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 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. (wikipedia.org)
