Shinespark multiple times up the shaft and overload PLMs with the camera scroll blocks which are against the crumble blocks. To overload PLMs in as few as 3 Shinesparks, spark diagonally in the shaft and hold backwards when hitting the top, then spark again to get up. Afterwards, exit G-mode by using another Power Bomb to enable X-Ray again, or use the bugs to trigger Reserves.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "direct",
    "morphed": true
  }
}

Requires:

    "openEnd": 1
  }

"canShinechargeMovement"

        }
      ]
    }
  ]
}

Dev note: Depending on the number of tanks, the Reserve trigger may or may not take very long. This is a worst-case scenario. Samus is not able to Crystal Flash twice in this room in Direct G-mode.
