Storage Depot B is a small room in the Phazon Mines. It appears in Metroid Prime.


This is the room where Samus finally regains the Grapple Beam after losing it on the Frigate Orpheon much earlier in the game. To get into the room, Samus must possess the Power Bombs, since she must destroy a wall of Bendezium blocking the final Rotation Control Unit that gets her to the final and highest floor in Ore Processing, with the door to this room. More Bendezium covers the door, and after destroying it, Samus can collect the Grapple Beam.
