Activision's hugely popular Modern Warfare 2 has unlocked a new achievement – over 20m copies of the game have been sold since release.
CFO Thomas Tippl revealed the news to investors at the publisher's E3 2010 conference. He said: "Modern Warfare 2 has sold more than 20m units against an install base of 55m on Xbox 360 and PS3."
CEO Bobby Kotick added: The Call of Duty franchise has reached life-to-date revenues of $3bn.”
The game was originally released on November 10th last year on Xbox 360, PS3, PC and DS and went on to become the best-selling game of 2009.
Activision has since released a DLC expansion pack consisting of five extra maps for Xbox Live and PSN. The next Call of Duty title – Black Ops – is scheduled to hit retail on November 9th this year.
Kotick also told investors at last night's E3 event that he wants Activision to take a slice of the $3bn pre-owned market.
