Crysis 2 and the Nintendo 3DS both disrupted the steady order of the UK all-formats charts last week, with Crytek's showcase shooter taking top spot in software. According to Chart-Track, the distribution of sales across formats for Crysis 2 gave 57 percent to Xbox 360, 29 percent to PS3 and 14 percent on PC -- of course, the company doesn't account for digital distribution, which would likely alter the PC figure.

Other chart-topping debuts last week included Lego Star Wars 3: The Clone Wars in second and The Sims: Medieval in seventh. The 3DS premiere helped launch Super Street Fighter 4 3D Edition, Pilotwings Resort and Rayman 3D into the overall top ten, with Capcom's portable fighter winding up in fourth as the most popular launch title for the system. The 3DS version of Lego Star Wars 3 was the fifth most successful title for 3DS, just below Super Monkey Ball 3D.

Meanwhile, last week's chart-topper, Homefront, lost a little ground and fell back to third place. Check out the UK top ten after the break.
