According to sales data published by the NPD Group, 2K's BioShock 2, the follow-up to the acclaimed first-person shooter from 2K Boston (Irrational Games), sold over 750,000 units across the Xbox 360, PS3 and PC in the US during February (tracked January 31 through February 27).

The Xbox 360 version debuted in the No.1 position with sales of 562,900 units, while the PS3 and PC versions failed to chart in the Top 10. This leaves a further 190,000 units (approximately) to be shared between the PS3 and PC.
