Modern Warfare 2's Stimulus Package has been bought over 2.5m times in just one week.
That's just on Xbox 360, remember, where the five extra maps cost 1200 Microsoft Points (£10.20/€14.40).
Microsoft added that 1 million people had snapped-up the Stimulus Package in 24 hours alone.
Infinity Ward's Robert Bowling revealed on Twitter last night that Modern Warfare 2 players had invested over 1.75 billion hours - over 200,000 years - into the game since release (November 2009).
The Stimulus Package was released last Wednesday and was soon discovered not to be working. The internet went nuts and Microsoft eventually fixed the problem.
Coincidentally, Microsoft soon revealed a compensation-like reward for all Xbox 360 owners that bought the Stimulus Package, offering them seven days of extra Xbox Live Gold membership.
No date has been set for the Stimulus Package on PC and PS3.
