I was playing Dayz on PC on an official server when I was killed by a cheater. I had been sitting at the top of a staircase in a house for nearly 30 min watching a tv show on my other monitor without moving. 2 began throwing grenades near the building I was in. Rather than log off when I suspected wall hacks, I silently waited and didn't move. They came closer to the house, circling it a few times. Then they entered the house and edged up near the corner at the bottom of the stairwell. They then threw a cooked grenade around the corner at me, killing me. They did not have vision of me and did not do this to any other houses in the area. They beelined for the house to kill me.
I know it may sound like I was being salty, but I gave no sound or vision cues that I was in the building, and I did not have zombie aggro. They should have had no way of knowing that I was there. I've listed the details of the incident below.
