Mega Man Zero 3/Walkthrough

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

Selection screen 1:
 * 1) Blazing Flizard: he's weak against Hellbat Schilt's EX-Skill.
 * 2) Deathtanz Mantisk: he has no elemental weakness, but the stage is easier if you have the Flame Chip obtained from Blazing Flizard.
 * 3) Childre Inarabitta: his stage requires high speed and good practice with controls, therefore let's leave it quite late.
 * 4) Hellbat Schilt: he is weak against the Ice Chip, although he's almost always out of range for Childre Inarabitta's EX-Skill.

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, and Hellbat Schilt's EX-Skill is more effective here.

Selection screen 2:
 * 1) Cubit Foxtar: the very useful Double-Jump Foot Chip is obtained from her; weak against Thunder weapons (especially shield).
 * 2) Glacier Le Cactank: weak against Fire weapons (saber, buster, rod).
 * 3) Volteel Biblio: weak against Ice weapons (shield, saber).
 * 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.

In the summary table, unlock requirements are sorted by increasing difficulty.
