Shoot a Super as a Sciser crawls near the top door, then freeze it mid-air and use it to clip up past the door shell. If you don't have Morph and X-Ray, you must shoot the Super while the Sciser is on the slope near the door, not on the door itself.

Requires:

{
  "ammo": {
    "type": "Super",
    "count": 1
  }
}
"canTrickyUseFrozenEnemies"
"h_canNonTrivialCeilingClip"

Bypasses door shell: true
