The PC version of Gas Powered Games' Supreme Commander 2 will run on Valve's Steamworks and come with online achievements, auto-updates and, yes, Steam's DRM.
Both the retail and electronic versions of Supreme Commander 2 for the PC will be powered by the service. Valve also announced that the demo for the game is available now and people chomping at the bit to spend money on the March 1 game can pre-purchase the title through Steam.
No word if the integration of Steamworks into Supreme Commander 2 will impact whether the game will be sold on Direct2Drive, Impulse or GamersGate. All three of the digital distribution services refused to sell Call of Duty: Modern Warfare 2 after Steamworks integration was announced for that title.
