2K Games has some exciting updates on BioShock 2, and no, they haven't decided to change the title back to "Sea of Dreams."

2K Marin and Digital Extremes are now working on the multiplayer element together, which will act as a prequel that expands on the origins of BioShock lore.  It's promising news, given Digital Extreme's experience with FPS titles, including their work with the Unreal Tournament franchise.

In BioShock 2, players will take on the role of Plasmid test subjects for Sinclair Solutions and witness the fall of Rapture from a unique perspective.  Here are some other key features to expect, as listed in the 2k press release:

• Evolution of the genetically enhanced shooter – Earn experience points during gameplay to earn access to new Weapons, Plasmids and Tonics that can be used to create hundreds of different combinations, allowing players to develop a unique character that caters to their playing style.

• Extend the Rapture fiction – Players will step into the shoes of Rapture citizens and learn more about the fall of Rapture as they progress through the experience.

• See Rapture before the fall – Experience Rapture before it was reclaimed by the ocean and engage in combat over iconic environments in locations such as Kashmir Restaurant and Mercury Suites, all of which have been reworked from the ground up to deliver a fast-paced multiplayer experience.

BioShock 2 is currently in development at 2k Marin, 2k Australia and Digital Extremes for PlayStation 3, Xbox 360 and PC.
