Call of Duty: Modern Warfare 3 will use Steamworks
Call of Duty: Modern Warfare 3 will use Steamworks, CVG report. That means even retail copies will need a Steam account to run. Steamworks brings with it all the usual benefits, auto-updating patches, stat-tracking, achievements and the ability to join and invite friends through Steam's matchmaking service. As previously confirmed, Modern Warfare 3 also will support dedicated servers, which is nice.
It's not out until November, but you can pre-order Modern Warfare 3 on Steam right now. No pre-order bonuses are listed, but you'll be able to "start playing immediately upon its release on Steam," which suggests Steam versions will be pre-loadable.
