GamesRadar: What environments did the team dream up that didn't make it into the final game?

HP: We had a whole zoo! Fort Frolic was originally going to be like Disney World, a full amusement park. We built a Ferris Wheel for it and there was going to be a zoo with all these sea creatures and land animals. Rapture was going to be a fully fleshed-out city with everything you could possibly imagine. Can you imagine seeing elephants in cages down there, under the water?

GamesRadar: So the animals would have been still alive?

HP: Of course they would have! Then you would get to ride one… [laughs] You know, the plan didn't go too far. It was just in everyone's imagination and then the realities of production and timeframe have to take over at some point. We always tend to bite off more than we can chew here.
