Kamen Rider is a traditional side-scrolling beat 'em up set in the sci-fi universe of the same name.
There are two protagonists to play as: Takeshi Hongo (or Kamen Rider 1) for player 1 and Hayato Ichimonji (or Kamen Rider 2) for player 2. They are fighting against an evil organization called Shocker that turned them into the mutant cyborgs, but failed to complete the brainwashing process. With help of their supernatural powers they have to finish 6 stages and get to the final boss.
