Main Ventilation Shaft Section B is part of a network of ventilation shafts in the Frigate Orpheon in Metroid Prime that Samus travels through after the Parasite Queen battle in order to escape the frigate. This section opens out into a room with 2 Auto Defense Turrets at one point.
The room remains relatively intact after Orpheon crashed into the Tallon Overworld. A large rock wall has broken through part of the shaft. Both Auto Defense Turrets are both still active and are in fact stronger than before. A Sap Sac is found connected to the rock wall. The door leading to the hallway leading to Main Ventilation Shaft Section A was de-energized, requiring Samus to shoot a Power Conduit above the door with the Wave Beam.
- Sap Sac
- "Species: Sap Sac
- Chemical reaction within sac produces mild explosion when agitated."
- For some reason, the Sap Sac that appears in this room after the crash doesn't provide Samus with the same scan as most Sap Sacs and doesn't download its entry to the Logbook. It is possible that a logbook entry was not originally intended to be given to Sap Sacs, and that the developers forgot to change this specific Sac's scan.
