BioShock Infinite At the start of
Infinite, set in 1912,
Booker DeWitt is sent to Columbia by the
Lutece twins to recover Elizabeth, claiming that they will wipe away his debts with her return. Booker is quickly discovered as the "False Shepherd" that will take the Lamb away, and is set on by Comstock's troops. Booker frees Elizabeth, and both narrowly avoid an attack by Songbird that destroys part of the statue. As Elizabeth accompanies Booker, she discovers that her abilities to find and manipulate tears have grown stronger, and uses them to help Booker fight through Comstock's troops. Elizabeth is initially doubtful of Booker's intentions, but comes to trust him over the other residents of Columbia. When trying to track down a man who reportedly holds a key to helping them escape, they find the man already dead; Elizabeth uses her powers to pull them into an alternate reality where the man is still alive, but this has unintended side effects in that others around them suffer from nosebleeds and mental anguish, and Elizabeth becomes fearful of her abilities. They eventually board an airship to escape, but it is brought aground in Columbia by Songbird, who kidnaps Elizabeth. Booker gives chase, but is pulled into the future of 1983 by an elderly Elizabeth. She shows him that without his rescue, she will become like Comstock, inheriting the city and using it to lay waste to the surface world below. Before allowing Booker to return to his time, the future Elizabeth gives him a message to give to "his" Elizabeth to help her control Songbird and allow them to escape. Booker frees Elizabeth from an observation laboratory and the two make their way to confront Comstock. Along the way, they learn that Elizabeth has been kept under control of the Siphon, a machine built by the Luteces into the statue to nullify her tear powers; they also learn that Elizabeth is not Comstock's biological daughter, though oddly shares his genetics, and Comstock killed his wife and attempted to kill the Luteces to hide this conspiracy. They reach Comstock and Booker confronts him about Elizabeth's identity. Comstock says Booker already knows it and the reason for why Elizabeth wears a
thimble in place of her little finger. Booker kills Comstock in anger, but Elizabeth calms him down and says they need to finish destroying the statue and the Siphon to fully realize her powers. They do so by controlling Songbird, but when Songbird turns on them, Elizabeth transports them to the underwater city of
Rapture, where Songbird is destroyed by the outside water pressure. Elizabeth guides Booker to the bathysphere lighthouse, revealing she can now see all possibilities based on choice as evidenced by an infinite number of lighthouses they can see. Elizabeth explains the nature of choice to Booker, revealing that Booker and Comstock are the same person: in one reality, Booker ran away from a baptism ceremony after his atrocities at the
Battle of Wounded Knee, while in another, he accepted it and became the religious Comstock. Elizabeth reveals she is also Booker's daughter, Anna DeWitt, whom Booker had sold to the Lutece twins to pay off gambling debts. They in turn were working for Comstock, who needed a blood heir for Columbia, having been rendered sterile by the twins' reality-warping experiments. Booker later had a change of heart and chased down the Luteces as they stepped through a Tear, severing the tip of Anna's finger, which gave her awareness of multiple realities. Elizabeth asserts that there has been an endless cycle of Bookers and Comstocks, and the only way to end this is to prevent the creation of Comstock; she takes Booker to the site of the baptism and drowns him with the aid of other Elizabeths from alternate timelines. The Elizabeths begin to wink out of existence, with the game fading to black on the one throughout the game.
Burial at Sea In
Burial at Sea, Elizabeth approaches Booker – in this reality, a private detective in Rapture – to help them find a missing girl named Sally. They trace her whereabouts to a derelict department store, during which Booker suffers flashbacks to his baptism, but unable to explain them. When they finally find Sally, they find she has been changed into a Little Sister, and Booker suffers more flashbacks, recalling his daughter Anna, before becoming aware of his true nature: he had been one of the Bookers that became a Comstock, but in his attempt to get Anna from another Booker, she was killed. In his remorse, this Comstock reverted to his birth name of Booker DeWitt and had the Lutece twins transport him to Rapture, a reality where neither Anna nor Columbia existed. Elizabeth makes sure that Comstock is killed by a Big Daddy before she passes out. When she comes to, she finds Atlas has Sally and demands she help them escape the store to return to Rapture in exchange for her. As she sets out to do this, she is guided by visions of Booker, and later learns that she herself had died earlier in Rapture; she made a deal with the Lutece twins to combine all her quantum selves and memories of future time into one mortal body to return to this place at this time to rescue Sally, effectively leaving all alternate versions of herself in their own respective universes. She struggles with this, and further learns that Dr. Suchong of Rapture had worked with Jeremiah Fink from Columbia to collaborate on technology. Suchong forces her to briefly return to Columbia via a tear to obtain a Lutece particle that will raise the sunken Rapture building, where she further learns that the Luteces had convinced Daisy Fitzroy to threaten Fink's child to make Elizabeth kill her as to mature her. She returns and amid an attack by Andrew Ryan's men, completes the task. Atlas launches his war against Ryan and tortures Elizabeth in an attempt to extract the location of his "Ace in the Hole". In a flash of panic, she is able to remember the location, and Atlas makes her go retrieve it. The Ace is revealed to be a piece of paper with a coded message. She willing gives it over to Atlas knowing that he plans to kill her, but is privy to one last memory from before - that of seeing Jack on the plane that would crash near Rapture, and the note containing Jack's trigger phrase "Would you kindly". Atlas uses this to start his last attack and fatally strikes Elizabeth's head one last time. Elizabeth dies holding Sally's hand, smiling in knowing
Jack will soon come to help the children of Rapture escape the violence. ==Promotion and reception==
