Freeze an Atomic or Covern at a precise distance below the door in order to jump up and clip through the door shell. If Phantoon is defeated, it is possible to lure the Atomic from below the shot blocks by placing a Power Bomb. Freezing it while it is moving horizontally and Samus is standing works as a trivial setup. If Phantoon is not defeated, stand on the stairs so that Samus is just a few pixels lower, then freeze the Covern low in its cycle. Alternatively, freeze it high then perform a tight down grab to get onto it for a pixel perfect clip.

Dev note: This is only for indirect G-Mode, because it is trivial while in direct, and would use a different strat. FIXME: If Phantoon is not defeated, this does not require Morph or artificial morph.
