G-Mode Morph Power Bomb Metroid Kill (Expert+)
Metroid Room 4
From: 1
Top Left Door
To: 1
Top Left Door

Kill the Metroids while artificially morphed without any movement items. With just 5 Power Bombs, place one on the first platform to kill some Rinkas and to lure a second Metroid. Place a second in the same region, then drop down and quickly place a third on the second platform and fall to the third platform while the first two Metroids die. The remaining two Power Bombs can safely placed here to kill the final Metroid. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed.

Entrance condition:

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

Requires:

  }
}

Dev note: FIXME: It may be possible to kill the Metroids starting at the bottom door. It is possible, but quite difficult to do this with 4 Power Bombs.
R-Mode Crystal Flash Interrupt (Expert+)
Metroid Room 4
From: 1
Top Left Door
To: 1
Top Left Door

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

Entrance condition:

{
  "comeInWithRMode": {}
}

Requires:

"canRModeCrystalFlashInterrupt"
{
  "ammo": {
    "type": "Missile",
    "count": 10
  }
}
{
  "ammo": {
    "type": "Super",
    "count": 10
  }
}

Dev note: Note that this and the top of Metroid Room 2 are the only of the Metroid rooms that currently allows the Metroids to be alive, as they can get stuck on the ledge. This is not possible in G-mode, because the Power Bomb will kill the Rinka and prevent more from spawning.
R-Mode Crystal Flash Light Orb Metroid Kill (Extreme)
Metroid Room 4
From: 1
Top Left Door
To: 1

On entry, kill or dodge the first Rinkas then Crystal Flash. While in the light orb, Samus will be almost immune and the Metroids will take damage. Lure the Metroids after Crystal Flashing, and return to the light orb to kill them.

Entrance condition:

Direct G-Mode Morph Crystal Flash Light Orb Metroid Kill (Extreme)
Metroid Room 4
From: 1
Top Left Door
To: 1
Top Left Door

On entry, Crystal Flash, then lure the Metroids to the light orb. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed. To do this, trigger Reserves on a Rinka below, or first damage down with some of the Metroids before killing them. To minimize damage taken, lure a Rinka away from its spawner before touching it to prevent multiple hits during the auto Reserve trigger.

Entrance condition:

{

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

Top Metroid Avoid (Expert)
Metroid Room 4
From: 1
Top Left Door

Avoid all of the Rinkas and Metroids with no equipment and taking no damage. One way to do this is to bait the top Rinkas to fire upwards, and then carefully spinjump around each corner as the Metroid below passes by.

Tank the Damage (Basic)
Metroid Room 4

Taking a rinka hit stops the Metroid damage for a while and is less damage. Note that angle-down shots with a Metroid on Samus are unreliable, so it is recommended to jump and shoot down to open the door.

Requires:

Exit condition:

Come in Shinecharging, Leave With Temporary Blue (Insane)

Metroid Room 4
From: 2
Bottom Door
To: 2
Bottom Door

If alive, the Metroids do up to 78 damage before the Rinka hits. Entering through the middle of the door will require less damage.

Requires:

{
  "enemyDamage": {
    "enemy": "Rinka",
    "type": "contact",
    "hits": 1
  }
}
{
  "or": [
    {

R-Mode Crystal Flash Interrupt (Expert+)
Metroid Room 4
From: 2
Bottom Door
To: 2
Bottom Door

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

Entrance condition:

{
  "comeInWithRMode": {},
  "comesThroughToilet": "no"
}

Requires:

{
  "or": [
    "f_KilledMetroidRoom4",
    {
      "obstaclesCleared": [
        "f_KilledMetroidRoom4"
      ]

    "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.
