BioShock 2 begins on New Year's Eve, 1958.
Subject Delta, a Big Daddy, patrols Rapture with his Little Sister Eleanor.
Delta awakens in 1968, resurrected by a Little Sister under Eleanor's direction.
Delta is informed by Brigid Tenenbaum, the custodian of the rehabilitated Little Sisters, that because he has a physiological bond with Eleanor, he will die unless he finds her.
