuckles'' ad in English shows screenshots of Sonic and Knuckles' respective final bosses.
** Metal Sonic is supposed to be the final boss of ''VideoGame/SonicHeroes'' and the secret BigBad manipulating things behind scenes, and the game and its manual treat him as a mysterious figure, refusing to call him by his true name until the final moments of the game. Despite all this, Sega of America heavily promoted the game with Metal Sonic's image.
** Elise's bio in the English website of ''VideoGame/SonicTheHedgehog2006'' gave away the fact that she has Iblis sealed inside her and would release him upon crying. In-game, this bit of information is kept a secret until the player is well into Silver's story, with the only hint given prior to that being that Eggman wants her due to her being the key to the mystery of the Flames of Disaster.

* {{Zig Zagg|ingTrope}}ed in two different trailers for ''VideoGame/ProfessorLaytonAndTheLostFuture''. One shows Future Layton's clothes being flung away as a reveal. Anyone who played the last two games would have expected it to be Don Paolo in disguise, but it's actually Doctor Stahngun/Dimitri Allen. Quickly afterwards, however, [[MasterOfDisguise Don Paolo]] reveals himself to be disguised as the ''real'' Layton. In another trailer, Layton denounces Stahngun as the villain when he discovers that he is running the future London's mafia, however, the true villain of the piece is [[ManBehindTheMan Clive]].

** ''VisualNovel/DanganronpaTriggerHappyHavoc'': Averted. The demo of the game changed the victim and killer (to Hagakure and Yamada, the two characters you'd except to die first) for the first chapter, in order to hide the first major plot twist. It was also gloriously averted when it came to Maizono: Not only is she a RomanticFalseLead in-game, but she is made out to be the female sidekick for the first chapter before dying a very sudden and shocking death a few hours in, making her the first victim. Not only did they hide her death, but all advertising material and promos for the game made Maizono out to be a major character and the main sidekick, helping to make her death even more shocking. Played straight in an English-language trailer, however, which showed Naegi escaping his execution and falling down the garbage chute. Also played straight by the game's opening movie. The movie runs every time the player starts up the game, but it shows segments of both Leon and Naegi's executions - as well as a suspicious lack of Maizono.
** ''VisualNovel/SuperDanganRonpa2'' continues this trend by mixing up the victims and killers for its demo, as well as showing clips of the game that keep characters like Togami alive.
** ''VisualNovel/NewDanganRonpaV3'' carries the torch by having a completely different demo than the game in question; Naegi and Hinata as they appear in their respective games show up, averting any spoilers for both ''1'' and ''2''. The victim is [[RunningGag Hagakure]] yet again, two of the students sit out for the trial to make room for Naegi and Hinata, and the whole thing is revealed to be [[spoiler: an elaborate ruse by the the three of them and Monokuma to get the new protagonist adjusted to what they might have to face.]]

* ''Franchise/SonicTheHedgehog'':

* The trailers for ''VideoGame/DevilMayCry 4'' gave away things like the true intentions of the Order of the Sword, the failure of an attempted ShootTheDog, and the continued importance of the demonic katana Yamato. They didn't succeed in spoiling everything, but there was something of an InternetBackdraft regarding the final trailer.

* ''Franchise/DanganRonpa'':
** Averted in the first ''VisualNovel/DanganRonpa''. The demo of the game changed the victim and killer (to Hagakure and Yamada, the two characters you'd except to die first) for the first chapter, in order to hide the first major plot twist.

* The [[https://www.youtube.com/watch?v=jMx-aS7dyPs first trailer]] for ''VideoGame/{{Sakura Wars|1996}} premiered on the Flash Sega Saturn demo disc, which came with the Saturn console back in March 1996. Towards the end, however, it spoils Sakura's ending, in which she leaves on a train and eventually leaps into Ogami's arms.

** Those who pre-ordered ''VideoGame/TalesOfSymphonia'' back in the day got an art book that, along with revealing all of the playable party members (as they were the only ones to get two pages devoted to them, along with a character synopsis,) but revealed the existence of Tethe'alla, and that Zelos is its [[TheChosenOne Chosen One.]]

* Aqua's (temporary) FaceHeelTurn in ''VideoGame/KingdomHeartsIII'' would've been shocking were it not for the trailers blatantly spoiling it.

* The final encounter with the Hive Mind in ''VideoGame/DeadSpace'' is revealed in the pre-release trailer, thus ruining a [[CrowningMomentOfAwesome potentially awesome spectacle]].

* VideoGame/SleepingDogs had a mission shown on YouTube to promote the game. Unfortunately the mission they chose was Mrs. Chu's Revenge and they even gave the spoileriffic ''name'' of the mission. Anyone who saw that video probably knew what would happen to Winston by the first fifteen minutes of the game.

** ''VideoGame/FinalFantasyXIV'' has a trailer play if you launch the game and leave it idle without logging into the server. People who own the ''Heavensward'' expansion pack are treated to a trailer where it shows a major NPC dying from a poisoned drink in the 2.5 storyline. Many fans were livid at Square-Enix for showing off a major spoiler for people who didn't reach that point in the story yet. [[spoiler: Not all is as it seems since it's revealed in the expansion pack's story that the character never died at all and was just put into a deep sleep.]]

* ''VideoGame/FinalFantasyVI'' included a map of The World of Ruin, which is what the game world turns into halfway through, with the game. It also gives away the magic system (which has some storyline significance). Not to mention listing all the characters with mini-bios (giving away a few {{Heel Face Turn}}s) and their abilities. The latter gives away the twist that Terra is a half-esper.

* ''VideoGame/FinalFantasyXIII'''s trailer has a prominent scene with all six characters flying on the back of a monster thing. Playing through the game, you get to a part where Sazh "commits suicide", but this scene hasn't happened yet. Clues you in that he's still alive! Also, he gets his summon right before that seemingly happens without giving you a chance to use it. It was shown in use in the trailers.

** ''VideoGame/FinalFantasyBraveExvius'': The 2018 Global Fan Festa spoiled the existence and appearance of two major characters Juraga and Faisalith before they were introduced to the Global version of the game proper. Also an egregious example because in a panel the day before the developers flat out did not want to spoil anything about Faisalith, not even her ''name,'' only for her to appear in the art gallery and during the orchestral performance.

* The DS remake of ''VideoGame/FinalFantasyIV'' runs into this headlong with its opening cinematic, its instruction manual, and even the back of the box. Square Enix must feel that all the info for a game approaching its twentieth birthday must qualify as ItWasHisSled.
** Then again, the instruction manual originally packaged with the North American SNES version included a walkthrough that spoiled the plot for about half of the game; just flipping through it randomly could spoil at least three {{Plotline Death}}s for you.
*** The manual spoiled even further by giving item lists that mentioned every character class in the game that could equip them. So anyone who read it over and noted that they haven't seen anyone with the class Lunarian yet could easily figure out that anything before The Giant Of Babel, the major dungeon following the recruitment of said Lunarian [[DiscOneFinalDungeon would not be the final dungeon]].

** ''VideoGame/FinalFantasyBraveExvius'': The 2018 Global Fan Festa spoiled the existence and appearance of two major characters Juraga and Faisalith before they were introduced to the Global version of the game proper.

* One of the commercials for ''VideoGame/FinalFantasyVII'' showed [[PlotlineDeath Aerith's death scene]], which probably helped cement its ItWasHisSled status. The voice-over for [[https://www.youtube.com/watch?v=Nb2qEqR7kgg&feature=related at least one of these commercials]] also said "A love that can never be." HINT HINT! Coupled with the fact that the advertisement's narration is terribly cheesy and the teaser itself is [[NeverTrustATrailer quite misleading]], this is a particularly ''egregious'' example.

* ''[[VideoGame/SuperSmashBros Super Smash Bros Brawl]]'':
** A trailer showed some icons that accidentally revealed that Ness, Jigglypuff, and Lucario were playable; all three were hidden characters in ''Brawl''.
** One of ''Brawl'''s early E3 trailers revealed that [[TheUnexpected Solid Snake]] was a playable character.
** The opening cinematic of the game blatantly shows hidden characters Marth, Ness, Snake and Sonic.
*** Arguably, this trope really doesn't apply here for Brawl - they had all been revealed on the Smash Bros. website, with the exception of Snake, long before any other trailers or cinematics were revealed.

* ''Franchise/CrashBandicoot'':

** The trailer for ''VideoGame/MetroidPrime [[UpdatedRerelease Trilogy]]'' shows the final bosses of all three ''VideoGame/MetroidPrime'' games. This could also be an example of LateArrivalSpoiler.
** Years before, one of the ads for ''VideoGame/{{Metroid}} 2: Return of Samus'' showed a clip of the fight with the final boss of the game.

* ''VideoGame/Warhammer40000SpaceMarine'' had a rather predictable reveal, a daemonic invasion headed by the chaos-infused mastermind. The trailer outright showed the protagonist fighting enemies which would only show up when something like that happened, spoiling the entire surprise. Not that GenreSavvy players wouldn't expect it.

* ''VideoGame/MaximoGhostsToGlory'' plays with it. It goes out of its way to spoil the plot twist that Sophia's Achille's DecoyDamsel for GenreSavvy players, even mentioning it in her manual bio... and naturally she's none of the above.

** Averted in the first ''VisualNovel/DanganRonpa''. The demo of the game changed the victim and killer (to Hagakure and Yamada, the two characters you'd except to die first) for the first chapter, in order to hide the first major plot twist.

Played straight in an English-language trailer, however, which showed Naegi escaping his execution and falling down the garbage chute.

* The second VideoGame/ZoneOfTheEnders intro shows you parts from the ending. If the player is wondering when certains scenes from the game are going to appear he will be spoiled.
