These are the items that appeared in Phase 4.
At the summit of the massive cliff in the area, Samus must drop down the other side of it into the water, and then proceed up to the Space Jump in the next chamber.
Past the Save Station inside the cliff, Samus must drop down to the very bottom of the nearby shaft and proceed through the left corridor. She will find the Spazer Laser Beam's chamber being blocked by a Red Hatch.
Near the bottom of the area, Samus will come to a corridor leading left. This will lead her to a Gamma Metroid, which she must kill to proceed. The Plasma Beam, like the Spazer, is blocked by a Red Hatch.
Energy Tank 1Edit
Samus must ascend the cliff until she reaches the second tunnel from the top. Through here is the Tank.
Energy Tank 2Edit
At the bottom of the area, Samus must proceed left and kill the Alpha Metroid she comes across. Continuing forward, down a staircase and past pillars, she will find the Tank in a corner of the room through a small gap.
Missile Pod 1Edit
At the bottom of the area, in a square midair structure. Samus must shoot part of it to get to the Pod.
Missile Pods 2, 3 and 4Edit
The final three Pods in the area are within the massive cliff. The first is reached through a shaft in the ceiling off the cliff - this leads to an area full of destructible dirt which Samus must navigate to reach the Pod. The second Pod is found in the first tunnel from the bottom of the shaft beside the cliff. The final Pod is reached by climbing the large area where the Gamma Metroid below the cliff is fought, and penetrating the ceiling.
