Completing Area 5

Walkthrough: Use the elevator on the right side of the main room, and once you step out, go through the door on your right. You should come to the next patch of poisonous flora, so use your Screw Attack to avoid them and break through the weaker walls. There will be a Missile Expansion at the top of this room, as well as a Zeta Metroid in the last room you come to. After defeating it, return to the room with the elevator. Go through the door to your right to get both the Missile Expansion and Super Missile Expansion. Otherwise, drop below and head toward the elevator in the lower left section of Area 5.

Don't use the elevator just yet, as you must first defeat the Metroid that is near. Head above the Save Station and follow the path to your left. Use your Screw Attack to make it through the red crystals and ensuing flora. The first room you find has a Missile Expansion inside. Use your Grapple Beam to make it to the next room, repeating the process to enter the lava room in order to face yet another Gamma Metroid. After defeating it, head back to take the elevator, leading to a new section of Area 5. Enter the room with the Plasma Beam, and then activate the Teleportation Statue. From there, go lower to find a path that will lead to the left.

Use your Screw Attack as you head down the path, eventually coming to the next Gamma Metroid. Defeat it, then head back to the room with the Teleportation Statue you just saw. Drop down to the bottom of this room, going straight into the water. Follow this next path up to the ceiling that you can destroy with your Screw Attack. Use your Grapple Beam to remove the block in your way, and then use this passageway to return to the Chozo Seal. On your way to it, you'll find another Missile Expansion.

Drain the purple lava once you reach the Chozo Seal, and then drop down. You should find a red orb once you do, one that can be destroyed with your Grapple Beam. Go down the path to find another Energy Recharge and Super Missile Expansion. In order to reach the next elevator, head to the far bottom right corner. Shoot a Super Missile diagonally through the hallway marked by two red spikes. This should hit a weak point that should all ow you to remove the red orb you find. Destroy it, and then head into the elevator to Area 6.

Missile Expansion #1: Directly before fighting the Zeta Metroid, shoot a missile between the two red crystals. Quickly use your Phase Drift after you do, getting past the crystals and through a hole to the Missile Expansion.

Missile Expansion #2: Return to the maze with the two-sided red orb. Grapple Beam it to the right, and then use your Screw Attack against the blocks. From there, use your Spider Ball up the first platform, and then Phase Drift to get across the weaker floor. Bomb the right wall to gain access to the Expansion.

Missile Expansion #3: On your way to the Metroid on the left side, Space Jump over the flora. Bomb the weak spot on the ground, and roll right over to the Expansion.

Missile Expansion #4: On your way out of Area 5, return to the room just before the place your fought and defeat the first Alpha Metroid of Area 5. Go to the bottom right corner, and then jump to grab the ledge. Roll over to find the Expansion.

Super Missile Expansion #1: Above the elevator is an area where you'll need to jump through a hole in the top right corner. From there, use the Spider Ball to reach a new door. Use your Phase Drift to run across the breakable floor, but continue it as you enter the next room. The Super Missile Expansion should be in front of the door that has a yellow barrier.

Super Missile Expansion #2: After draining the purple lava, drop below and destroy the red orb. Use your Spider Ball and activate your Phase Drift, dropping down onto the weak platform. Quickly use your Screw Attack to break through the ceiling and reach the last Expansion.

Aeion Tank: At the bottom of Area 5 is an area filled with water. Use your Screw Attack to break through a piece of the ceiling to find the Aeion Tank.
