On Thursday we (group of 6) were playing on the EU-01 Experimental Server when we encountered a hacker south of Berenzino. He was friendly to us (don't know why, maybe because we didn't kos'd) and talked a bit with us. At first we didn't know it was a hacker, but after we asked him for matches, he said "i'll get you some" and flew over to Berenzino. We heard shots and after 2 minutes or so, he came back, bleeding like shit, dropped all of his gear (matches were inside his black jeans) and asked on of us, if he could kill him. He said, he needs a new spawn and will come back to us later. He also said, there were at least 3 bandits in Berenzino and we should not go inside if we want to stay alive. After we shot him, we headed west into the woods, made a fire and began with our bbc :)
5-10 minutes later he came back (seems like he teleported to one of us) and hung out with us. We asked him how i does flying and shit and he only responded "magic". He brought some other stuff with him, like a akm with no attachments, another blaze, a hunting backpack full of m4 attachments, 2 pistols, pistol magazines and a shitload of other stuff. everything was pristine.
he also floated in the air and above our campfire, the a took a swim over us an the fire and sooner or later he flew away.
you can see some of this in the following video: https://www.youtube.com/watch?v=b1A5xVjpahE
we checked his pulse and his ingame name was "karma". the time we encountered him was between 10-12pm on the 5th of june (german timezone).
