I was playing on the official DayZ EU - DE 1297 (IP: 195.82.158.81) when at approximately 2:42 GMT I was killed by a hacker. I was chilling on a balcony of a 3 story residential building awaiting daylight (it was the middle of the night, pitch black) in Svetlojarsk overlooking the medical facility, when I was fired upon in extremely quick succession, easily more than 5 rounds per second. I estimate the distance to be at least 700m, since there was an approximate 2 second delay between the shots impacting and a loud rifle firing in the distance, with no round-cracks. They all hit the balcony material in front of me in the exact same spot. There were 2x 5 round volleys that missed but with exact precision. Then after obviously cr*pping myself, I went off of the balcony and hid inside the building, away from direct view of anything from outside, and attempted to exit the server knowing it was someone hacking. 5 seconds before I could exit my character, I was killed instantly, through a wall, wearing the 'press' ballistic vest, from as I mentioned earlier a large distance. Not incredibly suspicious on it's own, but just before the screen blacked out and the 'You are dead' message appeared, I could see the remainder of the hacker's volley hit my dead body, all within the time frame of less than a second, and hit my body in the exact same spot, as seen with the blood red splats on round impact, before the death screen went black. I am 100% certain this cheater was using hacks that showed them my position, allowed them to lock on to me despite the range, angle and darkness, fire what I suspect from the 5 round volleys to be an M70 Tundra inconceivably fast, with exact precision, with a heightened damage output and through a wall. According to wobo.tools the damage output of an M70 (which is I think the highest damaging single-round weapon in the game?) at 700m on a player with the press ballistic vest is 39.2 health damage. I was killed with 1 hit. I can confirm it also wasn't a headshot as I could see the blood splatter hitting my mid-chest.
