Bioshock 2 multiplayer trailer

I'll admit, I'm one of THOSE people. Someone who thinks that Bioshock was an absolutely fantastic single player experience that didn't really need multiplayer to enhance it. Someone who is skeptical about the addition of multiplayer in Bioshock 2.

That being said, this new video featuring some footage of said multiplayer in action has me intrigued. A very small part of me giggles at the idea of being one of Sinclair's Solutions product testers, the housewife in particular. Running around Rapture in my blue dress and apron, like a psychotic middle-aged Alice in Wonderland, melting people's faces with pyrokinesis, could be fun.

It'll also be interesting to see what role the camera plays.

Check out the video for yourselves and let me know what you think! Can multiplayer be a possible worthwhile addition to the game or just something people will blame if the single player fails to live up to expectations?
