->''Doom actually '''does''' teach you how to eat cereal! At least according to General Mills.''

''Chex Quest'' is a 1996 GameMod for ''VideoGame/{{Doom}}'', originally shipped in six million boxes of General Mills brand cereals. The game itself was notable for being the first CD game to be bundled in cereal boxes as a prize. The first game involves the Chex Warrior going down to a colonized planet invaded by a race of aliens called the Flemoids, on a mission to rescue the inhabitants.

In 1997, ''Chex Quest 2'' was released, but instead of being shipped with breakfast cereals, this time it was distributed exclusively on the Chex Quest website. Numerous fansites still distribute the game to this day.

There were rumors of an impending ''Chex Quest 3'', but no such thing ever came to light... until September 2008, more than a decade after ''Chex Quest 2'''s release, when former Digital Cafe employees Charles "Chukker" Jacobi and Scott Holman got together, created a new five-map campaign, and released it for free.

''Chex Quest 3'', which includes all three ''Chex Quest''s in one package, can be downloaded [[http://www.chucktropolis.com/gamers.htm from Charles Jacobi's website]]. (Requires the [=ZDoom=] source port, or a derivative thereof.)

On April 18, 2016, nearly a decade after Chex Quest 3 was released, Chukker announced [[http://www.chexquest.org/index.php?topic=5307.0 a remake of the first game in Unreal Engine 4 was in the works]].

!!This game provides examples of:

* AbortedArc: The reconstructed website contains references to an intro and ending for ''Chex Quest 2'', but they appear to be lost forever.
* AdvertisementGame: For Chex cereal.
* AllThereInTheManual: The now defunct Chex Quest website contains background information on the characters and setting.
** The initial Flemoid outbreak was the result of a lab experiment GoneHorriblyWrong. The scientist from the intro, Dr. Crispinbowl, was the only one to escape.
** The councilwoman, Admiral Wheet, founded the Nutritional Development Center[[labelnote:*]]as seen in [=E1M1=][[/labelnote]] on Bazoik [[ImprobableAge at the age of 7]].
* BackForTheFinale: The characters from the intro make a brief cameo in the ending.
* {{BFG}}: The LAZ[[labelnote:*]]Large Area Zorcher[[/labelnote]] Device. Incidentally, given that every weapon is just a reskin of a ''VideoGame/{{Doom}}'' one, it is functionally identical to the TropeNamer, the [=BFG9000=].
* BloodlessCarnage: Flemoids don't ''die'', they're just sent back to their own dimension. Likewise, when you run out of health, you don't ''die'', you merely get "slimed"[[labelnote:*]]that is, the player character is no longer able to move[[/labelnote]]. Bloodily averted when you load the ''Chex Quest'' and ''Brutal Doom'' mods together.
* CanisLatinicus: The Flemoids generally follow this naming convention.
* CompilationRerelease: ''Chex Quest 3'' comes with slightly polished versions of the first two games.
* DevelopersRoom: A hidden room in ([=E1M2=]) contains photos of the dev team and a LAZ Device.
* ExcusePlot: Goo aliens are invading this mining planet. Go zap them back to their own dimension and save the hostages. That's it.
* FantasyCounterpartCulture:
** Ralston, the Cereal homeworld, appears to be this for Earth, complete with its own. Bazoik bears some similarity to Mars.
** The IFC was founded ~200 years ago[[labelnote:*]]Chex Quest 1 and 2 appear to be set around 220X[[/labelnote]] at the resolution of the [[SpaceColdWar Cold Cereal Wars]].
* TheFederation: The Intergalactic Federation of Cereals (IFC), from whom the Chex Warrior hails.
* FictionalUnitedNations: [=E3M2=], United Cereals.
* FightingForAHomeland:
** In ''Chex Quest 2'', the Flemoids have invaded Chex Warrior's home planet.
** Ditto in ''Chex Quest 3'', but on a larger scale.
* GameplayAndStorySegregation: Flemoid larvae are depicted much smaller in the intro than they are in-game.
* GettingCrapPastTheRadar: Probably because it was included with breakfast cereal, the game documentation made a big deal of the fact that it was ''not'' a violent game, because of the BloodlessCarnage gameplay (As above, Flemoids don't ''die'', they're just sent back to their own dimension. Likewise, when you run out of health, you don't ''die'', you merely get "slimed".) This was merely a matter of documentation interpretation, and using green slime instead of red blood.
* HyperactiveMetabolism:
** Glasses of water (1%), bowls of fruit (10%)/vegetables (25%) and the supercharge breakfast (100%) all restore your health, de-sliming you instantly. Water and breakfast can also go over the 100% limit, up to 200%, just like their ''Doom'' counterparts (health bonus/soul sphere).
** According to the intro and website, Flemoid larvae can mature in seconds from as little as a single drop of milk.
* ImmuneToBullets: Conventional weapons have no effect on Flemoids, as told in the opening cinematic.[[labelnote:*]]Their slimy constitution likely allows them [[FridgeBrilliance to absorb any impact damage]].[[/labelnote]]
* ImprobableWeaponUser: The Chex Warrior carries around a ''bootspoon'' which, as the name implies, [[ExactlyWhatItSaysOnTheTin is a spoon]]. It can be upgraded to a ''Super BootSpork'', an analogue to ''VideoGame/{{Doom}}'''s chainsaw.
* JumpedAtTheCall: The Chex Warrior.
* LargeHam: The Chex Warrior.
* LocomotiveLevel: The last part of [=E3M2=] set aboard the Chex Metro.
* NostalgiaLevel: ''Chex Quest 3'' has you exploring the space station from the first game's opening cinematic, [[WhereItAllBegan including the conference room]].
* PlanetLooters: The Flemoids are implied to be this.
* SequelEscalation: ''Chex Quest 3'' has a fullscale invasion of Ralston at the hands of the Flemoids.
* ShoutOut: Several posters in the theater (''Chex Quest 2'') reference movies such as ''Film/{{Jaws}}'' and ''Franchise/IndianaJones''.
** BlandNameProduct: The arcade machines similarly reference ''VideoGame/PacMan'' and ''VideoGame/{{Asteroids}}'' in all but name.
* TeleportGun: Chex Warrior's WeaponOfChoice.
* TimeSkip: ''Chex Quest 3'' takes place 10 years after the first two games.
* TriumphantReprise: The ending features an upbeat version of the leitmotif found in the intro and [=E1M5=].
* VideoGameRemake: ''Chex Quest HD''[[labelnote:*]]working title[[/labelnote]] is set to be a faithful remake of the first game in Unreal Engine 4, albeit with expanded maps.
* WhateverHappenedToTheMouse: We last see Bazoik as it gets overrun by Flemoids, and isn't mentioned again, save for a brief mention in [=E2M1=][[labelnote:*]]A poster near the final room advertising weekly space tours is listed as canceled[[/labelnote]].
