You can download it from here, at the princely size of 1.3gb. Word on the street (well, in the pub at least) is that this is a pretty good iteration of the soldier series, at least offering some competition for the mighty Call of Duty games. Airborne contains lots of hot parachuting action, violence against Nazis, and broad levels to allow you some shooting freedom in an otherwise linear action game. Huff huff, or whatever it is American soldiers say.
Jumping out of a plane: Manly.
