There are more than 500 developers working on mega-brand Call of Duty, Activision has revealed.
That number represents the combined work of multiple studios - "It takes a village in this case," Activision Publishing executive vice president Dave Stohl told GamesBeat.
Upcoming Call of Duty game Modern Warfare 3 is a collaboration between Infinity Ward and Sledgehammer Games. Sledgehammer Games had been making a third-person Call of Duty action adventure before being roped in to work on MW3.
Singularity developer Raven Software is also helping out with downloadable content, as it did with DLC for Call of Duty: Black Ops.
Demonware, the Activision-acquired multiplayer middle-ware company, makes the network code for the Call of Duty series.
That's seven studios all involved in Call of Duty.
The marketing team must be pretty big.
