2K Games' big-hitting sequel BioShock 2 has stamped to the top of the UK all-formats top 40.

This is the publisher's first number once since Grand Theft Auto IV in April 2008.

Last week's leader Mass Effect 2 dropped to eighth.

Just Dance held poise in second, FIFA 10 stretched to third and Modern Warfare 2 was nudged to fourth. Wii trio Wii Sports Resort, New Super Mario Bros. Wii and Wii Fit Plus followed.

Dante's Inferno was in ninth, and the top 10 was rounded off by Bayonetta, which leapt deftly from 36th into 10th.

This week's other newcomers - Star Ocean: The Last Hope (PS3) and Super Monkey Ball: Step & Roll (Wii) - entered their platform-specific charts at 11th and 19th respectively.
