(Forgive me for bad typing) I found a partner, we were waiting for his friend when we hear gunshots. I saw the guy and told my partner to cover me, I use direct chat and tell him friendly, even typed it. I felt something was wrong, then he starts running in circles I keep telling friendly, friendly then he shoots so I shot back and so did my partner. First time killing someone, he dies but I was really low health. We waited and my partner friend came then we heard gunshots again so we check it out, some guy shooting at some zeds. We tell friendly or to put his weapon down, he doesn't listen comes back and starts to raise his gun, we shot him and he dies. My two partners disconnect and I soon went by myself to the airfield where I died from been low in blood.
