I was killed last night by the small airfield. When I respawned I found about 5 other random players who were in the same area as myself. People are basically friendly if no one has any good equipment. One had a revolver and another guy had a shotgun but other than those two, the rest of us had nothing or just a hatchet--everyone was friendly. From now on, once I get a gun, I am treating everybody else as hostile unless I am playing with one of my friends....I have not encountered anyone else in the game who is not hostile who has decent equipment.
