Portal 2 and Mortal Kombat still lead UK charts

There were no new entries in the UK multiformat top 20 last week, as Valve's Portal 2 remains the number one selling game in the country, followed by Warner's Mortal Kombat.

Although the double bank holiday meant only three normal working days for the week ending April 30th there were new releases to be had - most notably Sega's Thor move tie-in and the heavily advertised Virtua Tennis 4.

In the end though neither title appeared in the new top 20, with Virtua Tennis 4 debuting only at number 23.

Given the unusual nature of the week the 51 per cent fall in sales for Portal 2 and 42 per cent drop for Mortal Kombat cannot be directly compared to the previous week, but the drops are more than other lower-placed titles.

Codemasters' Operation Flashpoint: Red River saw only a 21 per cent decrease in sales at number four, despite a mixed critical reception.

It was denied the number three spot though by Zumba Fitness, which also saw a decline in sales of 21 per cent. The title was boosted by the delayed release of the PlayStation 3 version though, which accounted for 10 per cent of this week's sales.

According to Chart-Track the Xbox 360 version accounted for 10 per cent and the Wii version 81 per cent.
