The Portal Chamber is a room in the Dark Torvus Bog. It appears in Metroid Prime 2: Echoes. This room is almost identical to its light counterpart, except that it lacks an expansion and it has a way out of the central section through a lift off to the side. It also has several Ingsphere Caches and Dark Water instead of regular water.
