ELSPA has awarded Modern Warfare 2 its highest accolade in the form of a diamond sales award.
The Xbox 360 version of the game has become just the 16th to receive the award, which is given to games selling over one million in the UK.
Modern Warfare 2 remained at the top of the all-formats chart for a third week this week, and its first week sales totalled over 1.7 million units.
While the 360 game has sold over one million since release, triggering the diamond award, the PlayStation 3 game has been given a double platinum award for sales of over 600,000.
Other games that share the diamond award include Dr Kawashima's Brain Training, New Super Mario Bros, Wii Play, Mario Kart Wii and Halo 3, as well as Call of Duty: Modern Warfare on Xbox 360.
