Burial at Sea [Bioshock]

This story is about the DLC of Infinite (Bioshock), only Booker is alive, he wants to find Comstock and make him pay for everything he did to him in the past. He and Comstock are in the underwater city of Rapture. Except Booker knows that her friend, Elizabeth, is old or dead. Except that on his mission on December 31, 1958, while he had found Comstock, he ran into an old friend.... This story is an alternative to the DLC, I hope you like it.
This story i don't know what will happend but i hope will have what Bioshock had.
