Dev note: canWallJumpInstantMorph is not needed here, as the precision is very low.

Use both Geemers to climb the tall shaft by repeatedly freezing them. Note that one moves locally when on camera and the other moves globally. Once Samus is close to the top Bomb Block, freeze one Geemer low and jump as high as possible before placing a power bomb. Continue climbing with the Geemer that survives.

Dev note: Technically Samus isn't moving off-camera but is close to the edge; 'canOffScreenMovement' is for the difficulty of timing the unmorph, given limited visibility of the end of the passage and the Sova. If a Power Bomb is available, then lag from the explosion can make the movement much easier.

Avoid the bottom pirates and jump high enough to break the bomb blocks with a power bomb. During the explosion, climb the right wall passing through any pirates and use a movement item to reach the top.

Jump morph from the center platform to place the first Power Bomb Place two more on the platform itself to kill the bottom pirates Use a fourth to break the bomb blocks while also killing the last pirate.

Dev note: It's not really possible to hit all enemies with double-PB hits while not taking damage. Using Power Bomb Periphery is based on a strat that allows killing them and taking out the blocks with 4 PBs. This calculation ends up taking 5, leaving a spare PB. The movement item used does not increase heat frames except for IBJ in which case the PB can be used while IBJing.

Dev note: This doesn't require breaking the bomb blocks on the premise that you can't get here without breaking them.

Crystal flash to force a standup then spin jump up then morph to bypass the dead robot. Use Coverns to damage down if necessary. Note that if the Covern spawns on Samus while crystal flashing, it will deal large amounts of damage. To avoid this, it is recommended to kill the Covern and leave its drop, then quickly get in the morph tunnel and CF.

Dev note: If Phantoon is alive, 'Base' can be used instead. Note that this strat is useless in vanilla, as the item only spawns if Phantoon has been killed.

In R-Mode, kill the Coverns until there is Energy in Samus's Reserves. Get into the Morph tunnel and go to the far left. Wait for Coverns to damage Samus down until Reserves trigger, forcing a stand up and enabling her to escape. Note that it is required to break the bomb block above the Morph tunnel as well, in order to clip out.
