I don't know why people are calling this old since this is a level that Roadbose made based on the memory of an unreleased level so it's basically a new level. That original, unreleased ICE Carbon Titan X may be old, but this version is more of a remake than it is that elusive original level. Still, it's fine for the final ICE Carbon level; it doesn't have the ominous atmosphere Diablo X has but I think it instead contrasts nicely with that level, being a blue, more structured analog to the former level.
