This is since the release of Call of Duty 4: Modern Warfare.
According to Infinity Ward, there are roughly 100 million people who have played Call of Duty, which is larger than the population of countries like Germany, France, UK and Italy. Roughly 32.3 quadrillion shots have been fired till now with 31 billion care packages called in for since Modern Warfare 2. Over 5 billion cars have been destroyed in the game and players have spent a total of 25 billion hours or 2.85 million years playing the Call of Duty.
Which is apparently longer than the entirety of human existence. Oh, the humanity (literally).
Will such numbers help Infinity Ward with its next release, Call of Duty: Ghosts? We’ll find out when the game releases worldwide on November 5th for Xbox 360, PS3 and PC, with Xbox One and PlayStation 4 releases due for later.
