Activision’s announced that its repertoire of DLC-based Call of Duty map packs have surpassed the 20 million download mark. The firm cites internal figures across Xbox 360, PS3, and PC.

“The Call of Duty franchise is unique in the world of entertainment and delivers one of the best multiplayer experiences ever,” said Robert Kotick, CEO of Activision Blizzard. “We are thrilled to deliver to fans exciting and engaging content that has the intensity they have come to expect from the franchise.”

At the premium price of $10-15 a pop that Activision charges for these packs, that’s a staggering amount of green. Clearly a significant source of revenue for Activision. There’s little doubt that we’ll see more DLC soon following the eventual release of Black Ops in November.
