Hey guys is that legit to shot someone in the head and after like 2 or 3 mins later wake up and go away. I know this is a zombie game but really what the hell? Actually i was looked for some spawn snipers who camped on electro hills, and i found the first one boom headshot go for loot go back to wait someone else. Like 1 minute after comes the neyt one to loot the body boom headshot defenetly dead both of them. I camped more and in the 3rd or 4th minute both of them woke up and run away like headless chickens. Also I know ist alpha and everything and shit happenes sometimes but seriously wtf? And I also know I shouldnt post it here but this threed watches the most. If you have any idea what happened pls tell me your thoughts. Thanks Nemet
