After navigating through the Metroid-infested corridors, you will reach the chamber of Mother Brain. She is protected by a series of Rinkas (flying rings) and a laser turret. First, you must destroy the Rinkas and the laser turret using your regular beam. Once these defenses are down, Mother Brain's glass casing will be exposed. Fire Missiles directly at Mother Brain's exposed brain. She will retaliate with powerful energy rings. Dodge these as best you can while continuously firing missiles. It takes a large number of missiles to defeat her. Once Mother Brain is destroyed, a self-destruct sequence will initiate, and you'll have a limited time to escape Zebes.
