Killing Floor PC

Killing Floor is a first-person co-op survival horror, set in and around London after a mad scientist's "specimens" have broken loose and gone on the rampage. Co-op game mode for up to six players. Solo game mode for offline play. Watch those crucial and violent creature deaths in slomo "ZEDtime", even in multiplayer. 9 different monster types trying to eat your face off, armed with everything from teeth and claws, through to chainsaws, chainguns and rocket-launchers. 12+ weapons for the players to chose from, ranging from knives and fire-axes up to pump shotguns, rifles and a flamethrower. Add in a welder, medical tools and body armor to help the players survive. Persistent Perks system, allowing players to convert their in-game achievements into permanent improvements to their character�s skills and abilities. Players choose which Perks to play with, so they can best balance out a co-op team to survive the horrors. Open, non-linear play areas: choose when and where to fight -- or run. Weld doors closed to try and direct the monster horde. Full support for Steamworks features, including Steam Achievements and Friends. Fully-configurable, allowing players to change things as simple as the difficulty level or number of creature waves, or go so far as to set up their own favorite waves of monsters
