Introduces Splash Woman. The first Female Robot Master
Heavily influenced by Mega Man 2, using similar controls, music, and a lot of the same enemies.
During Magma Man's stage, if you stand very close to the lasers that fall from the ceiling (without dying), you can see sparks coming off of Mega Man's suit.
Added: Optional DLC. This DLC included a Endless mode where you go as far as you can before you run out of HP, a "Fakeman" stage in Time Trials mode, harder difficulty settings and even the ability to play as Protoman.
