You do know the game is already Unrealistic enough. When Zombies can punch at buildings and rocks and break it. WHICH would be Physically impossible to do. WHICH really needs to be fixed so they can not break that stuff. But, Not the ability to dig down, which again would be Physically impossible to do. WHY, Just WHY. I mean No need to have them do this stuff at all. It needs to be fixed. Also already bad enough, that Headshots do not kill zombies instantly which should be Fixed. 1 headshot 1 kill.
