Today, 20 minutes ago, a cheater just killed me.
I was playing on official vanilla server : DayZ EU - DE 1297 (1st Person Only)
My steam page : https://steamcommunity.com/id/MrAliG/

At some point, I was in a field and random flash grenades started hitting me and I heard some shot coming from what seemed to be North.

After taking cover, I still got hit by a shot, that was suspicious but I thought there might be someone else. Then I entered a buidling, in a room with no windows and again, grenades started poping out of nowhere. Usually I don't do that, but I was 100% sure that was a cheater so I dicided to disconnect even tho I was in a middle of a "fight". I was locked down in a room without any windows and of course during the 15secs, he somehow killed me with a shot even tho, no one was in the room.
