Main Hydrochamber

Main Hydrochamber is a room in the Torvus Bog in Metroid Prime 2: Echoes. A tall and somewhat large room containing many devices operating. This is the room where the Alpha Blogg is fought. Large operational fans rotate along the walls, as well as a pillar existing in the middle of the room, destroyed when the Alpha Blogg descends. Several ledges in the room exist and can be reached with the Gravity Boost. There are also Spider Ball Tracks up against a wall leading up to a Portal.

The Dark Aether version of this room was the Undertemple.
