I’ve been playing a lot of Killing Floor recently, and I like it quite a lot. It’s not perfect though, and while undoubtedly loads of fun it makes a few stupid mistakes that I think make it deserve its 70% metacritic rating. The best way I can describe Killing Floor to someone who hasn’t played it would be ‘the B movie underbelly of Left 4 Dead’. It’s an FPS with zombies meant to be played co-op. Where L4D limits you to 4 people though Killing Floor allows 6 (actually limitless with a bit of jiggery pokery), and that’s the end…
