These are the items that appeared in Phase 7.
Each of these Beams is in one of four rooms connected by a shaft in the middle of the ruins. Because the Beams cannot stack, Samus will have to reobtain whatever one she wants to use next.
Samus must enter the Zeta's chamber and jump up through the opening above to enter the next room. Here, she must bomb several blocks and roll underneath the wall to reach the Screw Attack.
Energy Tanks 1 and 2Edit
Both are in the highest parts of the Grand Cavern. The first is found at the top of the Chozo tower, in the shaft on the right, which is only accessible through the Dark Chamber. The second is in a tunnel in the ceiling, only reachable with the Spider Ball.
Missile Pod 1Edit
In a tunnel in the Grand Cavern ceiling, the same place as the second Energy Tank.
Missile Pod 2Edit
Samus must descend the left shaft into the top of the Chozo ruins and roll through the lowest tunnel of the Dark Chamber. This Pod is at the end.
Missile Pod 3Edit
Down at the bottom of the Grand Cavern, in a small tunnel on the left corner of a pool of water.
Missile Pod 4Edit
Halfway up the right side of the Grand Cavern, above the ledge leading to a Zeta Metroid's domain, Samus will find another ledge below the place where she fights a Gamma Metroid. This Pod is in a small pit.
