GR: Burial at Sea takes place after the events of Bioshock Infinite, or at least it seems that way so far. You start off in the office of Booker Dewitt, except instead of being haunted by a disembodied voice, you're greeted by Elizabeth. She has the allure of a sexy heroine from a noir detective mystery, standing at Booker's office window with a cigarette waiting to be lit. She needs Booker's help to find a girl named Sally who bears a striking resemblance to a little sister, with one catch. She has blonde hair. Booker even makes a remark that there are tons of little girls just like her around Rapture. Cue the Twilight Zone theme song.
