Sources say that Activision is having Sledgehammer Games assist with the making of Modern Warfare 3. The title is reportedly set to come out this November, even though it hasn't been officially announced yet. Infinity Ward and Sledgehammer are splitting duties on the single-player campaign. Meanwhile, Activision has also pulled in Raven Software to work on the online multiplayer component.
Completing the game on time is a top priority for Activision, which has used the annualized Call of Duty series as one of its most reliable sources of revenue. In 2010, Call of Duty: Black Ops sold 12 million units.
It's unclear what Activision's plans for the franchise might be after this year's installment. We had thought that Sledgehammer's spin-off could be on the schedule for 2012, but if the production hasn't started yet the studio would have to scramble to finish in time.
