Portal 2 and Mortal Kombat top UK sales charts

Portal 2 has emerged as the best-selling video game in the UK last week, with fellow new release Mortal Kombat taking the number two spot.

Despite the PlayStation 3 version of Portal 2 featuring exclusive cross-format support with the PC it accounted for only 35 per cent of sales, with the Xbox 360 on 54 per cent and the PC on 10 per cent. The latter though does not account for digital sales.

The addition of Sony-exclusive character Kratos, from God Of War proved to have more impact on sale of Mortal Kombat though - with the PlayStation 3 version selling 54 per cent compared to the Xbox 360's 46 per cent.

As a result the Xbox 360 version of Portal 2 was the best-selling individual format title of the week, followed by Mortal Kombat on PlayStation 3, Mortal Kombat on Xbox 360 and Portal 2 on PlayStation 3. Previous number one Zumba Fitness ranked number five.

The other major release of the week was Operation Flashpoint: Red River, which made its debut at number six. Codemasters' team-based shooter saw 70 per cent of sales on the Xbox 360 and 30 per cent on the PlayStation 3.

The only major new release not to break into the top 20 this week was Sony's SOCOM: Special Forces (aka SOCOM 4) at number 28, although a number of older titles did continue to move up the charts thanks to retailer promotions.

Call Of Duty: Black Ops rose six places to number three, while Wii Fit Plus was up 11 places to number nine. Wii Sports Resort also re-entered the charts at number 14.
