from the russian game pics, that Bigrik posted up awhile back, the zombies wore alotta clothing, and had like a....pie pan thing taped to there abdomen, im guessin that was the only place u could shoot the zombie for a hit to count. if thats not the case o well i still like that idea lol
headshots will lead to bad things.
physical contact will lead to worse things. i know if i was hot and sweaty and tryin to kill somone, if one was to accidentally push me a lil too hard or trip en route to kill me, and wind up tacklin me...well u get the idea.
tempers flare bad enough just shootin at each other
but if everyone is cool by the idea and everyone agrees that the 2 hand touch thing is ok, they have no reason to complain
EDIT: heres bigriks post:
