The first two guys I saw when I started playing, we just ignored each other. That was when bandits still had skins, so there was no real PVP between survivors (as far as I know). After that I died 3-4 times to bandits shooting me in the back, either in Elektro or in Cherno. Right after that, I decided to try killing someone else myself. It was a decision I made when I saw a freshly spawned guy AFK on the beach. I know, it's cheap, but I wanted to know the consequences, and a spawn kill yields less impacts. I asked "FRIENDLY?" in the chat a couple of times, then took the shot with my Makarov... Apparently another survivor heard the shot, cause he came to inspect the body. I killed him too ;). I immediately turned bandit and stayed that way until the bandit skin removal. I haven't killed any survivor since then, unless I felt threatened. I don't even ask if they are friendly or not, I just avoid them. Last time, with 2 other guys I roll with, we saw a group of 3 players that had not seen us. We could have taken them out easily. Plus it was at NW AF. As we wanted to loot the place too, we had to do something. Instead of murdering them with a grenade, we simply asked if they were friendly. They answered positively, let us check the fire station to share the loot, and then we left. I felt good about myself... I was also 300 m away with my DMR, making sure they held their part of the bargain ;).
