"The fans asked for a multiplayer experience and we answered," said Christoph Hartmann, president of 2K. "With Digital Extremes delivering a multiplayer experience for BioShock 2 that features all of the things that make BioShock unique, we're holding ourselves to a high standard so that we can deliver the depth and variety that fans of the BioShock universe demand."
Multiplayer in BioShock 2 provides a rich prequel experience that expands the origins of the BioShock fiction. Set during the fall of Rapture, players assume the role of a Plasmid test subject for Sinclair Solutions, a premier provider of Plasmids and Tonics in the underwater city of Rapture that was first explored in the original BioShock. Players will need to use all the elements of the BioShock toolset to survive as the full depth of the BioShock experience is refined and transformed into a unique multiplayer experience that can only be found in Rapture.
Key features:
* 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.
* FPS veterans add their touch to the multiplayer experience - Digital Extremes brings more than 10 years of first person shooter experience including development of award-winning entries in the Unreal® and Unreal Tournament® franchise.

I don't know about any of you but I think this sounds cool. I'm pretty sure when I read a interview with one of the developers a while back when asked about multiplayer he said it was in development and that they wouldn't have multiplayer achievements. I hope that's the case.
