No co-op but
Multiplayer
2K Games has tapped Unreal contributor Digital Extremes to create a multiplayer mode for BioShock 2 that is every bit as rich and detailed as the single player. Players take on the role of a plasmid test subject for Sinclair Solutions during the fall of Rapture, allowing them to experience yet another aspect of the underwater empire's history as they progress through the multiplayer experience. Iconic locations like the Kashmir Restaurant and Mercury Suites are being reworked from the ground up in order to facilitate a fast-paced multiplayer experience.
Speaking of experience, players will gain experience as they play through the multiplayer portions of the game, earning them access to new plasmids and tonics. With hundreds of different combinations available, players will be able to develop their own particular play style, which should lead to some very interesting battles.
Glad they are going with different littlesisters look
