This is quite an easy solution if you guys are looking for one, i learnt it the hard way when it was 2nd day into the game. Crouched in a bush i was configuring my settings, as i was a total noob in the game and dont even know half the controls, i had a hachet and a hunting knife , it was already a godly step for me. I would think it was a friendly who approached me and voiced me to lie on the floor, i didnt respond as i was checking my settings , he then proceeded to blow a hole in my foot and ran away, i had no medical gear, was bleeding with broken bones crawling in the middle of nowhere deep in the forest with my vision blurred it was such a shock as i was so helpless that i had to suicide and respawn, but not before raging using voice and local chat at the guy who shot me . Well in the end, i didnt really blame him, and i do approve his tactic, as suggested quite a few times already in this post, best way to avoid a kos way for survival is to talk to the person when he can't see you, if he ignores you , avoid , if he loads up his gun and starts looking for you without replying, you annihilate him, currently i have an m107 looted inside the baracks from an afk guy's back pack (ho ho ho) and i am surely itching to use it on a bandit. Bandits really do make the game, to have good , there must be bad, if there wern't any bad guys in this game, i wouldnt even bother playing, paranoia is what keeps me and my buddys playing this game, its ok if people want to be assholes, that gives us more organised survivors something to shoot at. :D
