Spent a good amount of time in the Official Dayz Us - LA 5654 server 85.190.157.113 and on separate instances me and my friends have been killed by hackers we would be sitting in a small shed to hide and one shot from really far away would kill us all in one shot in one instant and then another instance we were in our base that was completely closed off and we all died in seconds even though we were in perfect cover and the hackers then stole the base. All cases there was no sign of the hackers only gunshots that sounded miles away.
