It's a delayed walljump while the water is low, followed by a tight walljump off the bridge. This strat is easily bypassed by jumping through the door, or if the door can be opened.

Requires:

"canSuitlessMaridia"
"canInsaneWalljump"

Triple frame perfect dashing stationary spinjump into delayed CWJ and precise hitbox manipulation.

Requires:

{
  "notable": "Taco Tank"

"canCWJ"
"canInsaneWalljump"
"canStationarySpinJump"

Jump to the door leading to X-Ray either by jumping from spikes or with a very precise jump. Cross the room by Jumping atop the spikes. Taking enemy damage can be used to reduce some spike damage. The final jump can either be made by jumping from the bottommost spike stair or from the safe stair. Setup run speed atop the spike stair by holding forward to be pushed backward. The safe stair jump is much harder, but can be made without every pixel of runway.

Requires:

This is the same size of ledge as writg, so it should be equally possible.

Requires:

"canInsaneWalljump"

Use a very well timed and precise walljump into morph to hit the global Sova so that the damage bonks Samus up to the door ledge. Aim for the lowest part of slope looking wall tile, where it does not look possible to make contact with a walljump, and fully delay the jump. To try again, the Sova loops to the left side wall. Or a Super can knock it off the wall to climb the right side again.

Requires:

{
  "notable": "Sova Morph Only Boost"
}
"canInsaneWalljump"
"canMidAirMorph"

    "enemy": "Sova",
    "hits": 1,
    "type": "contact"
  }
}
{
  "heatFrames": 1050
}

Wait for the global Sova to begin climbing the wall below the door. Time a walljump into instant morph where Samus boosts off of the Sova with the right timing to bounce up to the door's ledge. The jump must be a fully delayed walljump. Normalizing the camera can help with timing the walljump. The damage boost can be attempted again when the Sova climbs down the left wall, or by knocking it off the wall with a Super Missile.

Requires:

{
  "notable": "Sova Boost"

Use a fully delayed walljump to gain enough horizontal distance to place a bomb past the lip of the overhang. Unmorph to hover in the air above the bomb while it explodes. Ride the explosion into a down-grab to reach the ledge.

Jump into the spike pit, hitting the Ripper to avoid spike damage. Climb the left wall while avoiding falling onto the spikes or through the crumble blocks. The ledge is the same size of that in writg.

  "notable": "HiJumpless Wall Jump"

BounceBall into the Lava, Unmorphing with good timing to sink faster and drift effeciently towards the bottom right Namihe. Walljump at about eye height (4 pixel window) to gain enough height to reach the center portion of ceiling. While rising, wiggle to shrink Samus' hitbox. Some walljump positions will not need to wiggle, when walljumping far away from the Namihe. Jumping, from the wall, around the next lowest overhang is very precise and taking any extra time to position will increase the amount of lava damage being taken. It may help to disable HiJump for this part. Then Walljump again to exit the Lava and reach the left ledge.

Requires:

  "notable": "GT Max Suitless Right Side Climb"

Run and jump at the very edge of the center platform. Wait for the water level to begin lowering to walljump on the far edge. An airball may be a little easier.

An extremely precise spinjump or walljump can avoid the top Boulder. The spinjump requires dash state and to jump right away. Aiming down shortly after helps by reducing Samus' hitbox.

Do a low spin jump and press against the right side of the door frame. Wall jump as low as possible, jumping as soon as possible after moving away from the wall. Immediately turn back to the right and try to press against the door frame again before the transition, while maintaining spin. After the transition, typically a momentum-conserving turnaround is needed to avoid bonking.

Entrance condition:

Align with the wall below the door while facing left. Hold dash, turn around, start running and arm pump once. Jump from the rightmost 'X' in the background. Release forward at some point while airborne, but repress it again before the CWJ. Immediately after the CWJ, shoot the Metroid to avoid getting grabbed.
