Electronic Arts' Mercenaries 2: World in Flames has done it again. It sits pretty at the top of the UK All Formats Chart once more.

In fact, Electronic Arts has done it again thrice-over. The Top 3 from last week is unchanged. Tiger Woods PGA Tour 09 is still at Number 2, while Spore is still sat being all godly at Number 3.

That's not to say that they've all performed quite so well as they did last week. Mercs 2 has dropped 5% of its sales, Tiger Woods lost 9% and Spore shed 23%.

Guess what's back in the Top 5, though. It features the improbable athletic pairing of a super-fast blue hedgehog and a tubby plumber. Yup, SEGA's Mario & Sonic at the Olympic Games. The game is up at Number 4 (from Number 8), with Chart-Track crediting “promotional activity” for the impressive 85% sales leap.

Nintendo occupies the next two spots, with Wii Fit dropping one place to Number 5 and Mario Kart Wii remaining at Number 6, despite a 17% sales jump.

Take-Two's Carnival Funfair Games drops two places to Number 7, in spite of a 3% sales jump.

Activision’s Guitar Hero: On Tour makes an impressive ten spot leap from Number 18 to Number 8, complete with a 143% sales increase. This, again, is thanks to additional promotion.

The only new entry of note is Midway's TNA Impact!, which hits the Chart like tiny lycra pants fired at great speed, landing at Number 9 on the 360, PS3 and PS2.

Next week, watch out for LucasArts' The Force Unleashed, EA's Crysis Warhead and Warhammer Online as well as SEGA's Yakuza 2 on the good old PS2.
