Central Area Transport West
Central Area Transport West is a room located in Sanctuary Fortress in Metroid Prime 2: Echoes. It contains a Missile Expansion and [Secret World]. The room has two different systems for passing it. If going from the top of the room to the bottom, Samus needs to go through a network of Morph Ball tunnels, where the missile expansion is located. If going from the bottom of the room to the top, Samus must use the Kinetic Orb cannons, which automatically move all of the central platforms out of the way for a short time. The first Kinetic Orb cannon is locked by an echo bot, which requires Echo Visor to take care of. The echo lock is activated by a trigger near the door to Main Research.
By Screw Attacking into the tunnels, it is possible to get Out of Bounds.
