It's been a long time since BioShock 4 was talked about in any official capacity. All the way back in December 2019, publisher 2K officially confirmed that a new BioShock entry was in development at new studio, Cloud Chamber. It's been almost total radio silence since then, with no official news coming from either Cloud Chamber or 2K aside from a handful of job listings from last year that simply confirm the sequel is still in active development.
