no ArmA is not free but it is WELL worth the 20 or 30 bucks, you know on warrock when you get shot down in a helicopter it just blows up, in this one if you shoot the tail rotar or the main rotar it jams and falls to the ground its very realistic. you can fast rope down building sides, off helicopters.
and you have to try being a sniper, you REALLY need to get a bunch of friends together becasue you need to be organized.
and to show yout he graphics hers the ingame movie
