The room has no ceiling or floor, with a long drop if Samus happens to fall. A massive cylindrical Luminoth vault chamber can be entered, but it covers up an important item for further exploration: the Screw Attack. As no known weapon can penetrate the chamber, Samus must instead complete a puzzle. At the bottom of her chamber, there is an Interface Module, once scanned, a bridge lowers for Samus to use to gain access to a Dark Portal. This will lead her to the Vault Attack Portal, and she must cross the chasm using the Grapple Points to reach the other side, which contains a Light Portal. This will take Samus to the other side of the Vault, where she must jump to several platforms containing Luminoth laser turrets, arrays that will channel solar energy at the vault chamber. Samus has to operate several Spinners on the platforms to rotate them properly, and then make her way back to the inside of the vault chamber, where she can lay a Bomb in a Bomb Slot and thus cause the vault chamber to retract, giving her access to the Screw Attack.

- If Samus starts to grapple in the Vault Attack Portal, but quickly moves backwards into the Light Portal, she will reappear in the Vault, but have her arm raised in the air as if she was grappling something, although she is not.
