Crisis:
Crisis is an infection gametype on a modified map of The Pit. The humans start off in the sword room which is basically a massive armory, and can either stay there or go to the high fortress on the other side of the map (the upper room) where there are BR's, AR's, Shotguns, a Sniper Rifle and a lot of grenades. Try to survive the upcoming onslaught.
