With last week being not particularly big on new releases, the charts have hardly been set alight, with Dead Island's Game of the Year Edition being this week's highest new entry. But it's an 81% increase in sales, as the Olympic Games approach that's resulted in this week's number one, with London 2012: The Official Video Game now taking the podium.

LEGO Batman 2: DC Super Heroes manages to stay near the top of the charts too this week, despite a 30% decline in sales, while The Amazing Spider-Man and Spec Ops: The Line also take a hit, with sales falling by 15% and 24% respectively. Both games manage to stay where they are, however.

Meanwhile, this week's biggest winner is Call of Duty: Modern Warfare 3, which storms back into the charts with a rocketing 193% rise in sales, thanks in no small part to the recent half-price DLC. This has no doubt helped Black Ops retain a spot in the top 20 too. Check out the top 20 here:
