BioShock 4 is a mystery game: no one has officially announced it, but the public and insiders are sure that the game is in development and, moreover, has fallen into production hell.
Perhaps no one doubts that the project from the Cloud Chamber studio will not be released in the next few years, and this version has indirect confirmation.
What is known
On the professional platform ArtStation, interesting information was found in the profile of the senior concept artist of the Cloud Chamber studio, Mack Sztaba. He indicated 2028 as the release date for BioShock 4.
Considering all the difficulties faced by the game developers, this date looks realistic. Although there are fears that the game will not be released at all.
