In an extremely surprising move, Guitar Hero 5 in its debut week on sale has denied The Beatles: Rock Band the opportunity to take the No. 1 spot on Chart Track’s All Formats Software Sales Chart for the UK, by claiming the position for itself.

This is the first time a Guitar Hero game has reached the top spot in its first week on sale.

Colin McRae: DiRT 2 also denies The Beatles an elevated position on the chart, as the excellent rally racing game sits at No. 2 this week in its first week on sale. Batman: Arkham Asylum, despite a 60% drop in sales, charts at No. 3, while only at No. 4 do we see the appearance of The Beatles: Rock Band, which is the highest debut spot achieved by a Rock Band game yet

Usual suspect Wii Fit and Wii Sports Resort show up at No. 5 and No. 6, down from No. 4 and No. 2 last week respectively, while IL2 Sturmovik: Birds of Prey (3% sales drop) manages to hang on to a Top Ten position at No .7, down from No. 6.

Call of Duty: Modern Warfare keeps at it at No. 8, down from No. 3 last week, Mario Kart Wii reappears in the Top Ten at No. 9 from No. 12, and Ashes Cricket 2009 slips to the precipice of the Top Ten listing at No. 10, from No. 5 last week.

Other interesting movement on the chart this week includes Tiger Woods PGA Tour 10 moving out of the Top Ten to No. 11 from No. 7 last week, Fight Night Round 4 also making ‘the move’ from No. 9 to No. 12 this week, Championship Manager 2010, in a very difficult debut week, appears on the chart at No. 13, Mini Ninjas, yet another debut title, shows up at No. 15, Wolfenstein slips to No. 17 from No. 11, Section 8 debuts at No. 22, Fifa 09 drops to No. 25 from No. 16 last week, and Assassin’s Creed falls to No. 35 from No. 26.
