Fall into the first Samus Eater in Hellway or Alpha Power Bomb Room. After teleporting and passing through the transition, X-Ray climb 2 screens to reach the space behind the bomb blocks at the top of the room. 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": [
      [
        1,
        13
      ],
      [
        2,
        13
      ]
    ],
    "ceilingPositions": []
  }
}

Requires:

"canLongXRayClimb"

Dev note: FIXME: In Hellway, a ceiling Samus Eater could probably also work, and shorten the X-Ray climb.
