Killing Floor

Killing Floor is a cooperative survival horror first-person shooter set in the cities and countryside of England after military cloning experiments go wrong. You and your friends are members of the military sent into these areas to survive long enough to clear them of the failed experiments. Up to six players face waves of specimens, or you can play solo offline.

Fight the specimens

Ten types of monsters attack with teeth and claws, chainsaws, chain-guns and rocket-launchers. You can choose when and where to fight or run in open, non-linear areas, and weld doors shut to steer the horde through other corridors. Equip your team with welders, medical tools and body armor, and choose Perks to balance the team against the creatures.

The game includes more than 33 weapons, from knives and fire-axes to pump shotguns, rifles and a flamethrower. Its configurable settings let you change the difficulty and the number of creature waves, or set up your own waves of monsters.

Perks and ZEDtime

The persistent Perks system turns in-game achievements into permanent improvements to your character's skills and abilities. Slow-motion ZEDtime lets you watch crucial creature deaths, including in multiplayer.

Achievements and creation tools

Killing Floor has over 170 Steam Achievements. Examples include “Dignity for the dead,” for killing 10 enemies while they feed on dead teammates' corpses, and “Hot Cross Fun,” for finishing off 25 burning enemies with a Crossbow. The game also includes a Windows-only SDK for creating new levels and mods.
