BioShock 3 could also take place in the underwater city of Rapture, says 2K Marin.
Speaking with OXM, creative director Jordan Thomas said that Rapture is “so core to BioShock it has to feature in some form. It’s one of the characters we don’t want to let go.”
“I think Rapture remains fertile for as much expansion as a team sees in it,” he said. “I absolutely believe that there might be future games set in Rapture in whatever time period, but I would also say that I think that the BioShock brand is big enough that it could evolve.”
In the interview, Thomas also said that BioShock 2 contains unspliced NPCs that you will interact with.
“With BioShock 2 we’re actually going to make sure that you have some strong and unforgettable encounters with unspliced characters that you can develop genuine empathy for, who will not be trying to hide their face from the camera,” he added.
