Here's a piece IGN had with him, but there was a quote that caught me off guard.
“One of the things I’m most excited for in the first DLC is that the first half of it has no combat,” Levine teased. “It’s just playing in that world, you know, the Rapture you’d never really seen before, and watching Booker and Elizabeth use their wits to solve a problem and just soak in the atmosphere.”
I know a lot of you will be pleased by this since you thought Infinite stuttered with its combat. I think fuck that, what else am I gonna do instead? Bioshock isn't the type of game that relies on any other mechanics other than exploring and interacting with characters, but I don't think that's enough.
