Today 2K Games sent out the launch trailer for their undersea shooter BioShock 2. Like the best trailer from the first BioShock, this one's almost entirely in the first-person perspective.

While you fight Big Daddies in the first game, this time you are one. You're Subject Delta, a more advanced version of the Big Daddies that has woken up in the underwater dystopia of Rapture with no memory. As you travel through the city to rescue Little Sisters, you'll have to fend off dangerous new enemies known as the Big Sisters. I promise this all makes sense in the context of the game.

BioShock 2 hits stores on February 9th for the PC, PS3, and Xbox 360. A list of midnight launch locations can be found here.
