This room has two levels, which are connected by a lift in the middle and an opening to the east of the room. The lift is offline when Samus first visits here, but can be reactivated after she has acquired the Grapple Voltage by powering a terminal on the higher floor. Connected to both floors is an extra cylindrical part of the room which contains a large energy silo. The main energy device is entwined by Phazon vines, and the walls of the room show clear signs of Phazon infestation. The device also makes siphoning noises frequently.
Samus can enter the cylindrical part of the room by a small tunnel at an apparent dead-end on the lower floor. She can enter this tunnel in Morph Ball mode. This entrance is situated next to another tunnel which leads left. However, this tunnel is blocked by a small hindged panel. This panel can be moved by the Grapple Lasso to cover the right tunnel instead; it can not be removed and only one tunnel can be used at a time.
