A Steam Community post by the R.U.S.E. Team has the unexpected news that R.U.S.E. will not use Ubisoft's DRM scheme, much reviled by gamers for requiring a constant internet connection (thanks joao). The upcoming real-time strategy game will instead use Steamworks, and will support single-player play even without a 'net connection. This message is repeated on the Ubisoft Forums, where they add that more news is coming soon for console players:

This news is destined to our PC players audience, so please spread the information if you know some.

When R.U.S.E. is released in September, it will benefit from Valve’s Steamworks API to offer the best community experience to players. Consequently, a Steam account and Internet connection will be required to activate the game, as per Steam policy. For this reason, R.U.S.E. will not use the Ubisoft protection. Single player can be played offline. Console players, stay tuned for more R.U.S.E. news in the coming days !
