“Take-Two’s sequel to the excellent BioShock has been revealed. N4G got the scoop via one of its readers that finished the final version of BioShock for the PlayStation 3.
After completing the game, a teaser trailer unlocked for BioShock 2: Sea of Dreams. The trailer depicts a Little Sister standing on a shoreline holding a cute Big Daddy keychain while staring out over the ocean.
The ground begins to shake leading to a sandcastle-like formation rising from the beach. It’s obvious that the structure resembles the city of Rapture leading us to believe that BioShock 2 will see the underwater structure rise from the depths. While the new trailer has yet to be officially released by the publisher, you can see a low-quality YouTube version below."
