Elevator (Fallout Shelter)

The elevator is a room that can be built in Fallout Shelter.

Overview
The elevator is used to move dwellers to different levels of the vault making it become necessary to expand the vault. If an elevator is built without one immediately above or below it, an extra unit will be built below the built one, unless another room is already below it.

Dwellers can move through the same elevator shaft regardless of the movements of other dwellers, i.e. dwellers can cross in the same shaft and do not have to wait for other dwellers to exit the shaft. They will wait for another dweller if they are getting on at the same level, because the game will not move the dweller until the door is shut.

Elevators take up 1/3 of the space of a normal room and cannot be upgraded.
