I just had some thought that I think would make zombie mod much more fun.
"Zombie points" for the amount of zombie's one kills. With the zombie points one can buy various different upgrades such as "holy hand grenades" The top 1 and 2 ranks would get a different human model, such as a priest and get limited immunity. "immunity" would be something like resistance to a zombie knife. Say if the priest had immunity 2, he could withstand two zombie knifes.Or course this could be optional to the server owner and could disable it by changing a certain cvar.
