Killing Floor

Probably my favorite co-op video game ever. Some of the best feeling guns ever. There is an impressive balance here, and even the most basic zeds are lethal. After playing 2, I'm pretty sure this game's success is in some part an accident. Everything here is too perfectly tuned. Sure this game feels and looks older, but it's just a better experience to play. Sometimes less is more. I still hate the excessive perk level grind, but I won't let that ruin the hundreds of hours of fun I had.
