Ghosts'n Goblins is a platform game where the player controls a knight, named Sir Arthur, who must defeat zombies, ogres, demons, cyclopes, dragons and other monsters in order to rescue Princess Prin Prin.
The game is set four years after Arthur rescued Princess Guinevere (Prin Prin) from the demon Loki (Lucifer). They are engaged, and are about to get married. While spending a quiet moment Guinevere is suddenly kidnapped by a Red Guard.
It's a side-scrolling platformer that has the boys in gray running through houses, apartments, a burning house and a high-rise for starters as they battle a myriad of ghosts with their proton blasters.
