These are the items that appeared in Sector 5.
The Gravity Suit is regained upon the defeat of Nightmare.
Energy Tank 1Edit
The Energy Tank is in the door above several floating Rippers in the shaft near the Data Room. Samus enters the room by freezing a Ripper. The Energy Tank is in the wall to the left of the Fake Energy Tank.
Energy Tank 2Edit
Through the Gadora guarding Nightmare is a small chamber leading down to Nightmare. Laying a Bomb near the wall will reveal a tunnel that drops Samus down to the Tank, as going straight for it leads her to a trap.
Energy Tank 3Edit
Samus will come across an opening on the right of an underwater shaft during her search for the Nightmare. After killing it, she can return to this shaft and fire a Missile at the wall adjacent from the opening. Bombs must not be laid in the next chamber or else a Shutter will rise and block off the Tank.
Missile Tank 1Edit
The Missile Tank is in the room at the bottom right of the first shaft of the sector. It is located behind a Bomb Block in the upper right corner of the room.
Missile Tank 2Edit
The Missile Tank is in the room to the bottom left of the first shaft. It can be collected before Samus obtains the Ice Missiles, but once Samus collects them, Samus must wait until the emergency in Sector 3 is resolved for another chance to get it. It is in the center container, which has a pass-through block on the bottom-left. Samus can jump through it to reach the tank.
Missile Tank 3Edit
At the bottom of the shaft to the right of the Data Room is a Morph Ball tunnel leading to another shaft leading straight up. Samus must kill the Zeela in the room, causing it to become a Choot. Samus must then freeze the Choot while it is jumping to reach a higher ledge. Samus then kills another Zeela to create a Ripper. Samus must freeze the Ripper and use it as a platform to reach the tank in the ceiling.
Missile Tank 4Edit
Samus must reach the top left corner of the room that initially holds Nightmare. She can do this before or after Nightmare breaks loose. Prior to Nightmare's escape, Samus must freeze several Choots and use them as platforms. Afterwards, Samus can use the Space Jump. The Missile Tank is in view through the door to the left.
Power Bomb Tank 1Edit
The power bomb is in the room to the left of the SA-X encounter. It can be obtained using a Power Bomb to destroy the wall.
Power Bomb Tank 2Edit
In the upper part of the room with Power Bomb Tank 1 is a ceiling made of Power Bomb Blocks. This will lead to a shaft containing Rippers and a door on the right at the top. Samus must either freeze the Rippers to use them as platforms, or use the Space Jump to get to the door. Inside the door is the tank.
Power Bomb Tank 3Edit
In the room to the left of the cyan Geron in the large room is the tank. Samus must freeze the Rippers with Ice Missiles to avoid falling down into the crumbling blocks. At the end of the room is the tank.
Power Bomb Tank 4Edit
At the very top of the main chamber (following Nightmare's escape) and through the left door, Samus must clear out all Choots and then charge her Speed Booster. She must then Shinespark through the door. The Power Bomb Tank will be on a ledge.
Power Bomb Tank 5Edit
Again in the thawed main room of the Sector, through the wrecked door in the top right. Samus must shoot out the ceiling and then lay a Power Bomb to expose more ceiling. Above, she must shoot two Shutters, and the Tank is found in the platform.
Power Bomb Tank 6Edit
In the damaged room inhabited by two Geruboss, Samus must shoot open the ceiling and enter the left room. She must then use a Power Bomb to reveal the tank.
Power Bomb Tank 7Edit
The adjacent chamber features a tunnel that can be revealed with a Power Bomb. Samus can jump into another hidden tunnel toward the left side. The tank is to the left, hidden in a block.
Power Bomb Tank 8Edit
Returning to the corridor with Aqua Zebesians and Skultera, Samus must clear out all hostiles and Speed Boost through the door on the right. She must keep running and destroy two Boost Block walls, and then Shinespark through the ceiling between the walls.
