BioShock creator Ken Levine has said the amount of writing, scripting and character interactions in each area of BioShock: Infinite is three or four times greater than the entirety included in the first game.
Speaking to Eurogamer, Levine said he didn't initially consider the amount of writing it would take to get the game's main characters, Booker and Elizabeth, chatting with each other.
"When I first came up with these characters Booker and Elizabeth talking to each other and interacting with their world, I didn't consider how much writing that was going to be," he admitted.
"Just one level of BioShock Infinite writing and the amount of character interaction we have is probably three or four times as much writing as in all of BioShock 1.
"I'm doing the vast bulk of it and it really is... it can get overwhelming," he added. "But on the other hand it's a world that I absolutely love to write. Mostly because it's a new challenge. Thinking how these scenes are going to play out, how we keep them interactive and how you communicate the ideas."
Last week 2K released a new BioShock: Infinite trailer showing off the Handyman, one of the game's heavy-hitting enemies.
