Mega Man Zero 3/Walkthrough

Suggested order

There are three selection screens where you have to choose a mission.

Selection screen 1:

1. Hellbat Schilt: he should be weak against Childre Inarabitta's EX-Skill, but he's almost always out of its range.
2. Blazing Flizard: he's weak against Hellbat Schilt's EX-Skill.
3. Childre Inarabitta: his stage requires high speed and practice with controls, therefore let's leave it quite late.
4. Deathtanz Mantisk: he has no elemental weakness, therefore he puts up the hardest boss fight.

Selection screen 2:

1. Blizzack Staggroff R: his stage conceals a Cyber-Elf that helps earning E-Crystals, great to level-up any other Cyber-Elf!
2. Anubis Necromancess V: he's weak against Ice weapons, but he's out of range for Childre Inarabitta's EX-Skill.
3. Hanumachine R: he's weak against Thunder weapons, but Hellbat Schilt's EX-Skill is more effective here.

Selection screen 2:

1. Volteel Biblio: it's finally time to use Childre Inarabitta's EX-Skill against a boss!
2. Cubit Foxtar: weak against Thunder weapons (especially buster and shield EX-skills).
3. Glacier Le Cactank: weak against Fire weapons (saber, buster, rod).
4. Tretesta Kerberian: a boss with no elemental weakness, plus his HP is 50% higher than any other boss in the game.

Replay the game

There are 9 unlockables. In order to activate them all, it is necessary to beat the game at least 7 times.

In "Hard Mode" Zero cannot use Cyber Elves, nor EX-Skills, nor the Cyberspace (except in the 15th stage), nor elemental chips, and only part of the weapons can be charged up.

In "Ultimate Mode" all Cyber-Elves are always active, but they don't affect the final score of the stages. The mini-games can be unlocked in Ultimate Mode.
