Irrational Games has avoided discussing PS Move support for BioShock Infinite in detail because it's hard to explain how it works, Ken Levine has said.
Levine announced Move support for the upcoming shooter back in E3 2011, but we know nothing of how it will work, exactly.
"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."
Move support is one of two bonus features PlayStation 3 owners can expect when BioShock Infinite goes on sale in October.
The other is a free copy of the 2007 classic that started the BioShock series off - it's included on the BioShock Infinite Blu-ray disc.
As for Move support, in November last year we spotted a "special" BioShock Infinite PS Move peripheral on Sony's website, but this was later removed and the company insisted no such peripheral existed. Levine himself has admitted to being surprised by it.
Levine has, in the past, cautioned against forcing Move down players' throats.
"Any experience that sits in the realm of motion play needs to be kept separate from the main experience," he told OXM.
"It needs to be firewalled off so that if this experiment isn't for you, or doesn't turn out to be all that great, you just ignore it.
"Any new experience we add, we need to be able to protect this experience. I like the stuff they're doing with Mass Effect 3, in terms of making some of the interface aspects a little less thorny - more the squad commands than the conversation, as that's a bit of a challenge on the controller.
"What you don't want to do is add something in and enforce it on anybody. Do an experiment, fine! We're in the experimental stage, and people shouldn't be afraid of experimenting as long as we can firewall off and protect what we know works. If we don't experiment, we don't progress.
"I'm a hardcore gamer - I do most of my gaming on mouse and keyboard. I'm always open to new things, but I'm a really conservative guy at heart. I'll try it out slowly, but I'll be doing so very conservatively."
Levine confirmed to Eurogamer that Move support will be available at BioShock Infinite's launch.
