Tag! You're IT. But this time, you really are an IT. By "It", I mean a zombie who is after Braains!! This is a zombie vs human tag war. If you are a zombie, the objective is to spread infections. If you're on the human side, you prevent infections from spreading.

Simply move your character with WASD. Oh yeah, try not to doom your teammates and leave them open!
