Mega Man Zero 3

This game follows almost exactly the same rules as its predecessor, Mega Man Zero 2. Once again, Zero has his Z-Saber, Buster, and Shield Boomerang. However, Zero's rod weapon (originally the Triple Rod in Mega Man Zero and the Chain Rod in Mega Man Zero 2) has been replaced with the Recoil Rod: a pair of tonfa-like weapons that can be aimed in all directions. When charged up, a powerful stabbing attack is performed, which can knock enemies back, or propel Zero into the air if aimed down to the ground, like a makeshift pogo stick.

The Cyber Elf system has been given an overhaul with the introduction of Satellite Cyber Elves. These are different from the standard Cyber Elves, which have been renamed "Fusion Elves", in that they are equipped for a constant benefit, and the use of them will not affect the mission ranking score. However, only two Satellite Elves can be equipped at once.

Two months following Zero's victory over Elpizo, the Dark Elf remains at large. During this time, Ciel has finished her research on a new energy supply to end the crisis, dubbed the "Ciel System". While en route to Neo Arcadia to propose the Ciel System in hopes of ending the conflict and the genocide of Reploids, a spaceship with the Dark Elf's energy reading crashes to Earth.

Zero sets out to investigate, but instead finds the remaining Guardians (Harpuia, Fefnir, and Leviathan) fighting against a gigantic Reploid named Omega and a scientist named Dr. Weil — both who were banished to space due to their crimes in instigating the Elf Wars and turning the Mother Elf into the Dark Elf a century prior. Dr. Weil reveals he has resurrected Copy X, who resumes his rule over Neo Arcadia, much to Harpuia's chagrin.

Mega Man Zero 3 was the fourth best-selling video game in Japan during its week of release. It was the 106th best-selling game in the country for 2004 at 121,847 units sold. The game would later become one of the cheapest game of the Mega Man Zero subseries to repurchase.

A common comment made by reviews of the game is that Mega Man Zero 3 is similar to its predecessors and has not changed much in terms of gameplay. Reviewers complain often about the difficulty level of this game's predecessors and were quick to praise the game's difficulty level for being more forgiving but still challenging.
