History VideoGame / KillingFloor

* HealingShiv: The MP7 and newly-added MP5 are borderline examples. They are otherwise regular guns whose AlternateFire fires a healing dart. Unlike the bullets, the darts are not HitScan and [[AwesomeButImpractical therefore it can be difficult to hit your teammates, especially when they're strafing and jumping around avoiding the Specimens.]]

* HollywoodSilencer: Averted. The Firebug's MAC-10 has an attached suppressor, but when it was first added, anyone hearing someone else firing one heard an [=AK47=]. This has since been fixed, and its actual firing sound is still rather distinct.

* SniperPistol: The first shot is pinpoint accurate for most weapons, notably with the handguns.

* BulletTime: ZED time, which occurs randomly when a player does something impressive, e.g. getting several headshots or taking down a tough enemy. Time slows for a short time, and multiple slowdowns can be chained by the Berserker and the Commando.

** The Lieutenant Masterson player-model is [[AllThereInTheManual apparently]] one of the last specimens created, who escaped and brought the army to take out Horzine. [[NiceJobBreakingItHero Turns out this was exactly what the Patriarch had expected him to do]].

* AKA47: Zig-zagged. There are things like the [=AA12=], [=SCARMK17=], [=MP5=] and [=M4=], and at the same time there's the "{{Handcannon}}", "Bullpup", and "Combat Shotgun". Also, similar to the ''Left4Dead'' example, the game's "[=AK47=]" is actually a [[http://www.ak-47.us/Article_Detail.php?g=content1219989594 Draco AK-pistol]], modified to have a stock that doesn't get used.

** To a lesser extent, [[LawyerFriendlyCameo there's one with]] [[RedOrchestra Red Orchestra 2]] in the form of [[WarReenactors Nikolai and George,]] obtained for pre-ordering said game. Doing so also gave you a Stalhelm and a Pilotka to use in VideoGame/TeamFortress2.
* CrowningMomentOfAwesome: From killing the patriarch using the medic's mp5 to surviving a round where everyone else has died, odds are this has happened to you at least once.

* DefectorFromDecadence:

** There is also an achievement for killing four Scrakes with the [[ChainsawGood chainsaw]], their signature weapon.

* BigDamnHeroes: Sometimes, you find yourself surrounded by ZEDs and about to be killed by them... Only to find your team mates coming to the rescue.

* CrowningMomentOfAwesome: From killing the patriarch using the medic's mp5 to surviving a game where everyone else has died, odds are this has happened to you at least once.

** And with the newest update (as of now), you can use the Husk's arm cannon as a weapon yourself!

* BeatThemAtTheirOwnGame: Killing a Husk with a Huskgun. A achievement is awarded for it as well.

* ChristmasElves: The Clots became goblin-like grotesqueries of this trope for the Christmas event.

** The Scrake is meant to be the specimens' version of this. He's supposed to have been the ultimate field medic, able to take crazy amounts of punishment while saving the lives of other specimens (with amputations via chainsaw when necessary [[RuleOfCool because why the hell not]]), but he only learns by being wounded himself and has taken an unusual fascination in dishing out and receiving pain.

** The actual spirit of this trope is averted by the player characters, who move a bit slower when their health is at about 40, and even slower when that's halved.

* AlternateRealityGame: Is one of the 13 indie games that formed the bulk of the material of {{Valve}}'s "[[http://valvearg.com/wiki/Valve_ARG_Wiki PotatoFoolsDay]]" ''{{Portal 2}}'' ARG.

** ''Killing Floor''[='=]s involvement in the aforementionned AlternateRealityGame climaxed with the addition of KF-Aperture, a ''{{Portal}}''-based map with things such as pressure buttons to open certain doors. When the ARG was still running, the Trader was temporarily replaced with what appears to be [=GLaDOS=].

* FanNickname: [=GLaDOSH=] for the [[{{Portal}} Trading Sphere]] that replaced the Trader during [=PotatoFoolsDay=].

You and up to five friends take the roles of a squad of [[RagtagBunchOfMisfits a bunch of surviving military, police personnel, street thugs,]] [[TeamFortress2 the Pyro]], [[RagtagBunchOfMisfits a Queen's Guard, and more]] sent into various areas to wipe out the [[strike:zombies]] [[NotUsingTheZWord Specimens]] of a FreakLabAccident GoneHorriblyWrong. Games are divided into several rounds, in which players must kill a required number of specimens. Between rounds, the players have a minute (or ninety seconds on Beginner difficulty) to visit the Trader, a woman who sells you weapons, armor, and ammo. After all the set rounds are completed, one last round against the [[FinalBoss Patriarch]], the creator of all the specimens, who has become a genetic monstrosity himself, happens. [[ExcusePlot The game's story is not exactly a masterpiece]], but it has [[KillEmAll an obvious goal]].

* TheCameo: The RED and BLU Pyros from ''TeamFortress2'' appear as selectable character skins. See {{Crossover}}.

** For the Christmas event, anyone who owns both ''Killing Floor'' and ''TeamFortress2'' received a pair of Pyro player models for [=KF=], and Mr. Foster's gas mask and tie for the Pyro in [=TF2=].

** To a lesser extent, [[LawyerFriendlyCameo there's one with]] [[RedOrchestra Red Orchestra 2]] in the form of [[WarReenactors Nikolai and George,]] obtained for pre-ordering said game. Doing so also gave you a Stalhelm and a Pilotka to use in TeamFortress2.

A cooperative online ZombieApocalypse FirstPersonShooter for PC published by Tripwire Interactive on the [[GameEngine Unreal Engine]]. Originally a mod for ''VideoGame/UnrealTournament2004'', in 2009 an official retail version was released. While generally an updated version of the mod, there are changes- notably the "perk" system, a series of six different "classes" that players can fight as, and the fact that there was an actual professional team behind the project.

* ColorCodedForYourConvenience: The Fleshpound has a bizarre glowing...thing on his chest that TurnsRed instead of yellow when he gets mad. Player characters use to all be green and blue, too.

* FanNickname: [=GLaDOSH=] for the [[{{Portal}} Trading Sphere]] that replaced Trader during [=PotatoFoolsDay=].

* FreakOut: Mike Noble had one at a rave party after the specimens [[munched his girlfriend. He grabbed himself [[KatanasAreJustBetter a katana]] [[RoaringRampageOfRevenge and went to town.]]

* AlternateRealityGame: Is one of the 13 indie games that formed the bulk of the material of {{Valve}}'s "[[http://valvearg.com/wiki/Valve_ARG_Wiki PotatoFoolsDay]]" ''{{Portal}} 2'' ARG.

** A post-April Fool's Day update added KF-Aperture, a ''{{Portal}}''-based map with things such as pressure buttons to open certain doors and the Trader temporarily replaced with what appears to be [=GLaDOS=].

* EvilLaugh: The Scrake does this often while going chainsaw happy.

* BoomHeadshot: The Sharpshooter perk lives on this trope, but any bullet-shooting weapon can do it. Also of note: headshots on any specimen will remove its special ability.
* BoringButPractical: The 9mm Tactical you spawn with, while weak, is still useful for beheading low-level specimens, and it's one of only two weapons equipped with a flashlight. And at higher Sharpshooter perk levels, it does increasingly respectable damage, nearing the point of becoming a viable primary weapon against all but the toughest enemies.

** A recent update added KF-Aperture, a ''{{Portal}}''-based map with things such as pressure buttons to open certain doors and the Trader temporarily replaced with what appears to be [=GLaDOS=].

* EaglelandOsmosis: Inverted. Suburbia, the only map confirmed to be outside of the UK (It's in an [[{{Eagleland}} American neighborhood]]), has British license plates on some cars and some other out-of-place stuff.

** Twisted Christmas 2 adds, along with two versions of the American M4 carbine, an achievement titled "Bloody Yanks" for expending an entire magazine but only killing a single specimen with it.

* FlawedPrototype: All the specimens are failed attempts at creating [[Super Soldier supersoldiers.]]

*** The [=MP5M=] proves to be more practical. It fires more slowly, does almost twice as much damage, and holds 32 rounds (up to [[MoreDakka 64]] if sufficiently leveled as a Medic), but if you are not a medic it costs you ''5000 pounds''. For reference, the AA 12 cost 4000 pounds, a M4 with grenade launcher will put you 3500 pounds in the hole, and all the classes super weapons (Such as a ''six shot grenade launcher'',) are priced at a flat 2500 pounds.
**** Many commandos find asking a medic for a hand me down medic gun to be a good tactic, since they can carry it with [[HyperspaceArsenal two assault rifles, a hand gun, body armor, and five hand grenades]]. This will include up to 1000 rounds of ammo, and potentially twelve grenades for the grenade launcher on their second assault rifle.

*** Averted, it can DeathOfAThousandCuts very efficiently when equipped with a [[InsistentTerminology perk]] that has quick reloads. Attempting this will net you plenty of criticism.

** The Commando's version of the M4, potentially - it's basically the accuracy of the SCAR's red dot scope combined with the lower price and higher capacity of the [=AK47=].
*** Most Commandos complaints on the M4 is that it has to reload frequently, and has high full auto recoil. Both the SCAR and the H4 have the same issues. The M4's only real issue is that it does less damage per magazine, making it better against crowds of small enemy's, but worse against anything bigger then a gorefast.
