really needs improvment. Smarter guns. Dont attack the guys that are just coming out or way far away from the exit. Make them attack the ones closest to the exit instead.
bad controls, bad game, to hard to see whats what, you get stuck on corners, ammo bar doesnt exactly represent what ammo you have left. Too much wrong with it... my suggestion dont try to figure out ANY of the game just run around find your 30 zombies and flag it with a 1 and move on.
