The Luminoth vault chamber is a large security device created by the Luminoth to protect the Screw Attack upgrade in the Vault. Composed of unusually durable Luminoth-designed alloys, it consists of a cylindrical chamber attached to a large articulated arm, with a smaller cylinder in the center of the first. This device fits over the pedestal containing the Screw Attack, the smaller cylinder completely encasing the upgrade. However, if Samus activates four Luminoth laser turrets surrounding the vault chamber and aims them at sensors on top of the device, it will lift away from the pedestal and allow her to access the weapons system.
