Irrational Games boss Ken Levine has said his studio has thus far said very little about PlayStation Move support for BioShock Infinite because of how difficult it is to describe.

Support for PS Move was announced back at E3 2011, but no one outside of the game's development is any wiser as to how it will be implemented.

"Talking about Move support is like talking about music," Levine told 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 has previously said PS Move functionality must be "firewalled off" so that players can choose to ignore it if they wish.

BioShock Infinite will be released October 19 for Xbox 360, PS3 and PC.
