Those PS3 owners lucky enough to escape from Rapture in that console's version of BioShock are in for an exclusive little treat, GamePro has learned Thursday.

According to NG4, the exclusive is some new content that appears in the extras menu after the game is completed. What is it? The cool video above, which serves as a teaser trailer for BioShock 2: Sea of Dreams.

The video shows a grown-up Little Sister, clutching a Big Daddy doll, on the Atlantic Coast. Then things get... a little weird, as sand castle buildings begin to sprout up from the beach. Cue the BioShock 2 logo and that's it.

What's it mean? Who knows for now. Just get ready to hit the beach.

UPDATE: In other news, this not-even-out-yet title is going to receive a launch day patch to fix blocky Big Daddy's.
