Quite possibly one of the most anticipated games of 2009, BioShock 2 has finally been given a set date from publishers 2K Games. Set for a simultaneous release on the Xbox 360, Playstation 3 and PC on October 30th 2009 internationally, while North America will have to wait another few days for their release on the 3rd November.

Take-Two Interactive today clarified a number of release dates for its upcoming titles, and officially confirmed that a sequel to 2K Boston and 2K Australia's underwater shooter BioShock will arrive during the company's fiscal fourth quarter in 2009. The publisher revealed that Gearbox Software's Borderlands (PC, PS3, X360) and 2K Czech's Mafia II (PC, PS3, X360) are positioned for release sometime in Take-Two's 2009 fiscal year, which runs from November 1, 2008 through October 31, 2009. Additionally, Rockstar San Diego's Midnight Club: Los Angeles (PS3, X360) was confirmed for release in the company's FY2008 fourth quarter, pinning the title's release window between August 1 and October 31, 2008. Back to BioShock 2, the game is under development by the Novato, California-based studio 2K Marin. The new development house is rumored to consist of several former 2K Boston and 2K Australia employees. The publisher also announced that BioShock creator Ken Levine will be involved in the development of the sequel, though his role on the project was not specified.

Bit-tech reports that a new 2K Games studio is being founded specifically for the development of BioShock 2. The new studio, 2K Marin, will consist of the remnants from the 2K Boston developer team of the first BioShock. Apparently, not many of the original staff wanted to work with Ken Levine ever again after the first BioShock. 2K Games understood the sentiment and allowed the staff to set up a new studio so they can work on BioShock 2 while leaving Ken in 2K Boston with Project X which has been confirmed as being a new X-Com game.
