The opponents in your battle for supremacy are four types of Evil Ninja star-throwing Assassins whose skills are many and dangerous! Also out to spoil your day are Acrobatic Women Warriors and vicious Guard Dogs. At the end of each level you must overcome the Ninja Master in order to progress. Some examples of these superhuman villains are: A fire-breathing Fat Man, an Armor Clad Giant and the Green and Gruesome Giant Ninja - who has a disconcerting habit of suddenly multiplying into an army!
