Subchamber Three

Subchamber Three is a room in the Impact Crater. The room is accessed from the Subchamber Two, and leads to Subchamber Four. Samus enters the room during the battle with the Metroid Prime. There are a number of orange roots high on the walls that serve no purpose. 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. Once the Metroid Prime has taken 75% damage, it will retreat into Subchamber Four, and Samus will follow.
