Prototype 2 launched on Tuesday in the UK (instead of a Friday, per usual) last week and leapt to the top of the charts. Despite the strong premiere, Chart-Track notes the sequel couldn't match the first week sales success of the original game. Chart-Track doesn't share raw sales numbers, but it did point out that the game had stronger sales than previous chart-toppers Kinect Star Wars and The Witcher 2.

Speaking of Witcher 2, which held the crown last week, it slipped five spots into sixth place. EA continues to have a winning cluster with FIFA Street, FIFA 12 and Mass Effect 3 holding steady close to the top of the charts, with the group maintaining spots two through four, respectively.

Prototype 2 was the only new game to break the top 40 last week. Tap your tentacle past the break to check out the UK top ten.
