Summary :
Killing Floor is a 2009 Co-op survival horror based game, a bit same as "Left 4 Dead" but I can say this is more gory, challenging and thrilling.
You can play single player mode or Lan with friends and there are 5 maps for you to choose. Each map can have maximum 6 players only and the mobs come at you wave by wave.
There are total 7 waves, depending the difficulties you choose.
Each waves the mobs get stronger and the final waves you need to kill the boss "Patriarch".
For every wave you finish killing, you will provided with some amount of time to get to the "Trader" to stock up your ammo and buy new weapons. Sometimes you can find some ammo or weapons randomly on the map.
Another difference between Left 4 Dead and Killing Floor is Killing Floor have few seconds of slow motion aka "ZEDtime" for you to aim better and enjoy seeing the mobs organs being split, bomb, fly, burst.... apart b(￣▽￣)d "REST IN PIECES" Zombies! yeah!


The part that I not really like is the speech they talk in game. The way they talk like "too relax". ┐(─__─)┌
