It has been years and years since the events of BioShock 2! The underwater city of Rapture has descended only into the annals of the myths of mankind. However, a independent journalist, Peter A. Floyde, is reporting for his independent news network, PopulistTV, which is dedicated to revealing the truth behind government sponsored or corporate sponsored news! Peter's report on a strange incident leads him to the home of a 83 year old woman who claims she knows about the long lost city of Rapture, and she actually lived and survived after the Civil War and escaped Rapture along with other people! At first, Peter thinks that there's no credibility to the story, but after thousands of luggage trunks and suitcases from Rapture wash ashore on a Southern California beach, Peter decides to descend to the very bottom of the ocean to rediscover what the 83 year old woman called Rapture: Poseidon's Hell!
