Since the release of BioShock: The Collection back in 2016, we haven’t heard much about the franchise despite Take-Two promising more of the series. However, it looks like the company has been working on a project in secret.

Mafia III pushed the boundaries of video game storytelling, and left people wondering what the developers at Hangar 13 would do next. But for the past year, they’ve struggled, scrapping ideas for Mafia IV and a promising spy game. Now, who knows? My story:

According to Kotaku’s Jason Schreier when interviewing developers at Hangar 13, the developers behind Mafia III, for a story an unnamed studio was working on a new installment in the BioShock franchise codenamed “Parkside”. According to Schreier, the game is in early stages and not ready.

Among other details I learned while reporting this story: Right next to Hangar 13, a top-secret 2K studio is now working on a top-secret new BioShock game.

Since the project is being developed by an unnamed studio and in early access, it’s unlikely we’ll hear more at E3.

BioShock: The Collection is now available for Xbox One, PS4, and PC.
