You can download Killing Floor for free on Steam this weekend!
Tripwire Interactive’s six player cooperative survival horror first-person shooter has players mowing down wave after wave of enemies with their friends in a non-linear, open-ended world of various, fully customizable, levels. Each wave of mutants may be crowd-controlled by bolting shut doors and creating choke points, but players will have to keep on the move to rearm themselves via a relocating trader. The game is based on a mod for Unreal Tournament 2004.
The Steam deal also includes an all-new ‘Level Up’ Content Pack that contains 3 Maps, 7 Weapons, 20+ Steam Achievements!
Free FPS zombie play? Sounds good to me!
