Chart-Track, Portal 2 was actually Valve's first ever all-formats chart topper -- the closest the company ever got to the crown was with The Orange Box, which reached third place.
Call of Duty: Black Ops "price promotions" in the region caused Activision's behemoth to jump back into the the top three, followed by last week's chart topper, Zumba Fitness, which still increased sales by 10 percent last week. The top five was rounded out by the blockheads of Lego Star Wars 3: The Clone Wars.
Operation Flashpoint: Red River also had a solid debut, entering the charts in sixth place. Check out the full top ten after the break.
