ChartTrack reports that Activision’s Call of Duty: Modern Warfare 2 has made it nine weeks straight at the top of the All Formats All Prices UK video game chart. Last week the game became the third biggest-selling game ever in the UK, behind Brain Training and GTA: San Andreas.

Wii Fit Plus climbs one place to No.2, Ubisoft’s Just Dance jumps four places to No.3 and Wii Sports Resort holds strong at No.4. The week’s highest new entry is SEGA’s Bayonetta at No.5, beating THQ’s Darksiders which managed eighth place.

Look out for a strong new entry from EA’s Army of Two: The 40th Day next week, but will it be able to topple Modern Warfare 2?
