Upon entry into the room, Samus must battle four Pirate Troopers, two of which become possessed by black fog. After their deaths, a Bomb Slot activates. When Samus uses this Slot, the conveyor system begins to work again. Samus must roll into the tunnel next to the Slot, which contains a lift that allows her to access the upper section of the Portal Terminal. She will run into a Talloric Alloy block; using a bomb on it will lower the first platform and lens in the room. Samus can jump over to the other side of the room and repeat the first step, to bring down another platform.

After bombing a third Talloric Alloy block, the last platform and lens moves down. Sunlight
