With rumors circulating that suggest BioShock 4 could be set in an environment unlike any other before it, the series appears due for a major shift in tone and presentation when it eventually returns. Taking place in Antarctica, as has been suggested by leakers, would be a shockingly barren departure from the more bustling locations featured in previous games. Given the history of the series, however, Antartica could ultimately subvert expectations through having sustained a vibrant and living world of its own leading up to BioShock 4's events.
