All PC editions of Borderlands 2 will use Valve's Steamworks suite as their DRM, publisher 2K Games announced today. As Steamworks supports snazzy features beyond simple copy protection, Gearbox's shooter-RPG will also use it for multiplayer matchmaking, Steam Cloud storage, achievements, auto-updating, downloadable content, "and more."
How Steamworks... works is that if you buy a boxed edition of Borderlands 2, you'll need to register the game with a Steam account, and launch it through Steam. The box will still contain a disc to install the game from, but you'll have the option to download it directly through Steam whenever you please. Digital distributors other than Steam will simply sell you a product key to activate on Steam.
Steamworks was to be expected, really, as 2K Games has used it for PC editions of games it's published since Mafia II in 2010. It briefly dabbled in Games for Windows Live before then but, thankfully, that was a short-lived experiment.
Borderlands 2 is coming to PC, Xbox 360 and PlayStation 3 on September 18. As ever, a selection of shiny things are on offer as pre-order bonuses.
