Generator B Access is a room on Norion. It appears in Metroid Prime 3 Corruption.


The entrance to the Morph Ball tunnel.

This room cannot be accessed during Samus's initial visit to Norion, as Rundas brings Generator B back online for her. A month after the Space Pirate assault, Samus can access this room once she finds the Seeker Missile on Elysia.

This room consists of some gates blocking access to parts of the room, which can never be accessed at any point in the game. Instead Samus must use a Morph Ball tunnel to reach the door that leads to Generator B. Near the door to Generator B, there is a gyroscopic ring system that is offline. Scanning it reveals that it was once part of an energy production unit and appears to have been shut down.
