You only DL it from STEAM or order it on a CD from them. It wasn't developed by a game company. There was a contest a while ago using the UnrealTournament Engine I believe and the winner of the Contest was given X Amount of Money to develop their game. Red Orchestra's team won the contest and have since developed the game, which wasn't released to stores because it was low key and not published by a developer. Its got a pretty decent fan-base of hardcore gamers I think, but was never designed to be a mass-market released game. They're also developing a ETO version of the game with new units etc which should be pretty awesome.
