After you obtain the Storm Missile ability in Ferenia, you return to Ghavoran.

Return to Burenia

Go through the door above the Total Recharge Station, and roll through the tunnel there, using bombs to get rid of the blocks in the way. At the end of the tunnel, fall into the water, then Space Jump to the right to reach the ledge on the right. Roll through the tunnel and you will see a Missile Tank on the right, but you will fall through Pitfall Blocks before you can get it. You will land in front of a Teleportal. Use it to go back to Burenia.

Get a Missile Tank

Go to the left, shoot the door, then open it and go through. Go to the left and land in the water, then go to the right and land on the ledge on the right side. Space Jump to the left and land on the ledge there, then Space Jump left and downward to reach the platform below that has (or had) a Missile+ Tank on it. Use the Grapple Beam from there to pull yourself to the blue wall above and to the left. This will reveal a door. Since you can't reach it from here, Space Jump to the right side of the room. If you end up below the ledge that leads to a door on the right, go up and roll through the tunnel below that door, then go to the right, then jump up onto the ledge above the tunnel that you came through, and go through the door on the left. Then, from the ledge with the door, Space Jump to the left to reach the door on the left that you revealed. Open it and go through.

You can use the Energy Recharge Station if you wish. Then go back toward the door on the right, and bomb the floor to the left of the door and fall into the tunnel that appears, then go to the right and use a bomb to break a hole below you. Roll to the left to get the Missile Tank.

Get an Energy Tank

Go left from the Missile Tank to fall below. Keep going downward, and a floating creature will appear to the left of the door at the bottom. Use a Melee Counter when you see the flash, then shoot the creature to kill it. Then go through the door on the right.

Go to the right, and when you begin floating downward, Space Jump to the left to reach a corridor on the left with a door at the end. Go through the door.

Make your way upward, then go through the door on the left if you wish to save the game, then leave the save room, and jump over the gap and go through the door on the right.

Go to the right and go down below, and shoot the red thing in the wall. Then stand on the right side of the ledge, and use the Grapple Beam on the Grapple Beam Block across from you. Pull it to destroy it, then wait for floating creatures to come out of it, shoot them, then Space Jump to the tunnel and roll through it. If the creatures knocked you down, Space Jump to the left and go through the door, then go upward and go through the door on the right, where you can try again.

From the tunnel where the Grapple Beam Block was, go downward and go through the door at the end. Kill the electric creature on the right, then charge up missiles and use the aiming laser to lock onto the green dots in the ceiling, to destroy the Storm Missile Box. Use the Grapple Beam on the top of the blue wall on the right, then Flash Shift to the left to reach the Energy Tank.

Get an Item Sphere

Then go to the right and make your way downward. Kill the creature there, then shoot the wall on the left if you didn't already break open a tunnel in it when you shot the electric creature, shoot the floating creatures that come out of the tunnel, then roll through the tunnel.

In the next room, drop down below, being careful to avoid the large creature in the area and the toxic area it creates beneath it, and go to the right until you reach the next room. Use Storm Missiles to kill the creatures here, then go to the right and roll through the tunnel at the end.

In the next room, shoot a charged shot at the red thing in the wall above you. When it has been destroyed, go back through the tunnel, then jump up into the tunnel above the one that you just came out of, be careful of the floating creatures, and go through the door at the end.

Go to the right until you reach the bottom of the area, then go up the ledges on the right, using Storm Missiles on the electric creature. From the ledge on the right, Space Jump to the left to reach the ledge there. Jump up and out of the water, then go to the right and go through the door there.

Kill or freeze the wall creature up above, then Space Jump upward and kill or freeze the ceiling creature. Use Phantom Cloak to go through the door at the top.

Go to the left and kill the floating creatures, then get in the water and go to the left edge of the platform. Kill the floating creatures that come toward you, then Space Jump to the left, to reach a ledge with a tunnel above it. Go up through the tunnel. Kill the floating creatures in the room at the top, then shoot the red thing in the wall. When another red thing appears, shoot it as well, then shoot a charged shot to hit the next red thing. Finally, use the Grapple Beam to pull the Grapple Beam Block across from you.

Roll through the tunnel on the right, and go to the bottom of the room. Then go up the ledges on the left, then go left and shoot a missile at the door, then open it and go through.

Go to the statue and shoot the item sphere, then jump onto the item to get the Gravity Suit. You will no longer move slowly in water, and you can safely enter lava, and areas of extreme cold. It increases your defense, and increases the damage inflicted by Dash Melee.

Return to Artaria

Go through the door on the right. Space Jump upward through the water until you are above water. There is a Missile+ Tank above, but you can't get it yet. Kill or ignore the creature coming out of the floor (Storm Missiles are helpful against it), then go through the door on the right. You will get a briefing and can save the game.

From the save room, go through the door on the right. You can't get the Missile Tank here yet, so just go to the right and get into the elevator to return to Artaria. There will be a cutscene.

Shoot a missile at the door on the right, then go through. If you Space Jump to the right, you can get a Missile Tank. Then go to the left and the platform will rotate. If you didn't get the Missile Tank to the right of the platform that rotated, you can Space Jump back upward to get it now. Then go to the left from where the Missile Tank was, and fall down below. Use the Total Recharge Station if you wish, then go to the right to land on the ice, and roll through the tunnel on the left. Kill or freeze the wall creature and Space Jump up and to the left, then go down the left side. Go to the right and slide through the tunnel, then go to the right and roll through the tunnel there. At the end, Space Jump up to the door at the upper right. Go through.

Shoot the door on the right and go through, then shoot a charged shot at the ceiling to destroy the red thing and rotate a platform. Jump up to the top, then go to the right and fall down the tunnel. You will fall through some Pitfall Blocks at the end and face off against another Chozo Soldier.

Chozo Soldier

This one has a shield. Use Storm Missiles on it. Otherwise, dodge its attacks like before. It may put its shield down and then flash, allowing you to do a Melee Counter. Eventually it will change form. This time, if it jumps onto the wall, be prepared to Space Jump because it will spit a large stream of black stuff at you for several moments. It can also jump downward onto the floor and create two black waves that you need to avoid touching. Continue using Storm Missiles and hitting it, and eventually the camera angle will change and it will reach back its spear. When it flashes, perform a Melee Counter, then when it flashes again, perform another Melee Counter to defeat it.

Get a Second Missile Tank

After the battle, you can optionally go through the door on the left and Space Jump to the top of the room to get a Missile Tank. Afterward, go back down to the bottom of the room and go through the door on the right to return to the room where you fought the Chozo Soldier.

Get an Energy Part

From the room where you fought the Chozo Soldier, go through the door on the right. Go downward and get the Energy Part. Then go to the left to drop down from the ledge where the Energy Part was, to reach the lower area of the room. Go to the right from there until you reach a door. Go through.

Get a Third Missile Tank

Go upward, then go to the right and go through the door there. Then keep going to the right to reach the next room. Go to the right, use the Energy Recharge Station if you wish, then go through the door on the right.

Go to the right side of the room, using Storm Missiles on the creatures along the way. Roll through the tunnel at the end. From the Ammo Recharge Station, jump up to the ledge on the right, shoot the missile block with a missile, slide through the gap, shoot the beam block, slide through the gap, then slide through the next gap and go through the door on the right. Step on the glowing panel on the floor to get a briefing and save your game.

Go through the door on the right, then go right and slide through the gap, then Space Jump to the top left of the room, where there is a Missile Tank. Take it, then use a bomb at the base of the wall beneath where it was, and roll through the tunnel. Space Jump upward from there and go through the door at the upper left.

Return to Cataris

Go upward past a wall creature and a flying creature, go through the door at the upper right of the room. Keep going to the right, and slide through the gap at the end, then go to the right and go upward. There is no need to use Phantom Cloak to get through this door; it's frozen, so just go through it.

Go to the left, then go upward when you can. Go through the door at the upper right of the area. Go to the right, then upward to the door at the upper right, and Speed Boost through. Shoot the door at the end and go through it.

In the next room, go down to the bottom, then go through the door on the right. In the next room, Space Jump to the upper right and go through the door there. In the next room, Space Jump upward to reach the elevator to Cataris.

Go Through the Area

Shoot through the walls on the left, then go to the leftmost side. Go downward through this room. You can optionally go through the door on the left to save. Leave the save room and go down to the bottom of the area. Shoot charged shots at the red thing in the wall (if there is one), then get the Missile Tank (if you didn't before), then roll through the tunnel there, and roll through the tunnel to the left of that to go to the next room.

You can use the Total Recharge Station if you wish. Then go upward, then to the left to find an eyeball monster on a door. Kill the monster, then go through the door, then go to the left and up to find a Morph Ball Launcher. Roll into it and drop a bomb to activate it. There will be a cutscene.

Experiment No. Z-57

When the enemy reaches an arm up to the upper corner of the room, Space Jump at the top middle of the room until it has finished swiping both arms across the bottom and sides of the area.

It will spit a pink beam at the floor. The pink goo on the floor will damage you if you step on it, but there will always be one place with no pink goo, so Space Jump (but be sure not to touch its arms) until you can land on the safe spot, while also avoiding the stream of pink goo that it is spitting out.

It will go to one side of the room and shoot a stream of pink goo in an arc from the top of the room to the bottom. Stand near its face to avoid getting hit by it, but be prepared to perform a Melee Counter when it flashes after it finishes spitting goo. If you do this successfully, shoot missiles or charged shots continuously until you are back in the room. Continue the battle as before.

Eventually, it will drop some ammo/health, then it will put its four hands on the walls/ceiling. Target them with Storm Missiles and destroy them before the enemy can shoot a beam at you.

When the boss goes to the right and appears to be charging up an attack, you will need to space jump over a series of beams that come from the right side of the room, while powerful fans are pushing you toward the toxic goo on the left wall. There will be gaps in the beams that you can Space Jump through. Afterward, the fans will get stronger, so Speed Boost to the right to avoid getting pushed into the wall of goo on the left. It is possible, but difficult, to ready a Shinespark at this time, then jump up, shoot at the boss so you are horizontally in line with it, then press B and Shinespark at the boss's head.

If it reaches both arms across its face, Space Jump to the upper middle of the room to avoid when it swipes both arms along the walls and floor, then quickly go to the left or right to avoid its head.

Eventually, there will be a cutscene where you shoot charged shots at it, and the battle ends.

Return to Artaria Again

Go to the right and drop down to the area below, then go to the right until you can go upward. Near the top of the area, go through the door just below the upper right door, then go to the right and downward to a Total Recharge Station. Then go upward and roll through the tunnel in the wall on the right. Go to the right through the next tunnel, then go upward. You can go through the door on the left to save, then from the save room, go through the door on the right, then continue going upward through this room. At the top, go to the right while shooting your beam. Ignore the elevator and go through the door on the right. Make your way upward, then go to the upper right and go through the door there.

Get in the lava and slide through the tunnels to reach the bottom. Then go to the right and Space Jump upward to the Teleportal above. Use it and it will take you to Artaria.
