The next instalment in the BioShock franchise is reportedly in production at an undisclosed 2K studio, according to Kotaku.
While the source article is predominantly focused on the turbulent development of Mafia III, the report explicitly mentions development of a top-secret project by the codename Parkside, which is allegedly a new BioShock game. If true, this would be the first all-original title in the series since 2013.
One Kotaku source claims that the team behind Parkside is keeping numbers small for the time being to avoid overcrowding. Furthermore, a number of staff members at Mafia III developer Hangar 13 tried to jump ship to the team working on the new BioShock, though many were unsuccessful.
