Fun Fact: The winners of the Robot Masters design contest for Mega Man 4 were awarded “golden cartridge” editions of the game. Only eight of these cartridges were made.

The fourth game in the popular Mega Man platformer series introduced more story into the mix, but the mechanics were mostly the same. A new “Mega Buster” version of Mega Man's arm cannon premiered in Mega Man 4, and a new character named “Flip Top” Eddie would appear at predetermined positions within levels to give Mega Man random items like health or ammo.

Some critics took issue with what they felt was a silly story, and held Mega Man 4 up as a clearly lesser title in the series, if not the turning point in its quality overall.
