A Steam community announcement has details on an update for Borderlands on Steam to replace the game's defunct GameSpy multiplayer support with Steamworks. This page has instruction on how to update your copy of Gearbox's role-playing shooter, including details for those who have not previously installed the game under Steam. The instructions say the update will come later this summer, but that first announcement indicates this is live now. Word is: "If you have a physical DVD of the game, don’t forget you can get the Steamworks version by running the “Granting Tool” in the “Tools” section of Steam." Thanks Destructoid.
