Maybe add Military NPCs. You could join them, they could have a base, movement of troops around the map or maybe you want to rob them Joining the Military: Maybe you could join the military and earn your way up the ranks so eventually you could command a squad or the entire military on map (may interfer with the whole same player on a different server) but it shouldn't be hard to solve. This may also start corruption etc. HQ for Military: Maybe they could have a base where you start (even though I enjoy the random spawn points) this is considered a safe point but maybe not all the time. They could also get overrun by zombies on random events. Movement: They could move around the map and bandits or players could rob them or the players could stick by them. Also they might rock up at hearing gunshots and loud sounds. JUST A SUGGESTION xD
