Metroid Prime 3: Corruption/Bosses

Berserker Lord
The Berserker Lord is basically a more powerful version of the Berserker Knights. In battle you shoot the red orbs on the Berserker Lord's shoulders. After being shot enough, the orbs will shatter and the Berserker Lord will fire energy blasts at you. You must then shoot the blasts and they will return and hit the Berserker Lord. Repeat this until its head plate shatters. You can then shoot its head until it is defeated. You encounter two Berserker Lords throughout the course of the game; one on the G.F.S Olympus that battles you before you go to Norion, and the other in Elysia that is guarding the second bomb shard.
