Killing Zombies is recuiting, if you're looking for an invite pm the admin.

We're a group of mature players that enjoy playing co-op games and are looking for like minded players to join us. The games we play are mostly focused on Killing Floor, Left 4 Dead and Zombie Panic! Source. We're looking for mature players that try to focus on co-op gameplay and team work so working together is key for us. We don't take kindly to those who wonder off from the group just to rake in the kills and risk the rest of the group. So we ask that you join us only if you understand and are able to play by our rules. Besides, our main focus is to have fun!
