i would recommend purchasing the game, hackers or no ive had a blast playing dayz, bought it about 2 weeks ago, the price on arma 2 is a bit steep, 29.99 for the combined operations pack which i bought on amazon, ill never touch steam with a ten foot pole as their customer service is shit, got my account taken over by a hacker and banned, good luck trying to get them to email you back. the hacking is rampant though. i would say ive been killed by hackers about 80% more than to players. usually they mass teleport everyone on the server over an ocean.
