It appears that 2K Games snuck in some extra content into the newly released PS3 version of BioShock. Upon beating the game, PS3 players unlocked a hidden trailer of BioShock 2, which will be titled “BioShock 2: Sea of Dreams”. The trailer shows a Little Sister (which no longer looks “little”) staring out to see while clinging onto a Big Daddy plush toy. Then, a city erupts out of the sand. Can’t wait for the Xbox 360 version. Video after the jump.
