I was logged in with 2 other friends and we suddenly got sniped while being inside our base, which is behind a hill with forrest, with instant headshots to each of us within 10 seconds.
After that I tried to get back to the base and as I got close, I got killed again, out of nowhere. Once again I tried to go back and suddenly the base was attacked.

What was interesting is, that about 1h before that we found a fully geared but dead player in the middle of nowhere with ruined headgear. That person has not been looted which made no sense since he had 2 VSDs and more on him. But he was just there and nobody cared about him --> I assume headshot through aim bot of a hacker.

This is not the first time that we encountered hackers on that server.
