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.
No other mention of a new BioShock is contained within the article and we can find no other mention of such a title from other sources.
The last time we visited the world of Bioshock was in 2013's BioShock: Infinite, Irrational Games' swan song and last big project from creator Ken Levine. During a feature concerning Mafia III studio Hangar 13, it was revealed there was a small group of developers working on a project codenamed Parkside. According the Kotaku's report, the studio and individual devs were hit hard when they lost out on bonuses, which were contingent on Mafia III getting either an 80 or 85 on Metacritic (it ended up with a score in the 60s). "They're careful about not falling into the same problem every studio has, where they have too many people and nothing for them to do." explains one person now working on the new BioShock - at once revealing that they're still early in development, but that there's a clear plan in place for a core construct to build the title around. "It was all very tight-lipped".
Whilst the following is a stretch, signs are pointing at the secret studio being made up of Hanger 13 and BioShock-affiliated 2K Marin members. Maybe this new game is one that fans have been waiting for. "They're trying to be really smart about figuring out what the core thing is", one person involved with the project said. Take-Two CEO Strauss Zelnick has already stated that it is a permanent franchise for the company. "They're careful about not falling into the same problem every studio has, where they have too many people and nothing for them to do". In 2016, 2K Games released BioShock: The Collection, which included all three games in the franchise. Turns out, Parkside was actually referencing the next BioShock.
