The young general Yamanouchi Kagetora, intent on avenging his father's death, has revived the most ingenious weapon ever to hit the medieval battlefield: the Odama, a gigantic ball powerful enough to destroy whatever it strikes, friend or foe. Players use the Nintendo GameCube Mic to direct their soldiers out of the Odama's way and into the fray, and prove that they have the skill to back up the power of the Odama. 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 Mic, players command men to charge the enemy, defend positions, seize the enemy gates and much more.
