Storage Depot A

Storage Depot A is a room in Metroid Prime in the Phazon Mines. It is where you obtain the Grapple Beam again. To get to this room, you will have to be in the room next to this room. You will have to go through a maze with Spider Ball tracks. There is a Bendenzium thing in the way showing that you need the Power Bomb to get through the maze. Once you've gotten the Power Bomb, then you are going to be fine during the maze. Then after the maze, you will finally be able to enter this room and finally get the Grapple Beam again.
