Mega Man OP2

 (going to go by the title "Rockman OP2" for a possible Japanese translation) is an Mario Obsessed fan game based on the Mega Man series. It is the sequel to Mega Man OP.

Like it's predecessor, it got a mostly negative reception, though has been acknowledged to be an improvement. Another sequel is in the works.

Story
Taking place some time after Mega Man 11, a robot invasion occurs in Japan. During which, Mega Man is destroyed by an 'OP' version of Skull Man who tells Zero OP that someone named Dr.Izumi is taking over the place. Zero OP decides to fight alone.

Dr.Izumi tells Skull Man OP to kidnap a young girl named Momoko (who had apparently revived Mega Man into his OP form in the first game), as well as drop an 'OP Device' at her home. He does so and the device revives Mega Man OP in a new body. The newly-formed hero goes off to stop Dr.Izumi.

Reception
Nico, from The Retro Job, reviewed the game. On the Retro Job website it sits at 0.1 stars, with the review stating: "It’s a 0.1 step up from the original game...The game is criminally long for what it is." He praised it for a few levels, but criticised it for it's length, visual design and laughable bosses.

Trivia
