'''Quake IV''' is the fourth entry in the {{Quake}} series, launched in 2005.
The game was developed by Raven Software, using the Id Tech 4 engine (''Doom 3'' engine) and it's set in the Strogg arc, as a sequel of ''VideoGame/QuakeII''.

After the events of ''VideoGame/QuakeII'', the EDF starts the invasion to the Strogg planet in order to terminate the Strogg menace once and for all. The player controls Matthew Kane, a corporal of the Rhino Squad, and he must assist his comrades in the given objectives.

The game has a [[Characters/QuakeIV character sheet]], currently under development.

----
!!This game provide examples of[[labelnote:*]]Bear in mind that a lot of tropes from ''VideoGame/QuakeII'' also apply here. Also, the Character tropes go to the Characters page.[[/labelnote]]:

* AirVentPassageway: There's an escape using one in the level after [[spoiler:Kane's Stroggification]], just before Kane's first encounter with [[spoiler:a Teleport Dropper]].
* AlwaysChaoticEvil: The Strogg race.
* [[spoiler:AndTheAdventureContinues]]
* AndIMustScream: A conversation overheard hints that the victims that are Stroggified are, for a time, aware of their actions but can not stop them. [[spoiler:This is later shown to be true when [[TragicMonster Voss becomes Stroggified]].]]
* AnimalMotifs: The squad names: Badger, Bison, Cobra, Eagle, Kodiak, Scorpion, Viper, Warthog, Wolf, and, of course, the Rhino Squad. There's also the [[AuthorAvatar Raven]] squad, composed by members with the same names as the developers of the game.
* BackFromTheBrink
* BadassDriver: Whoever is driving the truck in the early Nexus mission in ''Quake 4'' has got to be crazy.
* BeamOWar: The Railgun.
* BeamSpam: The Lightning Gun.
* {{BFG}}: The Dark Matter Gun.
* BigDamnHeroes: When [[spoiler:the Rhino Squad]] saves [[spoiler:Kane]] from the final part of the Stroggification process.
* BioPunk
* BlueOrangeContrast: A variant. The Marines are, rather than blue, olive green, while the Strogg are orange. This is reflected in their respective UIs as well as in their uniforms. It also makes Matthew Kane stand out even more, post-Stroggification, when standing amongst the rest of Rhino Squad.
* BodyHorror: [[http://www.youtube.com/watch?v=3clVvh5gbGE The Stroggification process]], where the subjects are put into heavy sedation and, as a result, are [[AndIMustScream 75% paralyzed]]. Through an assembly-line-like process, they ''rip open your stomach, saw off your legs, fuse new legs and armor to your skin, put a big helmet on you, insert a control chip into the victims brain, and then activate said chip so he/she can serve the Strogg.'' Fortunately, [[spoiler:Kane]] is saved from that last part by [[spoiler:the Rhino Squad]]. Too bad the same can't be said for the many other poor souls before you that already completed the process, which you can see in the [[PeopleJars body jars]] moving around the facility.
* BoringButPractical: The Machinegun in single-player, especially because it's one of two weapons with a flashlight, the other being the Blaster.
* BossInMookClothing: Many examples in the fourth, specially Gladiators. Heavy Hovertanks are this plus outright DemonicSpiders, while Light Tanks are fairly LevelFiveOnix provided you've got enough room to keep backing away from them. They're a pain in the ass, anyway.
* BossRush: Just before the final battle, [[spoiler:Kane]] is locked in a small-medium sized room and forced to fight 3 consecutive groups of the BossInMookClothing enemies: 3 Light Tanks, 3 Heavy Hovertanks, and 3 Stream Protectors.
* {{Bowdlerization}}: The German version removes the blood and gore and censor some scenes (such as [[spoiler:Anderson's death]]) However, the dub wasn't changed to accommodate the censorship and so quite a few lines turn into [[DubInducedPlotHole non-sequiturs]].
* ChainsawGood: The Gauntlet, available only in multiplayer mode.
* CypherLanguage: The Strogg languange.
* DegradedBoss: The Harvester first appear as a {{miniboss}}-type encounter, then as a regular GiantMook later.
* DramaticSpaceDrifting: In the intro. Seems that is's just a marine contemplating the emptiness, then he turns to reveal a disfigured face and then half a body missing.
* EmbeddedPrecursor: In some editions, the original ''VideoGame/QuakeII'' was brought with the game.
* EnemySummoner: The Teleport Dropper, that Strogg which looked like a bulldog, and could disperse several teleporters which summoned several Mooks. These can also appear at the Strogg teleporters on the game. [[spoiler:Strogg!Voss]] also has this ability.
* EvilSoundsDeep: The Strogg voices heard throughout the game, including the Makron's voice.
* ExplodingBarrels
* FateWorseThanDeath: Stroggification. As if being conscious through all that mutilation isn't bad enough, until your higher brain functions atrophy, you're forced to watch as your body is used to kill your fellow men.
* FlunkyBoss: The majority of the bosses fit this trope, if you don't count the first Makron encounter as a boss.
* GiantMook: Stream Protectors, Light Tanks, Heavy Hovertanks, and Gladiators.
* GiantSpider: The Harvesters are ''enormous'' and rather spider-like in appearance.
* HalfTheManHeUsedToBe: This happens to an unfortunate Marine who attempts to enter a Strogg teleporter.
* HarderThanHard: General difficulty. The weakest, basic enemy Mooks can kill you in just a handful of shots. All enemies have noticeably more health, so that even mid-level enemies like Berserkers and Gunners take more than a full clip of assault rifle fire to kill. Your teammates are no longer invincible powerhouses, making all levels with them into {{Escort Mission}}s. The game is already fairly stingy with Health and Armor on ''Normal'', so imagine what all this is like on HarderThanHard. [[{{Halo}} Legendary]] has ''nothing'' on this.
* HeadsIWinTailsYouLose: Kane's first encounter with [[spoiler:the Makron]].
** HopelessBossFight: Although it's somewhat unique in that [[spoiler:Kane ''does'' have to damage him significantly]], otherwise he just straight out kills him (game over man, game over) instead of immobilizing him with his tractor beam.
* HumanResources
* IndustrializedEvil: Stroggification.
* KeystoneArmy: The Stroggos. Once [[spoiler:the Nexus]] is destroyed, every Strogg force perishes.
* LightningGun
* MajorInjuryUnderreaction: When on the first to the Hannibal, you can hear this exchange when exiting for the field:
--> '''Marine''': Hannibal! I need a medic!\\
'''Medic''': Who are you? I not able to get a reading on your medchip.\\
'''Marine''': Corporal Thomas Alvarez. My medchip is damaged.\\
'''Medic''': But your medchip's implanted in your heart!\\
'''Marine''': I know... I'm looking at it right now.
* MoreDakka: Some vehicles.
* NailEm: The Nailgun. In the campaign mode, you can upgrade the weapon, so it can shot homing nails, by keeping the alternate fire button pressed.
* NitroExpress: One EscortMission has a demolitions expert carrying explosives that will "take out half the mountain" if set off.
* NoOSHACompliance: Any Strogg facility you could think.
* {{Nostalgia Level}}s: ''Quake IV'', Multiplayer-wise, plays this straight with its remakes of "Claustrophobopolis", from the first ''Quake''; "The Edge" (plus a CTF version) from ''Quake II''; and "The Longest Yard" and "The Very End Of You" (renamed as "Xaero's Gravity") from ''Quake III Arena''. Subsequent patches added also "The Camping Grounds" from the latter.
* NotUsingTheZWord: Played straight with the actual monster names, averted in-game where one of the marines panics after getting bit by a "zombie" before being corrected that they're just botched Strogg.
* PointOfNoReturn
* SecondHourSuperpower
* SmashingHallwayTrapsOfDoom
* SpaceMarine
* SpiderTank: They're called the Harvesters and Kane find them four times: the first two before the Nexus tower as a human, the second when [[spoiler:Bidwell dies]] and the last once you've escaped from the Strogg Medical Facility [[spoiler:as a Strogg]].
* StrappedToAnOperatingTable: The entire stroggification process, although the victims aren't strapped to the tables--they're just heavily sedated.
* SuspiciousVideogameGenerosity: Used right before [[spoiler:the first Makron battle]]. [[spoiler:Kane]] runs down a hallway lined with ammo to an obvious ambush. After taking out the two (relatively) easy Stream Protectors, [[spoiler:the Makron]] shows up. In spite of it being a HeadsIWinTailsYouLose scenario, if he doesn't do enough damage to it first, he will die; he has to "win" to advance.
* TranslatorMicrobes: When [[spoiler:Kane]] is Stroggified, the chip implanted in his brain lets him read and hear the Strogg language as English.
* UnwillingRoboticisation
* YouDontLookLikeYou: The entire Strogg race.
* ZombieApocalypse: The level before the second squad intermission is all about this. [[NotUsingTheZWord They are called "Failed transfers" and "Slimy transfers"]].
