Undertransit One is a room in Dark Torvus from Metroid Prime 2: Echoes.
The room is a long tunnel that only the Morph Ball can fit through. It has a series of pipe that must be navigated to get through the tunnel. There is also a hidden section that contains a Missile Expansion. There is also a lunching system that Samus enters and is fired into the pipes section.
