A
FPS developed by the United States Army (hence the name). I think it is probably the coolest recruiting tool that the army has ever developed. It is multi-player with single-player training missions, slow paced compared to Quake-style games, and very realistic (one shot, one kill happens often). Play this game, especially if you're an American, because you paid for it with taxes. America's Army is one of the most popular online games in existence. It comes with a mission editor and a drivable vehicle. The game is updated regularly with new features being added all of the time.
