This is not true! Dude you can crouch up to zombies. Haven't you ever tried? if u got agro, go into a bush so he starts walking away and then crouch after him and he wont see you! u can even hit him in the back easily with an axe! And for the "overpoweredness" of zombies.... this is not true, u can always outrun zombies (although they do run faster than you, they stop every 2 sec so that ur actually faster then them) ad WTF!! who needs a house to lose zombies?? Dafuq!?
