A possible solution could be to choose (key word - CHOOSE) a PvP skin vs. a PvE skin when you come in (just like choosing Male vs. Female. If you choose PvP, you start in military camo type stuff, since that's needed to be less visible to other players (don't think it matters with zombies). If you choose PvE, you get civilian gear to start. If PvP guy kills lots of PvE'ers, gets some kind of small mark on the front of his uniform (i.e. a patch on the shirt). If guy chooses PvE and goes around killing other PvE'ers at some rate above average (i.e. if they act friendly to get close and then shoot the other guy), he also gets the patch, which would basically be like saying he's a PvP'er. It wouldn't eliminate that since prone would hide it until you in range, but might give the option to say stand up/crouch so we can check you out. For example, if an unpatched PvE'er came into a military base, they probably aren't trying to find high grade military loot to just start whacking other people. Maybe they're just trying to find a knife, or tent, or NVG's to survive at night. Benefits - PvP'ers start out with camo, which works better for hiding out from other PvP'ers - PvE'ers are identifiable, maybe PvP'ers let them go since at that point they have VOLUNTARILY identified themselves as probably not a threat. Those with the small mark might be threatening though. - Both sides get to find people easier on servers who have their same goals. - Players who go against the grain get a minor modification, only visible up close or through a scope, prone would hide it though. - Scopes or optics would help you decide if you wanted to approach the other party or not. There is no ill effect towards those who would be bandits/people hunters, outside of probably getting shot at if they approach other people (lets be realistic, they probably don't approach a lot of strangers anyways). PvE'ers, if they are checking out a town and see a whole bunch of PvP'ers in it, can avoid the town, or maybe decide to approach if the PvP'ers aren't those who have shot a bunch of PvE'ers. I don't want to make it too easy to determine whether or not to shoot on sight, but it would be nice as a person looking to stay alive if I had some way of identifying friendlies (i.e. if you are able to even see the marking, since it would be hidden if prone, wearing a ghillie suit, etc.) Comments?
