Snafu the Great
Nothing fancy. Ryu simply has to survive Contra, Super C and Contra 3: The Alien Wars.
The twist is that for the first 2 Contras, he is his NES version whereas Contra 3, he is his SNES version. All powerups from Ninja Gaiden 1 are in the first Contra, those in NG2 are in Super C and those in NG3 are in Contra 3.
