In Ninja Gaiden II, a new villain, Ashtar, is revealed. Take on the role of Ryu Hayabusa and rescue Irene Lew, a former CIA agent, from Ashtar. Destroy the Sword of Chaos, a weapon of great power forged from the bone of a demon. Use techniques such as the Fire Wheel or the Windmill Throwing Star and attack while holding on to walls and ladders. Utilize the most innovative technique of all--the ability to create Shadow Clones, orange shadow versions of Ryu that will constantly follow him, repeating previous actions (moving or attacking) in a delayed cycle. Once again defeat henchmen, creatures, and bosses with new fighting techniques and even more weapons as you progress through multiple stages on your way to destroying Ashtar, Jaquio, and the Realm of Chaos.
