Two highly skilled ninja heroes enter a dangerous tower to defeat an evil force and return power to the local people. Armed with throwing stars and your ninja training, you'll face hordes of enemies in level after heart-pounding level as you make your way up the tower. In order to advance, you'll have to vanquish the boss at the end of each level, and do it before you reach the time limit. Play alone or fight side-by-side with a friend. Make use of hidden power-ups, health blocks, and more powerful weapons you find along the way in this tower; even a ninja needs all the help he can get.
