to limit random killing of other players, why not set a counter for human kills - making you a bandit if you kill too many "humans" - rach bandit rank carries a penaltu ex. appearing on map for a short time or if really notorious becoming a bandit till you die. on another note "legit human kills" would be a problem - maybe something like 20 zombie kills erases human kills or bandaging players reduces human kills. exploitable but atleast it makes it harder to just randomly kill people.
