ArmA2: Operation Arrowhead is getting a lot of publicity on the simulation gaming news sites. If you've not come across this title as yet, check out the Allied Forces & Takistan Army introduction videos ( Video 1 , Video 2 )and the awesome community sites ArmaHolic.Com and ArmedAssault.Info - remember it is the community which gives life to a game, not the publishers, and ArmA2 has one of the most active and supportive gaming communities around. New members are always welcome!
With the game now available off the shelf in Australia, I'd like to suggest reading Dslyecxi from Shack Tactical's ArmA2 "Tactics, Techniques, and Procedures" guide. If you're not an ArmA series player, this background info is useful for all First Person Shooter type titles where team based gameplay is encouraged, such as the Battlefield series. This guide also covers why NaturalPoint's TrackIR is such a "must-have" peripheral for ArmA and Arma2, where he comments "the single greatest thing a player can do to increase their level of situational awareness, as well as general immersion, is via the TrackIR series of head tracking devices." You’ll find the TrackIR information on this page.
