Activision's announced that the PC version of Call of Duty: Black Ops will include full Steamworks support.

The FPS - which is now available for pre-purchase on Steam - will leverage Steamworks' Auto-Updating, Achievements, and more, says Activision, as well as support for Steamworks Cloud technology.

"We are delighted to be delivering the year's most anticipated title with Black Ops to PC gamers around the world," said Jason Holtman, director of business development at Valve.

"We've collaborated with the development team to leverage the Steamworks suite of services to deliver the highest level of service to Call of Duty: Black Ops PC customers."

Mark Lamia, president of Treyarch added: "Steam has been a great partner throughout development of Black Ops. We're working closely together to take full advantage of Steamworks to ensure we deliver the most polished and secure PC experience that our community deserves."

Black Ops is out on November 9.
