A friend and me were running near the military tents South of Dubrovka on DayZ AP - SY 0978 (1st Person Only). We both simultanouesly were instant headshotted with no previous shots, sounds or warnings. I have experienced this style of death in windowless rooms where my friends and I all simultaneously died by instant headshot. The style and nature of death makes it clear it was cheating.

This seems to be a persistent problem across the many official servers and is extremely frustrating. I have been playing DayZ since it's early access and the cheater's have been a problem since day one with nothing being done. Battleye is not operating as intended as these cheaters keep getting in.
