Valve has confirmed that Activision's Call of Duty: Modern Warfare 3 will be using Steam. All PC versions of MW3, downloadable or retail, will include Steamworks integration.
Dedicated servers were already confirmed a few weeks ago for the PC, so this announcement didn't really surprise anyone. The Steamworks integration is still good news, as it allows PC gamers to enjoy auto-updates, achievements, friends lists, chat and more.
