Levine, answering questions on a Reddit “Ask Me Anything,” said it was too early to tell if Irrational will be working on a BioShock 4, but that inspiration for a new iteration of the series always depends on an idea they fall in love with and excites them.
“If we don’t have that, I suspect it would be another studio making one, if there was one to make,” Levine said. “But I can’t imagine doing it if we weren’t in love with the idea.”
Levine also revealed that if what makes a BioShock game was Rapture, there would be no Irrational BioShock game coming out.
Irrational moved away from Rapture in BioShock: Infinite, Levine said, because when determining what makes a BioShock game early in development, the city under the water didn’t necessarily need to be there.
“After a lot of soul searching, we determined (what makes a BioShock game) was A, the game takes place in a world that is both grounded in reality and fantastical at the same time. That world needs to be more detailed than any other game world out there,” Levine said.
“B, the combat has to have a strong improvisational nature, with a suite of player tools that lets everyone approach combat differently.”
The BioShock: Infinite two-part DLC Burial at Sea should be available to download before the end of the year.
