When it comes to previewing a new game, obviously a hands-on demo is the preferred scenario but watching gobs of raw gameplay footage is nice, too. Today 2K games released a nine minute video of BioShock 2.

Some of the footage was released last month but the rest of it is brand new, we swear. BioShock 2 will take place inside and outside of the underwater city of Rapture and the movie shows our brave hero walking along the ocean floor at one point. That giant diving suit isn't just for show, you know.

BioShock 2 will arrive in late 2009 for the PS3, Xbox 360, and PC.
