Trial Tunnel

The Trial Tunnel is a room in the Dark Agon Wastes. It appears in Metroid Prime 2: Echoes.
==Description==
While its name would suggest the presence of a Morph Ball tunnel, the room is quite small. Evidence suggests it was intended to be much larger, however (see below). In the center of the room is a Dark Temple Key, and to the right of that is a Light Crystal, projecting a Safe Zone that envelops the room. It is accessed just off of the Dark Agon Temple entrance, by heading to the left from the Dark Agon Temple's locks.
The Aether version of this room is the Mine Shaft.

==Development notes==
Using out of bounds or free-movement camera reveals that this room is much larger than initially seen. True to its name, it features an unused, inaaccessible tunnel that appears identical to the one in the Mine Shaft, the Trial Tunnel's Light Aether counterpart. The Morph Ball tunnel, positioned behind the Dark Temple Key, is functional but blocked off by a solid wall. Using out of bounds cheats, it can be accessed. No enemies are present, and only the single Pit Block leading quickly to the lower part of the shaft remains and is usable. The camera actors inside the tunnel are either not rigged properly or absent, making Samus's travels inside the tunnel in Morph Ball somewhat confusing. A lower entrance is present and oddly also blocked off by a sand wall.
A Safe Zone is present, despite Samus never entering the area under normal circumstances. An empty doorway is also present and when Samus walks through it, the game correctly loads the connecting room Trial Grounds. On that side of the room, Ingworms block the door, preventing access to the Trial Tunnel's lower half. All of this suggests that the room was originally intended to play a much larger role, with the alternate exploration layout most likely built around the acquisition of the Dark Temple Key.
