Be careful to avoid the stationary, invisible projectiles that the pirates spawn from where they jump. It is possible to exit G-mode and quicky pause abuse, to collect the pirates' drops and get to the door.

Requires:

"h_heatedGMode"
{
  "or": [
    {
      "ammo": {
        "type": "Super",
        "count": 6
      }
    },
    {
      "ammo": {
        "type": "Missile",
        "count": 36
      }
    }
  ]
}
{
  "or": [
    {
      "heatFrames": 45
    },
    "h_heatedGModePauseAbuse"
  ]
}

Clears obstacles: A

Dev note: It is possible to enter the room in direct G-mode, kill the pirates, return to the open door, then exit G-mode and quickly touch the transition to awaken Zebes (but not get the metal pirates kill flag). This is not included, as it is a very niche knowledge check, and at that point, you might as well pause abuse to get the pirate drops and both flags.
