COD: MW2 UK's best-selling game ever
Headshots Dr Kawashima's Brain Training.
Activision's Call of Duty: Modern Warfare 2 is the UK's best-selling game of all time, stats from GfK ChartTrack reveal.
It overtook Nintendo's DS puzzler Dr Kawashima's Brain Training as the biggest selling UK title ever in terms of units in just 41 weeks.
Infinity Ward's monstrously popular first-person shooter spent only three weeks outside the all-formats top 10.
Dr Kawashima took around 36 months to overtake the previous record holder, Rockstar's PlayStation 2, Xbox and PC hit Grand Theft Auto: San Andreas.
Activision hopes to go one better than Modern Warfare 2 with Treyarch's Call of Duty game, Black Ops, due out this November.
