Hydrodynamo Station is a room in the Torvus Bog in Metroid Prime 2: Echoes. It is a large, cylindrical room that features four platforms that rotate around the central pillar. Several locks exist in the room; they must be scanned from behind to lift them and allow Samus to enter the Hydrodynamo Shaft. Samus must traverse through the connecting rooms to gain access to these locks. The Dark Aether version of this room was the Undertemple Shaft.
