Activision has announced that Call of Duty: Black Ops beat Modern Warfare 2's five-day sales record by $100 million.
Black Ops did $650m worth of business during its first five days on sale worldwide, according to Activision's internal estimates, compared to the $550m Modern Warfare 2 did during the same period after its November 2009 launch.
According to the publishers, players logged more than 5.9 million hours playing multiplayer between them on launch day, when more than 2.6 million unique gamers were busy shooting one another in the face.
If 5.6m units brought in $360m, $650m must mean the game is getting pretty close to having sold 10 million units worldwide, although Activision doesn't break the figure down so it's hard to work out what it represents.
All that and it's a wonderful game too. Happy days!
