Enter immobile with G-mode direct, with the Metroids having been killed previously. Take a Rinka hit to regain mobility. Back up to between 1 and 6 pixels from the door transition, and activate X-ray to get very deep stuck in the door. Climb up 1 screen, moving quickly to minimize Rinka damage. Perform a turnaround buffered spin-jump away from the door to trigger the transition, bypassing any lock on the door.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "direct",
    "morphed": false,
    "mobility": "immobile"
  }
}

Requires:

{
  "or": [
    "f_KilledMetroidRoom2",
    {
      "obstaclesCleared": [
        "f_KilledMetroidRoom2"
      ]
    }
  ]
}
{
  "enemyDamage": {
    "enemy": "Rinka",
    "type": "contact",
    "hits": 1
  }
}
"canXRayClimb"

Bypasses door shell: true

Dev note: The 'immobile' requirement in the entranceCondition is not necessary but is included for clarity. Without coming in immobile, it would not be possible to have enough energy to survive the Rinka hit. The enemyDamage in this strat is for a second Rinka hit while climbing. The first Rinka hit is included in the gModeImmobile requirement.
