The trailer for the Dot Hack GU games revealed exactly who the eight Epitaph Users are and which Avatars they have.
TimeSplitters: Future Perfect deserves a special mention; if you can't do a puzzle in an early level, go to the main menu, wait for the game to go into Attract Mode and watch a character do it for you. It is a very easy puzzle, admittedly, but still.
Some would argue that being a spoiler, considering the existence of the Excellence Eternal, the Mid-Season Upgrade that only she uses, in Super Robot Wars R.
In actuality, the whole bonus segment in Original Generations were like an interactive trailer for Super Robot Wars Original Generation Gaiden, thus the main story of the bonus sections got carried over to the Gaiden. Including the death of Lamia Loveless. Her rebirth in different circumstances was still well hidden in the commercial videos. As well as the inclusion of the Cry Wolves of the MX series and the returnand redemption of both Axel Almer and Alfimi.
The trailers for Devil May Cry 4 gave away things like the true intentions of the Order of the Sword, the failure of an attempted Shoot the Dog, and the continued importance of the demonic katana Yamato. They didn't succeed in spoiling everything, but there was something of an Internet Backdraft regarding the final trailer.
Several previews also spoiled the big twist in S.T.A.L.K.E.R. on who the player character is.
Multiple previews for Ratchet & Clank: Going Commando had the amazing distinction of spoiling half the game's plot, including the thief's real name and gender (which you learn halfway through the game) and the purpose of the "experiment" (not referenced in-game until just before the final boss battle).
For the third game, the true nature of Dr Nefarious' plan and the literal mechanisation of the entire Tyrrhanoid race were similarly spoilt. These things are explained around halfway and two thirds of the way into the game, respectively.
Fire Emblem Radiant Dawn is notable for having a press release that basically outlined the entire game's plot. This included the revealing of the true identity of the Black Knight, which was never revealed in the previous game Path of Radiance, but also only revealed near the end of Radiant Dawn.
The first official English trailer for Fire Emblem Fates contains rapid-fire clips from Ryoma and Xander's fight cutscenes, heavily implies something bad will happen to Mikoto (showing a scene of a dark explosion and Sakura screaming "Mother!") and that Elise will die on at least one path. True enough, the clip shown turned out to be from Elise's death scene on Birthright.
Although it's so disjointed that it may not be recognizable until you actually play it, the in-game trailer to Zone of the Enders: The 2nd Runner pretty much shows the entire game, every stage, every boss fight (with the exception of the Final Boss). It also shows pretty much the entire story, including clips from the Ending.
The trailer for Starcraft's Expansion Pack, which features several clips of a military funeral interspliced between the imagery of awesome carnage. The fact that the coffin had the banner of the United Earth Directorate on it meant that a major UED character was going to die, though it didn't become clear until the second-to-the-last Terran mission.
The manual for Neverwinter Nights 2: Mask of the Betrayer advises you to read certain pages only after you've seen the twist at the end of act one. This would have been useful advice if the Spirit Eater curse hadn't featured so prominently in the game's prerelease hype.
The base game did a decent job faking you out for the first two acts that the warlock you keep running into is either the King of Shadows or yet another one of his minions since Ammon Jerro is believed to be long dead and he attacks every other faction. It also has the mystery of the silver shards, one of which is embedded in the PC's chest, in the first act. Too bad the trailer (reused as the intro movie no less) showed the two fighting each other in your home village and a Githyanki silver sword exploding at the end of it.
The DS remake of Final Fantasy IV 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 It Was His Sled.
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 Deaths 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 would not be the final dungeon.
In Time Hollow, you get a fleeting 'flashback' of someone falling past the top of a window, and from your perspective all you can tell is that the person's probably female and a student at the high school. Unless you watched the opening trailer, in which case you know who it is right off the bat, making it painful whenever Ethan recalls it and thinks "GEE I WONDER WHO THAT WAS."
The blurb on the back of the case for Rondo of Swords spoils that you're actually playing the prince's body double, not the prince himself. This isn't as huge a spoiler as it sounds — it's revealed after the very first stage — but the game was very obviously written with the intention of keeping it a secret until this (early) reveal.
Referenced in Phoenix Wright: Ace Attorney: Trials And Tribulations, Godot mentions he doesn't like spoiling himself with trailers, and "we'll just wait and see how the movie turns out tomorrow, won't we?" when he refuses to reveal something until the trial starts.
Ace Attorney Investigations 2 would later play this straight. The trailers make a big deal of Edgeworth being offered to become a defense attorney. But the actual offer itself, coming at the end of case 2, is a majorWham Line if you don't see it coming. It's even spoiled at the end of the demo too. (In fact, though the demo comprises of basically the first half of Case 1, the exchange at the end doesn't take place until the end of Case 3)
Most trailers for Ace Attorney games blatantly give away the culprit of the game's first case. Though in some cases, the case turns out to be a Reverse Whodunnit anyway, and even when they aren't the first culprit is often a Warmup Boss and thus made completley obvious within the game itself.
The instruction manual for Totally Rad reveals master magician Zebediah's secret at least three times until they actually lampshade this trope.
One of the plot twists in Jak II: Renegade that couldn't be seen coming three miles away is that the game is set in the future. Unless you watched any trailer, of course, where it's explicitly stated by the characters.
When The Twin Snakes, the Metal Gear Solid remake for the Nintendo GameCube, was wrapping up production, several trailers were released spoiling the gene storyline (ingame, no mention of it is made until near the end) and dropping an extremely obvious hint as to who the Ninja was by playing a later clip over his introductory scene.
Ninja: Do you remember me now?
Snake: It can't be... you were killed in Zanzibar Land...
Not to mention Snake being tricked into activating Metal Gear by accident.
Terminal: PAL code number three confirmed. PAL code entry complete. Detonation code activated.
Also similar to the above Phantom Menace and Gundam SEED examples above, Metal Gear 2: Solid Snake features a track labeled "Natasha's Death" (Gustava Heffner in the re-relased versions).
Konami went to great lengths to keep Raiden a secret until the release of Metal Gear Solid 2. Unfortunately, even that wasn't enough to get around different release dates and almost every British gaming magazine which ran a story on the game that featured that. In an amusing inversion, however, many magazines were able to avoid spoiling the plot by making out that Snake had died on the Tanker, something the supporting characters treat as correct until halfway through.
The instruction manual also spells out that there will be a part of the game where you play as someone named Raiden who defuses bombs and uses a sword (it gives the controls for both). Although gamers reading it might assume that this will be a small part of the game, not the majority. But by the time The Essential Collection for PS2 came out, everyone knew about Raiden, so the manual for Metal Gear Solid 2 mentions that you will be playing as Raiden for the majority.
In Metal Gear Solid 4, the Metal Gears themselves don't play much of a role until Act 4. Screenshots showed Snake in the cockpit of a reactivated, railgun-less REX and RAY in a snow-covered harbour. There's not much of their relevance to the plot that isn't spoilt by those facts.
Think that's bad? Before Sonic Unleashed 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.
Sonic Generations was also bad about this. For a game all about reliving Sonic's history, they revealed literally every stage, boss, and rival in the game except for the final boss (the only one not to be from a previous game) in the trailers leading up to release.
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 Sonic the Hedgehog 2 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 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.
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 Sonic Heroes and the secret Big Bad 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 Sonic the Hedgehog (2006) 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.
The third anime special note not actually a trailer, but still a preview, released around the same time as Explorers of Sky, reveals that the hero, Grovyle, and Dusknoir are from the future, and that the hero will erase himself from the timeline to stop Primal Dialga.
It's almost impossible to be a huge Pokémon fan and not know what the new starters and box legendaries are going to be beforehand.
Pokémon Sun and Moon's website lists 99% of every new Pokémon, Alolan Form and Ultra Beast (even Necrozma, though they don't name or describe it). The only one that doesn't get listed is Cosmoem, which is a Walking Spoiler by itself. The trailers also gave away the return of past characters like Cynthia, Wally, Red and Blue at the Battle Tree; something the player's never told of until the main story is over.
Take the standard trailer here. Pretty much half the late game gets given away, and the Gamespot trailer actually goes further by showing even more. For that matter, one of the pre order sleeves for the game actually had a picture of the final battle on the front...
Taken even further for Wind Waker HD, which not only has a big picture of the final boss battle on the cover (in the special edition version), but also a free figurine of said boss which you can clearly see in the packaging.
Early promotion material for 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.
Quake IV has a twist where your character is captured midway through the game and turned into one of the bad guys. This would have been surprising if the press releases, trailers, and the back of the box didn't give it away.
Final Fantasy XIII'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.
Final Fantasy VI 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 Turns) and their abilities. The latter gives away the twist that Terra is a half-esper.
Shenmue's trailer spoils that Lan Di is seeking the mirrors' power, as well as an incident late in the game in which Nozomi gets kidnapped by Terry's gang.
Shadow of the Colossus had a trailer that ends with a montage showing Lord Emon looking around the shrine of worship, Mono sitting up from her resting place, and Wander lying on the ground with HORNS! Of course the last part goes by extremely quick, but keen eyed viewers of the trailer either had an idea of what the ending was about, or at least got an early head start on how the game would tie into ICO (which before the game's release, was said to have no connection to the latter title).
In a possible attempt to subvert this trope, the E3 reveal trailer for Assassin's Creed: Brotherhood featured an attack on the Papal carriage in 1503 Rome, the city and year in which Pope Alexander VI, aka Rodrigo Borgia, died. While both hold true in the game, unfortunately the circumstances are far less epic than the trailer implied.
Played more straight with some European versions of the "Story" trailer (narrated by Cesare Borgia), which concludes with a showdown between him and Ezio Auditore atop a castle wall. The US version does not name it, but the European versions identify the setting as 1507 Spain, the year and country in which Cesare Borgia died in Real Life, de facto confirmed when the developers started name-dropping the site as Viana no less. Moreover, this showdown was much more accurate to the actual in-game event than the (completely inaccurate) E3 reveal trailer had been.
Divisive though it is among gameplay critics, there's little doubt that the developers of Star Wars: The Force Unleashed 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.
Zig Zagged in two different trailers for Professor Layton and the Lost Future. 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, 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 Clive.
Mass Effect 2's previews, especially its "Fight for the Lost" campaign, gave away several plot points that the game's writers appear to have intended to be surprising reveals. Jack's sex and Archangel's identity are kept secret in-game until Shepard actually meets them, and the recruitment dossier sets Shepard up to recruit Okeer instead of Grunt; unfortunately, all three characters were featured heavily in the game's marketing, with Jack and Grunt even having their own interview-style promotional videos. And of course, the only way to somehow avoid knowing that Shepard is dead and the Normandy was destroyed at the beginning of the game would have been to avoid every piece of media BioWare released at the time of the game's development.
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 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.
Resident Evil 5 had fans upset about Jill Valentine being killed prior to the story. One of the trailers had Albert Wesker removing the hood off one of his goons claiming it to be "One big family reunion", making it obvious who it was.
Trailers for Portal 2 clearly spoiled the fact that GLaDOS was still alive and would still be the main antagonist of the game. At least for half of it.
Though, it's only a spoiler if you didn't believe the song at the end of the first Portal, Still Alive.
Extremely blatant in the case of Kid Icarus: Uprising. The information and trailers released prior to the game show off pretty much every stage, boss, character, and plot point up to Pit's final battle against Medusa. In addition, less than a month after the game's release, several new trailers came out, spoiling just about everything else.
Averted in Uncharted 3: Drake's Deception with Charlie Cutter. In the trailers before the launch, Cutter is seemingly a thug for the main antagonist and they even continue this ruse into their one month multiplayer trial, where Cutter's Skin was a part of the Villains team. In the actual game, it turns out that Cutter was always a double agent; a fact that the heroes knew before the player, and his multiplayer skin is apart of the Heroes team.. However, it's played straight in the launch trailer, released a few days before launch, where it shows Cutter planning alongside the heroes.
When City of Heroes began their Signature Story Arc program, the very first one is "Who Will Die!?" It was pretty blatant that Statesmen was going to bite it, not only because many promotional images showed his iconic faceplate laying discarded, but because the dev whose moniker was Statesmen jumped ship when Paragon Studios split from Cryptic. Averted, whoever, in that he wasn't the only one...
Thoroughly averted by Virtue's Last Reward. Though a promotional anime was released before the game, detailing the backgrounds of the characters and the setup of the Nonary Game, it neatly manages to hide the single biggest plot twist in the game. It shows Sigma's face.
Sleeping Dogs 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.
A trailer for the game included Wei mentioning that he was now one of the Red Poles.
The second Zone of the Enders 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.
Warhammer 40,000: Space Marine 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 Genre Savvy players wouldn't expect it.
Subverted Trope with regards to Inquisitor Drogan, shown in a pre-release trailer with him walking freely among Bloodletter demons, meeting 40K fans' expectations he'd be a Token Evil Teammate as Inquisitors are apt to be. Not entirely true, so the trailer didn't spoil that he's actually totally dead at all points in gameplay, and his actions in gameplay were done by a demon possessing his corpse.
Not a trailer, but a preview nonetheless of Cave Story's DSiWare port in Nintendo Power casually mentions that you play as a character named Quote, something that you should only learn late in the game if you fulfilled the complex conditions needed to obtain the Golden Ending.
Those who pre-ordered Tales of Symphonia 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 Chosen One.
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 Romantic False Lead 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 which showed Naegi escaping his execution and falling down the garbage chute.
The "Neon Reveal" trailer for inFAMOUS: Second Son, as you'd expect, reveals the identity of the holder of Delsin's Neon ability: Abigail "Fetch" Walker. Fast-forward to the game's release day and the fact that the mission in which you first meet her surrounds her with mystery regarding her gender - such as running far too fast for Delsin's current abilities to reliably keep up with and having the news portray her as a sniper perpetually at a distance - becomes utterly irrelevant.
At E3 2014, a trailer for a PS4 Updated Re-release of The Last of Us was shown, which at least had the decency to start off with a black screen showing the words "The following trailer contains spoilers".
The original trailer for Deus Ex spoiled one of the biggest twists in the game, via a cutscene of UNATCO agent Anna Navarre telling you that she "came to watch you die" (which occurs after you've been captured by UNATCO and if she's alive), as well as fellow agent Gunther Hermann trying to kill the player character, JC Denton.
The website and promotional material to Baldur's Gate 2: Throne of Bhaal made frequent referrals to Demogorgon, Prince of Demons, and his importance in the expansion pack's Watcher's Keep dungeon. Que the actual game where you're sent in there to deal with someone called the 'Imprisoned One', with the game dancing around the actual identity of the entity until you actually decide to pick a fight with it.
Similarly, the twist of the Player Character's heritage, which was only revealed in the second-to-last chapter of the original game and put the entire narrative in a very different context, is common knowledge from the second game onwards. The introduction says it outright (and all but spoils Imoen's nature as well by making her almost as central as yourself), and in-game it gets so bad that CHARNAME may as well have a giant neon sign saying 'bhaalspawn' bolted to his/her helmet.
One of the trailers for Far Cry 4 includes a shot of Pagan Min leaning against a door and talking to the protagonist through a doorframe, saying "Damn if it isn't fun." Well, this shot takes place during the game's ending. The doorframe in question is the door to the Lakshmana shrine, the place Ajay spends the entire game searching for.
The teaser trailer for The Second Reality Project 2: Zycloboo's Challenge revealed that Zycloboo had kidnapped Princess Peach and the Yoshi eggs. The remakecounterpartAverts this, since this scene and the one for the Cursed Fountain level were replaced with different scenes. In the remake itself, Lemmy Koopa, who had allied himself with Zycloboo by that point, appears in place of Peach and the eggs, and you have to fight him at the end of the level.
One trailer for Citizens of Earth, which seems to have been deleted from Atlus's Youtube channel, showed the party screen with every citizen unlocked, including two spoiler characters, the Alien and Photon. Another trailer makes things better by having a few characters still locked, but the Photon is still visible.
Shin Megami Tensei IV attempts to play up the discovery of Tokyo as a Wham Episode, but anyone who's checked out the trailers will already know of its existence. Although, why Tokyo exists in what is apparently the 15th century is another story altogether.
The followup Shin Megami Tensei IV: Apocalypse does something similar with streams showing of the game ends up spoiling YHVH's presence in the story, but like with the game before it, the real spoiler is in the details surrounding it.
The launch trailer for the 3DS Updated Re-release of Xenoblade Chronicles 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".
A main quest in Dragon Age: Inquisition involves Varric contacting an old friend who might know about the Big Bad. The game plays up the reveal as a surprise, which it could have been to anyone who didn't see the trailer that prominently featured an appearance fromHawke.
The Shantae series had a case where trailers for one unreleased game spoiled another unreleased game. A year before Shantae and the Pirate's Curse came out, WayForward Technologies began a 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 trailer for 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 totally out of left field in the plot itself.
Averted for Virtue's Last Reward which has an OVA available as promotion which shows all the players gathered in the Warehouse A room and doesn't spoil the twist that Sigma is a 22-year old college student in the body of a 67-year old man.
