Move very quickly to bring a shinespark from the speedway up to the Save Room door. Preclear the Cacatacs, and it may help to not run while platforming if HiJump is not available.

Requires:

"h_heatProof",
{"obstaclesCleared": ["A"]},
"canShinechargeMovementTricky",
"h_shinechargeMaxRunway",
{"shinespark": {"frames": 12, "excessFrames": 0}}

Exit condition:

"leaveWithSpark": {}

Unlocks doors:

{"types": ["ammo"], "requires": []}

Dev note: FIXME: This could be done without heat proof. FIXME: This should be changed to start at node 9.
