AMN: Speaking of the graphics engine, it's running on Unreal 2.5 right?
Ken: No, we've moved to Unreal 3, we've done a lot of modifications on top of it, all the water effects we've added, and we've added a lot of features like water....again we don't build features just to have them, we build them to have an emotional resonance. The AI relationship with the characters is an emotional thing and with the gameplay, the water, we want to make you feel like the ocean is about to drown you, it's drowning Rapture and as you'll see in the demo, water is just coming into this place so we've hired a water programmer and water artist, just for this game, and they're kicking ass and you've never seen water like this.
AMN: When did the change happen, the switch to UE3 happen?
Ken: A few months ago, I mean, technically, I think you misunderstand me on how this works, basically, we translated systems over and ported more systems over, but Unreal 3 has a lot of elements that 2.5 has, there's a lot of marketing there, but we had a lot of benefits to that and we're not using all of it, we're using our own things, but we have a lot of benefits too.
