G-Mode Setup - Get Hit By Gamet (Expert)
Cosine Room
From: 1
Left Door
To: 1
Left Door

Lure the Gamets while preventing them from going off camera. Spawn them when the acid is high and rising to avoid running through it.

Requires:

"Morph"

Exit condition:

{
  "leaveWithGModeSetup": {}
}
Gain Flash Suit (Spikesuit) (Ignored)

Dev note: Leniency is not included, because a farm is available.
Metaree Farm (Basic)
Cosine Room
From: 1

Requires:

}
"ScrewAttack"
{
  "cycleFrames": 255
}

Farm cycle drops: 2 Metaree
G-Mode Morph Remote Acquire (Extreme)
Cosine Room
From: 1
Left Door
To: 1
Left Door

Wait for the acid to lower then quickly roll part way forward to trigger the Metarees and return. Then go again without any difficulty. Killing any of the Gamets will prevent them from respawning. With Bombs, horizontally boost then IBJ above the acid while waiting for it. It is possible with Spring Ball alone, but it is easy to take damage; perform small jumps but hold jump before landing to prevent a small bounce in which Samus can't jump. On the return route, jump over the Gamets to let them pass instead of racing to get them off screen.

Entrance condition:

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

Requires:

G-Mode Morph Remote Acquire, Power Bomb Boosts (Insane)
Cosine Room
From: 1
Left Door
To: 1
Left Door

Wait for the acid to lower then quickly roll part way forward to trigger the Metarees and return. Then go again without any difficulty. With Power Bombs alone is particularly challenging. Use a Power Bomb to kill the Gamets to prevent them from respawning. Place a bomb at the edge of the runway then hold forward with precise timing to get a boost to skip the first and land on the next safe platform. As quickly as possible place another and let it boost horizontally to the next platform, then another to get to the item.

With high movement precision, it is recommended to start a bit away from the edge (fully on the runway), giving a 3-frame window, or to start on the last pixel of the runway, giving a 4 frame window plus an extra non-consecutive frame. With slightly less precision, it may be worth starting as close to the edge as possible without falling off, as there are typically 4 non-consecutive frames that work (consisting of approximately alternating frames in a 6-frame window). Rolling into the bomb with momentum is not recommended and gives only a 2-frame window.

Entrance condition:

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

Requires:

"canTrickyGMode"
"h_artificialMorphBombHorizontally"
{
  "ammo": {
    "type": "PowerBomb",
    "count": 6
  }
}

Collects items: 2

Dev note: The requirements here are to get the item and return, as the item cannot be used during the return. It appears that there is virtually no risk in overloading PLMs - the left runway isn't close enough, and even placing two on each pillar will not overload PLMs. FIXME: Getting extra horizontal distance from the bomb needs a tech.
