Jump into the first Samus Eater in the ceiling of Hellway. After teleporting and passing through the transition, X-Ray climb to reach the ledge above. Samus will be off-camera, but the slopes at the top will push the camera up, indicating when the climb is done.

Entrance condition:

{
  "comeInWithSamusEaterTeleport": {
    "floorPositions": [],
    "ceilingPositions": [
      [
        10,
        3
      ]
    ]
  }
}

Requires:

"canXRayClimb"

Dev note: Other ceiling Samus Eaters can also probably work. Floor Samus Eaters (e.g. in Alpha Power Bomb Room) won't work because it's not possible to climb above the Morph tunnel, which extends along the entire screen behind the transition.
