The Sacrificial Chamber Tunnel is a room in the Dark Torvus Bog. It appears in Metroid Prime 2: Echoes. It simply serves as a connection between Sacrificial Chamber and Undertemple Shaft. Half of the room is occupied by a large patch of a mutant strain of Venom Weed, and the other by Ingsphere Caches.

The Aetherian version of this room is Training Access.
