Boss 7: RB176 Ferrocrusher

Learn how to defeat the RB176 Ferrocrusher boss in Metroid: Other M. This guide covers its attacks, weaknesses, and the strategy to win.

Alright, let's take down this big guy, the RB176 Ferrocrusher. It looks tough, but once you know its moves, it's pretty manageable.

Stats / Weaknesses:

• Arms: Freeze with Charge Shot, then destroy with Missiles.
• Back: Vulnerable after arms are destroyed, especially when close.

Phases:

1. Phase 1: Arm Attacks
   The Ferrocrusher will use laser attacks that don't hurt you, but the ground it hits will explode. Dodge vertical attacks by Sense Moving left or right, and horizontal attacks by Sense Moving up or down. Focus on its arms first. Charge shot them until they freeze, then hit them with missiles to destroy them. Keep using Sense Move to avoid its melee attacks.
2. Phase 2: Back Attacks
   Once its arms are gone, the Ferrocrusher will charge at you more often. Now's your chance to hit its back. If you're close to it when its arms are gone, Sense Move becomes spammable. Use this to get in more charge shots on its back, but be careful not to get run over.
3. Phase 3: Overblast Finish
   When it freezes to the ground, jump onto its back to initiate an Overblast. This will end the fight!

Strategy:

• Pay close attention to the ground – that's where the real danger is from its attacks.
• Sense Moving is your best friend for dodging both its ranged ground attacks and its melee lunges.
• Don't forget to switch to missiles after freezing its arms with Charge Shots.
• Once the arms are gone, get aggressive! Spamming Sense Move will let you get in close for consistent damage on its back.
• Watch for the tell-tale freeze animation to set up the final Overblast.
