Below we have prepared a walkthrough of Chapter 40 of BioShock Infinite - the Sea of Doors (Epilogue). This is the last chapter of the game. You can finally conclude the whole story.
This chapter serves as an epilogue. All you have to do is to remain on the path and to listen to what Elizabeth is telling you to do.
You can't get lost or make any mistakes here and you also can't influence how the game's going to end (the game has only one ending available and it is displayed regardless of previous small choices), so just enjoy the grand finale.
