Mega Man ZX: The Prequel, Light & Dark

Mega Man ZX Prequel is a fan game, created by the Chinese group Rockman Lab, set between the events of the Mega Man Zero and Mega Man ZX series. Unlike the ZX series, there are only two playable Biometals. Like Mega Man X4, players can choose between two characters, Nett and Elf. Nett uses Model X, while Elf uses Model Z. Both players can obtain EX skills after defeating bosses. Nett can change the property of his second charge shot while Elf can use special commands to perform various techniques.
