Speaking in an interview with Giant Bomb, Ken Levine speaks a bit about Bioshock Infinite, the persistent themes and what they're doing to kick it a notch. One of the things they're focusing on is stepping up the interaction between the AI.
"In videogames, everything is always amped up to eleven, and you can always have them do bigger and bigger things," he said.
"Sometimes, we were like: 'How do we demonstrate that this guys is just fucking badass?', and the notion of grabbing a horse while running "“ and that's a technologically a very difficult thing to do, because having a guy grab another guy that's moving, that's really challenging.
"In the original BioShock, where the Big Daddy would pick up the Little Sister and put her behind him, I wanted a level of interactivity between AI because generally the AI really doesn't interact with each other in a meaningful way. But what we're really focused on in Infinite is interaction between AI and really stepping that up, and really making them do interesting things together.
"You don't see a lot of that, and it's hard to do but we're always always looking for things people haven't beat to death already."
