Ferenia

Pick up Energy Tank #5 in the small narrow morph ball corridor on the bottom left of the screen.

Acquire Missile Tank #31 near some beam blocks on the upper top side in a corner, just before the Escue boss battle.

Defeat Escue Boss #4. A recommended tactic is to Shinespark Escue at the start of the battle by building boost as you run through the boss door, pressing Down on the (L) stick to charge, staying to the left of the arena, and then smashing up into Escue's body while in Shinespark mode. Escue has low HP and one phase, using attacks like Electric Charge, Pulse Ball, and Missile Torrent. Dodge attacks with Flash Shift or well-timed jumps. Use Ice Missiles when openings appear.

After defeating Escue, you will receive the Storm Missile from the X-parasite. Look for the Storm Missile Box near the Item Sphere on the world map in Ferenia, towards the Ghavoran Shuttle on the left side of the map.

Before reaching the Storm Missile Box, defeat 2 Robot Chozo Soldiers (one gold, one silver).

Use the Storm Missiles by holding down the (R) Shoulder Button to blast all 5 switches inside to find the Space Jump from a Chozo Statue.

Travel to Ghavoran via the Shuttle, head left past the Total Recharge Station, go through the morph ball corridor, use the Space Jump in the water to cross a gap, and fall below to the Green Teleporter.

Take the teleporter to Burenia.

In Burenia, head deep into the area. Pick up Energy Tank #6 using Storm Missiles before a deeper plunge.

Utilize your Space Jump underwater and blast away at pink tentacles to bring down a large structure into the ground.

Head west of the map to find another Item Sphere where the Chozo Statue holds the Gravity Suit.
