BioShock 4 was confirmed to be in development at Cloud Chamber in 2019 (and had reportedly been in development even longer), but with publisher 2K Games having said that the game would be in the works for several more years, concrete details on it dried up following that. Recently, however, leaks have emerged with potential details on it- specifically, its setting.
In a recent Sacred Symbols video uploaded by journalist Colin Moriarty, it’s been claimed that BioShock 4 will take place in a fictional 1960s Antarctic city called Borealis. In its own report, VGC corroborates this detail, stating that it has heard the same from its own sources.
Moriarty also states that the development team at Cloud Chamber is well aware that the game will be compared to previous BioShock games and, more specifically, the works of series creator Ken Levine, suggesting that the developers are designing an experience very much in the same vein. Moriarty also claims that BioShock 4 is currently targeting a 2022 launch.
Another recent leak claimed that BioShock 4 will be called BioShock Isolation and will feature setting and story will revolve around two new cities, one on top of each other, with an announcement planned for sometime in 2022. Read more on that through here.
Previous job listings have also revealed potential new details on the next BioShock game. It seems to be using Unreal Engine 5 for its development, while listings have also made mention of an open world setting, the game taking place in a “new and fantastical world”, and a dialogue system, emergent AI systems, and more.
