Cannon Dancer

The controls of Osman consist of an eight-way joystick for moving the character, and three action buttons for attacking, jumping, and activating a special attack which will destroy all on-screen enemies (which has only a limited number of uses and cannot be fully replenished until the player loses a life). The player can also climb walls and ceilings as well. The player character attacks primarily with his powerful kicks, which can fatally slice through most of the enemy soldiers in the face. Pressing down and jump will cause to slide.

While sliding, the player character can do a slide kick with the attack button or grab certain enemies and flip them over with the jump button. The player can also dash by holding the joystick left or right after sliding.

Osman is set in a dystopian late-21st century in which Earth is under control of a single federal government. One day, a new threat known as "Abdullah the Slaver" – an evil sorceress who wants to take control of the world – appears, causing widespread terror and panic. This fear incites the abandonment of all economic activity and corruption in the government, which now undermines the foundations of society itself. Judicial Affairs Director, Jack Layzon, fears the worst and summons a lone assassin.

The player controls a Cannon Dancer called Osman (Kirin), a top-class agent in a mercenary unit known as "Teki", and a highly skilled martial arts fighter. As he travels toward the Federal Capital in Prague, he has to face not only Abdullah the Slaver and the government forces but also the other members of the Teki, who want him dead for personal reasons. Osman is hired by the Federal Attorney general Jack Layzon to reclaim one of his cities from a terrorist-leaning cult named Slaver, who worships a "God without form". Osman infiltrates the city in the midst of the night and makes his way into the cult's main temple at its center.
