The player takes the role of the knight Arthur, who must once again rescue the Princess from the demons. The antagonist this time is the Emperor Sardius (known as Samael in the Japanese version), who has kidnapped the Princess in order to obtain the whereabouts of the Goddess' Bracelet, the only weapon capable of destroying Sardius.[1] The game is a traditional 2D side-scrolling platformer, as with the first two arcade installments, in which Arthur must run, jump, and shoot his way through huge swarms of enemies and traps, before rescuing the princess.
