Just bought Killing floor for mac. Ill let you guys know if it is any good. in a future update.
**update**
ok, so if i can sum up Killing Floor in a few sentences it would be this. Killing Floor has got to be one of the best games i have played in a while. For 13$ this game is a complete steal. I recommend everyone to got out and try this game. I have given my guest pass to AG and i hope he will give his review soon. He liked it too but maybe not as much as me. (he doesn't like killing zombies like i do :P )
