Transit Tunnel South is a room located in the lower level of Torvus Bog in Metroid Prime 2: Echoes. It contains a missile expansion and a Secret World that requires Screw Attack.
Secret World and Early Missile
By performing a Screw Attack on either end of the tunnel, it is possible to get out of bounds. In 100% speedruns, this is used to bypass the puzzle that leads to the missile expansion.
