Subchamber Two is a room in the Impact Crater. The room is accessed from the Subchamber One, and leads to Subchamber Three. Samus enters the room during the battle with the Metroid Prime. The room has a number of white structures on one side. There are three grooves in the ground which Samus can use to avoid the Metroid Prime when it charges by rolling into the Morph Ball. During the battle, the Metroid Prime will destroy the white structures, revealing Energy and Ammo. Once the Metroid Prime has taken 50% damage, it will retreat into Subchamber Three, and Samus will follow.
