Announced back at E3 2011, Irrational Games has been reluctant to discuss PS Move support in the PlayStation 3 version of BioShock Infinite, due to the difficulty in describing how it works exactly. According to BioShock Infinite's Director, Ken Levine, talking about it is like "talking about music".

"Talking about Move support is like talking about music," Levine explained to Eurogamer. "It's hard to do. You've got to put the thing in somebody's hand and say, 'here's our Move support. How does it feel to you?'

"We're definitely going to be doing that at some point. But it's hard to talk about because it's like, 'hey, does it feel good? Does it feel right? Does it break down barriers of interface for you?'

"That's the goal of Move, right? It's to make you forget you're playing with a controller. It's to make that much more transparent. The proof's going to be in the pudding."

Levine also confirmed that PS Move will obviously be an optional control method for BioShock Infinite, and it'll be available out of the box on its launch day, which is October 16th in North America and October 19th in Europe.
