Riki, a skilled martial artist, embarks on a mission to liberate his girlfriend Kyoko from the clutches of his nemesis Wang across six horizontally scrolling stages filled with increasingly dangerous adversaries. Each level forces Riki to battle through waves of henchmen and occasional mid-stage challengers before confronting a powerful boss guard with a specific vulnerability that must be discovered and exploited. The combat draws inspiration from classic martial arts storytelling, featuring spectacular finishing moves that send defeated enemies flying apart in explosive fashion. Success hinges not merely on fighting prowess but on identifying each boss's weakness—some may only yield to strikes, others to kicks—and timing the appropriate counterattack to emerge victorious.
