Got haxed on Dayz!

[{420}Mr.Smiley 53]

Alright so as me and a group of 4 other guys made our way into elektro we see a random guy walkin into town too, than all of a sudden he gets dropped we hear some kind of very powerfull sniper rifle (AS50) it sounded EXTREMELY close but we couldnt see anyone so we just said fuck it and made a break for it to elektro, we continued to get shot at at this very very close range but couldnt see anyone, after we made our way into elektro we hear some kind of assult rifle rounds popping off and zombies all around us started dropping, and than we see a huge trail of blood coming out from thin air on an invisible player, we freak out go to the firestation and than as we turn back around a dirt bike majically appeared.... we're like WTF one of us gets on the bike... and than 5 more appear.... and than we see the hacker, Alboz, we see him appear suddenly. Afterwards we just dicked around with him, he teleported us all over the place, he was spawning in all kinds of crazy cars, jets, helicopters, and he gave us(not by choice, it was forcably placed on us) ghillie suits, coyote bag filled with ammo and supplies with as50s and m4s. Anyways after we started to disconnected it kept telling us we were missing some kind of file when we tried to join a game, or even the base game. Today however, steam prompted me to update arma 2 and has seemed to fix it.

Ill post a video of this tommoro, please take care of these haxors
