BioShock 2 teaser site launched [Update]

[Update - Looks as though more stuff's been found on the site.]

2K's put up a BioShock 2 teaser site, as seen here.

SomethingInTheSea.com doesn't tell much of the game. It shows a cross on a map of the west Irish coast, and shows a picture of a Big Daddy doll.

Thanks, Joystiq.
