* Early promotion material for ''[[VideoGame/HalfLife2 Half-Life 2: Episode Two]]'' revealed that Alyx dies, or at the very least gets incapacitated, although it's also avoided in that Alyx also gets better and her "death" (falling off a bridge in the promo) is totally different in-game. The trailer also reveals that the G-Man is back in a speaking role after being sidelined for the last game.
** The reveal trailer for ''VideoGame/HalfLifeAlyx'' features Eli's "Close your eyes, honey!" line from ''Episode Two'' re-recorded with his new voice actor, Creator/JamesMosesBlack, all but spoiling the inclusion of the respective scene from that game.

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

* Trailers for ''VideoGame/Persona5'' ''[[UpdatedRerelease Royal]]'' spoil the fact that Crow returns to the party after his stint as a GuestStarPartyMember, presumably for good.

* Early promotion material for ''[[VideoGame/HalfLife2 Half Life 2: Episode 2]]'' revealed that Alyx dies, or at the very least gets incapacitated, although it's also avoided in that Alyx also gets better and her "death" (falling off a bridge in the promo) is totally different in-game. The trailer also reveals that the G-Man is back in a speaking role after being sidelined for the last game.

* 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.

* An interesting take on this trope: In ''VideoGame/SuperSmashBrosUltimate'', the character of Dharkon was kept a secret throughout development, even after his mortal enemy Galeem was revealed... But then he was shown in the trailer for [[VideoGame/DragonQuest Hero]]. Granted, that game out after the game had been released and his identity was found out, but those who haven't gotten the game yet might not know who he is.

* The ''VideoGame/{{Shantae}}'' series had a case where trailers for one unreleased game spoiled another unreleased game. A year before ''VideoGame/{{Shantae}} and the Pirate's Curse'' came out, Creator/WayForwardTechnologies began a Website/{{Kickstarter}} for the next game in the series, ''Shantae: Half-Genie Hero''. If the title wasn't enough of a clue, the accompanying promotional video pretty much confirmed that, yes, Shantae will manage to get her magic back by the end of ''Pirate's Curse''.

* The launch trailer for the 3DS UpdatedRerelease of ''VideoGame/XenobladeChronicles'' contains a lot of late-game spoilers in a rapid montage towards the end. Thankfully, it's nice enough to warn you at the start of the video that it "contains scenes that may be considered spoilers".

* The website for ''VideoGame/PuyoPuyo Tetris'' obscures the final character, Ex on the character page, but the wallpapers and Twitter icons both show Ex's appearance prominently, however, his name is not given anywhere on the site. The English website though borders on LateArrivalSpoiler, in that it actually gives him a full profile(!), but keeps the shadowed appearance, while the Japanese site just used question marks.

* ''VideoGame/MyChildLebensborn'': In the trailer, one of the scenes showing Klaus being ostracized is a man in robes skipping him while giving out hosties in a church. While acting as the adoptive parent to Klaus or his female counterpart Karin in the game proper, the only time the player actually interacts with a church official is when asking a vicar's help while trying to get in contact with the child's biological family. The vicar refuses to help, which is in tune with what is seen in the trailer.

* Divisive though it is among gameplay critics, there's little doubt that the developers of ''StarWars: VideoGame/TheForceUnleashed'' wanted the Apprentice Force-pulling a Star Destroyer out of orbit to be a significant point in the story. Not only was it depicted on the back of the box, it was also used for giant promotional posters designed specifically to be positioned at the entrance to game shops.

** It's almost impossible to be a huge ''Franchise/{{Pokemon}}'' fan and not know what the new starters and box legendaries are going to be beforehand.

** The back of the American [[VideoGame/SonicTheHedgehogCD Sonic CD]] box art shows the game's last two bosses and the last special stage.

* Several previews also spoiled the big twist in ''[[VideoGame/{{STALKER}} S.T.A.L.K.E.R.]]'' on who the player character is.

* An interesting take on this trope: In ''VideoGame/SuperSmashBrosUltimate'', the character of Dharkon was kept a secret throughout development, even after his mortal enemy Galeem was revealed... But then he was shown in the trailer for [[Franchise/DragonQuest Hero]]. Granted, that game out after the game had been released and his identity was found out, but those who haven’t gotten the game yet might not know who he is.

* ''VideoGame/{{Fallout 2}}'': A screenshot on GOG.com show how Vault 13 has been taken over by intelligent Deathclaws. And also Frank Horrigan, but at least without context.

** 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.

** A ''[[VideoGame/SonicTheHedgehog3 Sonic & Knuckles]]'' ad in English shows screenshots of Sonic and Knuckles' respective final bosses.

** While not trailer-related, Sega of America is a huge offender when it comes to media and ads related to Sonic games. The American manual of ''VideoGame/SonicTheHedgehog2'' has the story, but when you turn the page... ''BAM!'' The second picture shows a snapshot of the start of the final boss of the entire game. If you read the manual before turning on the game, good luck getting to it. The App Store page for the 2013 remake is just as bad about it, as [[http://a1.mzstatic.com/us/r30/Purple/v4/e4/5a/63/e45a63fb-7a72-b069-3049-4ae45668e214/screen568x568.jpeg the screenshot advertising the Boss Attack mode]] showed the ''exact same boss''.
** American ''Sonic'' manuals tend to have lists of all of the game's levels (even the secret final ones that must be unlocked), with screenshots and descriptions.

* The trailer for ''VideoGame/{{Nier}}'', which also plays from the title screen, ''starts off'' by stating that the game takes place 1300 years in the future, while Kaine shouts at Weiss to snap out of his brainwashing by the Shadowlord - namedropping a character that isn't even known to exist for the first half of the game. It then goes on to show the lab beneath Emil's manor and experiment No.7, Kaine being impaled and possessed, Devola preparing to attack the player...all of which otherwise come [[WhamEpisode totally out of left field]] in the plot itself.

* ''[[VideoGame/LifeIsStrange2]]'' had a whole [[https://www.youtube.com/watch?v=XPpzm08JvRg gameplay trailer]] which was a playthrough of almost the entire prologue (a few scenes and many interactions were cut out/ignored). The spoiler comes from the fact that the death of Sean and Daniel's father Esteban Diaz was shown at the very end of the video. Hell, his death is even spoiled in the plot summary for the game. Granted, it would be pretty hard ''not'' to spoil his death considering that's the driving force of the plot, especially with the game's episodic nature often having to spoil previous episodes in order to recap them, but it's still possible.

* An interesting take on this trope: In ''VideoGame/SuperSmashBrosUltimate'', the character of Dharkon was kept a secret throughout development even after his mortal enemy Galeem was revealed... But then he was shown in the trailer for the Hero DLC pack. Granted, that game out after the game had been released and his identity was found out, but those who haven’t gotten the game yet might not know who he is.
