First of all, I dont have any evidence as I dont record my screen. I was running to the airfield through the forest as I heard two or three shots hitting near me. Zombies started going after me and I was hit by zombies before. Screen was black/white. Hided in the barracks, patched myself up a bit. He came in, didnt see me at first. Shouted at him to leave. Didnt react. Wrote in chat. He stood approximately 5m away and told me that im a tresspasser and that he wants to search me. Now he either walked forward and his weapon lifted that way or he lifted his weapon. I shot.
Why I left 18 minutes after is easy to explain: My League of Legends Squad came online and asked me if i want to play with them. Thats the reason I left.
I want to add that im concerned about that I did something wrong and that I´m really sorry about that.
