Looks like the PS3 version of BioShock has more on it than just a few extra levels. One user has revealed a secret trailer for BioShock 2: Sea of Dreams that unlocks when you complete the game on the good ending.
Looks like the trailer shows a little sister slightly grown up and holding a big daddy doll. She appears to be causing the sand to create a mini Rapture. Oh spooky.
Could this mean the little sisters you brought with you to the surface have passed something onto their daughters? Something sinister?
And what's the significance of the butterfly on the title screen at the end?
So many unanswered questions, but I'm just happy to see a trailer for this new BioShock game.
