EuroGamer - Shawn Robertson, the animation director of BioShock Infinite, is trying to remember something. "I'll double-check but I believe we have the ability to turn off the floating buildings, and that's so that people don't get seasick." Sorry, what? "Yeah, we've had a couple of people in the company who have. Don't forget this is a really big aesthetic thing - making you feel like you are in the sky - and when things float they don't stay in lockstep with each other, there's always this slightly undulating movement." In other words, welcome to the heavens - and watch out below.
