Its a good game but however the objective is kill all zombies but why are their people shooting at you and also too many zombies spawn at once. maybe add waves of zombies. the starting ammo was too much. I didn't have to refill my ammo much to kill everyone. too many ammo crates. Really good idea that the game detects low FPS and fixes it because it really helped. also the game doesn't end when you kill everything. your just running about doing nothing.
