BioShock 2 debuts at the top of UK charts, Mass Effect 2 takes a fall

2K’s return to the underwater utopia gone wrong has thus far been a successful one; BioShock 2 has debuted at the top of the UK sales charts, leaving behind Ubisoft’s power dancer Just Dance and EA’s FIFA 10.

Modern Warfare 2 has taken a stumble from third to fourth place and last week’s number one, Mass Effect 2, fell to number eight following a 58% drop in sales. Last week’s newcomer Dante’s Inferno dropped from fourth to eighth while Sega’s Bayonetta made a bit of a comeback, jumping from 38 to 10. Top 20 follows.
