The Hyper Elevator is unlocked when you build a Refined Metals Factory. It costs 25 Machine Parts and 5 Refined Metals to build, and 200 Knowledge as research cost.
Description: "Allows citizens to go to elevators above and below in the same contiguous building. There may be other buildings in between the elevators."
Note: They only connect vertically in the same tower not the same collection of buildings.
It is one of the Three Transportation available in game along with The Teleporter and Landing Pad
