Elevator (Fallout Shelter)

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

Overview
The elevator is used to move your dwellers to different levels of your 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.

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