On entry, kill or dodge the first Rinkas then Crystal Flash directly above or below a Rinka Spawner.

Entrance condition:

{
  "comeInWithRMode": {}
}

Requires:

{
  "or": [
    "f_KilledMetroidRoom2",
    {
      "obstaclesCleared": [
        "f_KilledMetroidRoom2"
      ]
    }
  ]
}
"canRModeCrystalFlashInterrupt"
{
  "ammo": {
    "type": "Missile",
    "count": 10
  }
}
{
  "ammo": {
    "type": "Super",
    "count": 10
  }
}

Dev note: There could be a variant with the Metroids alive, but they will all lure to Samus and the light orb will disappear, so she will take heavy damage. This is not possible in G-mode, because the Power Bomb will kill the Rinka and prevent more from spawning.
