You're going down into the New York subway system where some of the survivors are. The house is kinda broken into thirds. So you're seeing more human survivors, then you see them as they're mutating, and by the time you get to the end, they're all just these nasty creatures and same thing with the lighting and power. It's all solar panels and you go into battery operated and then you go down where there's no lights. Just the luminescence of strange mushrooms and subterranean things. The creature design on this one is top notch from our makeup and costuming team.
