Microsoft and Epic have claimed the Chart Track All Formats number one with Gears of War – the fastest-selling Xbox 360 title to date.
The highly-acclaimed shooter also becomes the second fastest-selling Microsoft game ever, behind Halo 2, and is the third fastest-selling game of the year so far.
EA's Need for Speed Carbon and THQ's WWE Smackdown Vs Raw are both knocked down the charts one place to number two and three, respectively, while FIFA 07 manages to climb back up to number four.
At five is Electronic Arts' third title in the top five, The Sims 2: Pets, with Konami's Pro Evolution Soccer 6 at six and Activision's Call of Duty 3 dropping down the charts from number three to number seven.
Lego Star Wars II: The Original Trilogy holds on to the number eight position, while Bratz: Forever Diamondz leaps up the charts from number 27 to number nine thanks to the DS release. Just hanging in at number ten is Rockstar's PSP exclusive Grand Theft Auto: Vice City Stories.
The only other new releases in the top forty are Activision's Tony Hawk's Project 8 at number 18 and Square Enix's Final Fantasy VII: Dirge of Cerebus at number 28.
