Master O-Dor and his army of Ranx have invaded and slain almost all of the Ninja clan sworn to defend the land against evil. All except one aged and frail master simply know as “Sensei,” and his angry, untrained rookie. In an effort to fight back, Sensei undertakes a secret mission to Robot Beach to seek the help of Yang, a legendary Ninja Guardian, who has one of the Rage Stones. Fight with an arsenal of classic ninja weaponry like shurikens, swords, and blowguns, as well as powerful modern day weapons, including rocket launchers and guided missiles. Perform numerous acrobatic feats such as wall-running, rail grinding, swinging from a chain hook and more. Use your weapons and skills to defeat the evil villain Master O-Dor and his menacing army in a quest that spans five extensive environments.
