Zumba Fitness and Crysis 2 both moved significantly less product last week in the UK. With only 500 copies separating the two the prior week, the 57 percent drop by Crysis 2 and the 47 percent decline by Zumba Fitness meant the latter took the lead.

It seems that "winning" the sales chart last week was all about having the lowest decline in sales, as almost every game in the top six saw a 40-something percent drop (Chart-Track speculates it was the UK's warm weather). This led to Lego Star Wars 3: The Clone Wars forcing itself to maintain third place, while Tiger Woods PGA Tour 12: The Masters climbed up two spots into fourth and Shift 2: Unleashed decelerated into fifth.

Tecmo-Koei's Dynasty Warriors 7 was the only new entry in the Top 40, button-mashing itself all the way up to tenth place. Observe the UK top ten after the break.
