Oama (大玉, Ōdama?) is a video game for the Nintendo GameCube that blends tactical wargaming with pinball gameplay, created by Japanese developer Yoot Saito. Odama is placed in a feudal Japan setting. The main character is a young general named Yamanouchi Kagetora. Yamanouchi Kagetora is intent on avenging his father's death by reviving the most ingenious weapon ever to hit the medieval battlefield: the Odama. The Odama is a gigantic ball powerful enough to destroy whatever it strikes, friend or foe. Using giant flippers, players aim the giant Odama ball to bowl over enemies, shatter their defenses and wreak havoc on the battlefield. With the Nintendo GameCube Microphone, players direct their soldiers out of the Odama's way and into the fray by charging the enemy, defending positions, seizing the enemy gates.
