Fungal Hall B is composed of very large Saturnines and a floor full of Phazon. There are several Tallon Metroids in this room, as well as a Glider, which Samus must grapple on to in order to progress. Because this place is very dark, the Thermal Visor can improve vision. This room connects to a Missile Station.
- Phazon Mining Tunnel (via Red Door)
- Missile Station Mines (via Red Door)
- Quarantine Access B (via Red Door)
- Missile Expansion
- At the far end of the room, there is a circle of small Saturnines. If Samus lays a bomb here, the floor will crumble and the expansion will be revealed.
