History VideoGame / KillingFloor2

* ExcusePlot: Similarly to [[VideoGame/KillingFloor its predecessor]], the narrative is basically only found on the game's [[http://store.steampowered.com/agecheck/app/232090/ Steam Store]] page: it's almost non-existent within the game itself, due to its wave shooter roots and heavy emphasis on online play. Based on the premise, the sequel is set one month after the end of the previous game, with the outbreak of Zed clones spreading from London and the UK to continental Europe. Communications have failed, and national militaries are mostly crushed by the horde. Therefore, enter [[MegaCorp Horzine Biotech]], the amoral company whose [[EvilutionaryBiologist former CEO]] is responsible for the invasion, who hires gun-savvy civilians, mercenaries, and the few remaining European police and military personnel they can find to contain the Zed forces and thus, save the company's face by cleaning up hot-spots around the continent (beginning with their own hidden facilities dotted around Europe, of course). However, all this is just basically meant to explain the automatic [[FunWithAcronyms TRADER]] machines, the multinational line-up of core maps (which, among others, includes downtown Paris, a Scandinavian ferry port, an Italian catacomb, or a Russian prison) and the diverse cast of civilian and law enforcement characters. Later official maps (set for example in a tropical island, a nightmare world, or hell itself) however tend to heavily deviate from this premise, but no one cares. After all, the business is the same on all of them: Kill Zeds, get money, buy weapons, kill the Boss, rinse and repeat! No need for spoiler tags or any meaningful story here.

After the successful ''VideoGame/UnrealTournament2004'' mod ''Videogame/KillingFloor'' gained traction and became a full release in 2009, Creator/TripwireInteractive took a couple of things learned from their other games released in the meantime, and created ''Killing Floor 2''. The game got released as an Early Access title in April 2015, to fix bugs and receive plentiful feedback to improve on the Killing Floor formula, along with letting players experience a bit of the game before it fully launched in November 2016 on both PC and UsefulNotes/PlayStation4, with an UsefulNotes/XboxOne port following the next August.

** The Pulverizer is a [[DropTheHammer sledgehammer]] with a magazine of explosives feeding into it. Using heavy attack will detonate one on impact, adding a shaped explosion to the actual swing. If the magazine is empty, only the actual hit will do damage. The light attack, jab, and block don't use ammunition.

A third game, simply named ''Killing Floor 3'', was announced during 2023's Gamescom.

In the beginning, London was reduced to ruins as someone at Horzine Labs let out [[GoneHorriblyWrong some specimens who weren't supposed to end up like they ended up]]. So, what do you get when a containment breach occurs and the specimens run havoc in not just London, but the rest of Europe? As more people attempt to fight back specimens, someone is causing them to spread, even after the Patriarch's final death.

* AcceptableBreaksFromReality: The RPG-7 has an ArbitraryWeaponRange like the M79 and won't detonate if it hits something less than about 10 meters away, which is incorrect because its original-issue ammunition uses a simple contact detonator that does not have a minimum-range safety feature.

* AllThereInTheManual: Know the plot for the last game?[[labelnote:You don't?]]Kevin Clamely was set up to make super soldiers, his son was killed and he was much less ethical about his project as he considered the Specimens his children. As more of the workers at Horzine Labs started seeing things not being completely okay, Kevin did the only thing he could do before it was shut down: Use himself as a test subject. Cue the Killing Floor 1 Objective mode update that expanded a bit on the story, concluding that Kevin's own daughter wanted to put an end to the Zeds and that Kevin cloned himself. Oh and the team takes a train to Paris. Cue sequel.[[/labelnote]] Okay, well, you're sent in to kill lots of freak cloning specimens, get money, buy better guns, survive to kill the boss, rinse and repeat until the game goes gold and possibly gets a plot-point like the last game. [[note]]Nope![[/note]]

* QuickMelee: Every gun can be [[PistolWhipping used as a bludgeon]] against enemies. These attacks do very little damage (just barely enough to decapitate the weakest Zeds), but can cause almost any enemy to stumble, interrupting special attacks such as grabs--just don't think you can stunlock enemies this way, because they'll be ImmuneToFlinching for a few seconds afterward. For actual melee weapons, the button for stock bashes is how one of their attacks are used, generally a quick thrust.

* SatchelCharge: Available to Demolitionists in the form of an [[https://killingfloor.fandom.com/wiki/C4_Explosives explosive C4 charge]] that can attach to various surfaces and packs one hell of a punch when set off. The only downside is that they're a little on the expensive side and are (naturally) a single use item in a game where enemies typically attack in groups of six or more.

** When looking at different kinds of viscera, Masterson will sometimes say "Creator/HPLovecraft would get off on this stuff..."

** Some of Tom Banner's face paints are a reference to more famous war paints [[Film/{{Braveheart}} "Freedom!"]], [[VideoGame/GodOfWar "To War!"]], and [[Film/MadMaxFuryRoad "Valhalla!"]]

* SinisterSubway: France has some pretty nasty subways which can be seen on the maps Burning Paris and Hostile Ground. The lack of light and hordes of Zeds [[SarcasmMode make them a fun place to traverse.]]
