Bioshock 2 multi-player confirmed

We had a thread about whether Bioshock should have multiplayer, I guess the developers stumbled across the former thread jk. Seriously, what I don't get is the logic of other people around here, it absolutely does not mean that if a game has multiplayer that the single player will suck. Alot of games that have excellent single player also have excellent multiplayer. I think they just added multiplayer as a bonus. I find the concept of battling in an underwater city awesome especially because you will be able to use plasmids. I never played Bioshock again after like 3 playthroughs, so added multiplayer will also make replayability possible.

MP does not necesarily mean versus. I read on some thread here it would have co-op, which is still MP. I think we should wait until we get some more concrete info on this.
