Activision today said its Call of Duty franchise has more than 40 million monthly active users across all of its titles, half of that coming from the latest release, Modern Warfare 3.
What's more, there are 7 million users in the game's Call of Duty: Elite online service, 1.5 million of them as paying annual members.
In January, Xbox Live reported that the three most recent Call of Duty titles went 1-2-3 in its listing of most popular games played on the Xbox 360. The figure concerns all users playing while logged into Xbox Live, not just multiplayer. Call of Duty: World at War and Call of Duty 4: Modern Warfare also made the top 20. Activision said both games, released in 2008 and 2007, respectively, split 5 million users.
