''Attack of the Mutant'' is a 1997 PC game based on the ''Literature/{{Goosebumps}}'' novel and television episode of the same name. However, the game has more characters and an extended as well as different plot.

You play as an unnamed and genderless SilentProtagonist who gets off the bus at a stop they didn't want to. Turns out this stop is the headquarters of the infamous supervillain, the Masked Mutant, who can transform into anything and anyone. The protagonist teams up with the League of Good Guys, a team of superheroes, to stop the Mutant's plot to take over the world. However, along the way, you'll have to deal with quite a few [[AxCrazy insane]] supervillains...and then there's the [[BigBad Mutant himself]]...

Like ''VideoGame/EscapeFromHorrorland'' before it, the game actually has quite a few scares and surprises ([[DefangedHorrors at least for children]]) and two different endings. Despite this, it also has some LighterAndSofter moments; making for a bit of MoodWhiplash. Also notable for being one of the first video games to use [[CelShading cel-shaded]] animation. Also, Creator/AdamWest plays the Galloping Gazelle, leader of the League of Good Guys.

----
!!This game provides examples of:
* AndIMustScream: The Masked Mutant has turned people, including children, into [[spoiler:two-dimensional comic book style cutouts...not dead, but incapable of doing anything again]].
* AdaptationalHeroism:
** The Galloping Gazelle was already a hero, but unlike the TV show, he doesn't completely abandon the protagonist once things go pear shaped for him.
** The Magnificent Molecule Man. In the book, he was a lackey for the Mutant, much like in the game. However, he did not have a HeelFaceTurn in the book like in the game.
* AxCrazy: Most of the villains have this to some extent, but special mention goes to Pinky Flamingo and the Mutant himself at times.
* BeautyEqualsGoodness: Dinah and Flo are both noticeably more attractive than Chinchilla.
* CelShading: One of the first examples of it in a video game. It makes sense, given that the game is supposed to take place in a comic book world.
* CombatPragmatist: Being one is necessary to survive in the game.
* DistressedDude[=/=]DamselInDistress: Happens to some of the League of Good Guys.
* DownerEnding: [[spoiler: If Mutant wins, the world is reduced to a desert, and the League of Good Guys iconic items are left in disrepair, as Mutant taunts you. You get this ending by failing to stop the Masked Mutant's plot in time.]]
* TheDragon: Chinchilla is apparently this for the Masked Mutant. Surprisingly, the Mutant explicitly states he chose her over the Magnificent Molecule Man because she was more loyal despite not being as powerful.
* DynamicLoading: The cutscenes of opening a door appear to be loading screens for the rooms and hallways.
* TheFaceless: You only see the character's hands unless you [[GottaCatchEmAll collect all the costume pieces]], and even then the figure is somewhat androgynous and only seen briefly.
* FanDisservice: No one needed to see a pin-up calendar of Chinchilla in the printing room.
* ForcedTransformation: The Mutant is doing this to both landmarks and people, turned them into [[spoiler:two-dimensional comic book style cutouts...not dead, but incapable of doing anything again]].
* GenreShift: It's part of the ''Goosebumps'' series, but it seems to have a lot more in common with the traditional superhero genre.
* GoldenEnding: Get this by completing the game and [[spoiler:not failing the TimedMission at the end]]. You can add a brief extra scene by getting all the costume pieces.
* GottaCatchEmAll: You can collect your own superhero costume pieces to get an extended version of the GoldenEnding, where you finally see the main character and in their costume.
* HeelFaceTurn: [[spoiler:Magnificent Molecule Man]]
* ItsAWonderfulFailure: Fail the last part of the game and see [[spoiler:what happens to the world]].
* KillItWithIce: Chinchilla in a nutshell along with being AxCrazy to a degree.
* LiteralMetaphor:
** To get the League to trust him, Magnificent Molecule Man gives you his "WORD", a card with the word "WORD" written on it. [[spoiler: Justified, since it's the password to get to Mutant's Green Beam]].
** [[spoiler: The target you have to aim for at the end is the eye of a bull emblem.]]
* MoodWhiplash: Happens when you go from being praised for your accomplishments or hearing how awesome you are from superheroes to being chased by supervillains or put in life-threatening situations.
* NiceJobBreakingItHero: [[spoiler:You help further the Mutant's plans by bringing things he needs to "Captain Bob"...AKA the Mutant.]]
* NotHelpingYourCase: The Magnificent Molecule Man apparently thought kidnapping Chinchilla, who was chosen to be the Masked Mutant's second in command, in order to prove ''he'' was more worthy of being the Mutant's righthand man, was a good idea.
* PlantPerson: Root Rot.
* ThePowerOfRock: Feedback uses an electric guitar as his primary weapon. [[spoiler: You also get to use it the final part of the game.]]
* PragmaticVillainy: The Masked Mutant made it a point to choose Chinchilla as TheDragon because she showed more loyalty to him, overlooking that she's not as strong as the Magnificent Molecule Man. What good is having a powerful second in command if they've not proven their loyalty?
* PsychopathicManchild: The Mutant. Particularly in the Bad Ending, when he taunts the player by yelling "LOSER, LOSER! WINNER, WINNER!"
* RememberTheNewGuy: Captain Bob shows shades of this in-universe-- he's not present in the comic book in the intro and yet implicates that he's been with the League of Good Guys for some time. [[spoiler: He's actually the Mutant in disguise.]]
* RealityWarper: Pinky Flamingo is able to erase different objects and characters. He can also create a batch of slowsand, and turned the Galloping Gazelle into a painting.
* SilentProtagonist: Your character never talks.
* SparedByTheAdaptation: The Magnificent Molecule Man was killed off in the book, but he survives just fine in the game.
* SpotTheImpostor: [[spoiler:Happens near the end, between Dinah and the Mutant.]]
* StealthPun: Flo's cousin Brooke, who lives in a pond and talks a lot-- essentially a "babbling Brooke".
* SuperSpeed: The Galloping Gazelle, and to some degree, Dinah.
* TakeOverTheWorld: The Mutant wants to do this by [[spoiler:turning the world into a comic book he rules over]].
* TimedMission: The finale of the game has this and [[spoiler:failing to finish in time gives you the DownerEnding]].
* TruerToTheText: The game includes The Magnificent Molecule Man, who wasn't in the TV episode.
* VideoGameCrueltyPotential: [[spoiler: You can kill the Toadies in one of the final levels, even though they are innocent characters just doing their job.]]
* VisualPun: The target you aim for at the end is [[LiteralMetaphor literally]] a emblem of a bull's eye.
* VoluntaryShapeshifting: The Mutant's power.
* WeaksauceWeakness: Feedback's weakness is easy-listening music.
-->'''Feedback:''' Listen, man, if I gotta hear anymore of this ''oatmeal music'', I'll be totally brain-dead! From the neck up!
