Infact it is quite realistic - Of course, you can't kill zombie by simply punching his head, but it would be nice to punch him, in order to stop his movements for a few seconds. If this isn't possible with the Arma engine - Ok, I won't bother anymore.
Morgan, yeah you are right with your last sentence. But still, some kind of weapon, even if it's your fist or foot, would be good. Maybe it's just me, but I would appreciate it.
I don't understand why you don't want one honestly.. I really don't. I mean, spawning with a rifle or a pistol is kinda boring, I admit that. But at least a melee weapon, to defend yourself in the beginning.
