Bohemia Interactive has released an update for Arma 2: Operation Arrowhead that’s been 2 years in the making. Update 1.63 includes a tremendous amount of bug fixes as well as a transition from Gamespy’s matchmaking over to Steam.
As you may have heard, GameSpy is discontinuing its services and it was therefore of paramount importance to offer an alternative for the passionate Operation Arrowhead players who have supported our game and our company for so many years.
Due to the fact that Steam based matchmaking requires Steam to work, this update is only available through Steam. If you have purchased a retail copy of the game, please do not despair. As announced previously all Arma 2 (including DLCs and Operation Arrowhead expansion) keys may now be activated on Steam. Just follow this walkthrough (link), take your Arma 2 CD key, use it as a Steam product key, and the game will be added to your library.
Score another one for Valve and the PC Master Race as another developer ports their game off of a dying service over to Steamworks. With the shutdown of Gamespy and the storied history of Games for Windows Live, this year has been a great one for Steamworks.
