A highly intriguing trailer involving the possible sequel to 2K Games' epic FPS BioShock has leaked on the internet. Supposedly tucked inside the PS3 version of the game is the teaser for BioShock 2: Sea of Dreams. It's shaky cam, shot-off-the-screen style, and, like everything on the net, it could be fake. But it looks pretty real to us. Pretty real and pretty awesome. Love that 40s jazz!
