Ken Levine has admitted he's keeping "large chunks" of BioShock Infinite's story secret from his own team, in order to properly gauge their response to its twists and reveals.
Speaking in this month's PSM3, on sale tomorrow, Levine revealed: "I want to preserve [it] and observe [the team], so I can see their reactions. Keeping people virgins to that content is really important because you never get that reaction from someone a second time."
In a broad and revealing interview, he goes on to confess that keeping the story back from the team hasn't necessarily proved popular: "I think (it's) a frustration on the team here. I don't want them to know the game story, and they want a document from me that tells them the whole game story.
"I'm not going to do that. That's not the way we present stuff to the gamer. We don't ship a document. The story is only relevant in terms of how you present it, not the details of what it is.
"I don't want to send out a document which is the game story, because to me that's not the game story - that's an outline or a blueprint for us to build the game story from."
