The Bitter Well is a Phazon-filled room found in the Dark Agon Wastes. The majority of the room is taken up by a Morph Ball tunnel, while the rest is made up of two small areas where Samus can stand. In the middle of the room, there is a Light Crystal that illuminates most of the Bitter Well.
Samus must use Morph Ball Bombs in order to cross the Phazon to avoid losing large amounts of energy from falling.
