Ninja Gaiden II: The Dark Sword of Chaos features a new bad guy, Ashtar. Take on the role of Ryu Hayabusa again and deliver Irene Lew, a past CIA agent, from Ashtar. Destroy the Sword of Chaos, an arm of outstanding powerfulness forged from the bone of a demon. Use techniques such as the Fire Wheel or the Windmill Throwing Star and onslaught while holding on to walls and ladders. Use the most advanced proficiency of all - the power to make Shadow Clones, chromatic darkness variants of Ryu that will perpetually follow him, repeating old actions (moving or attacking) in an abeyant cycle. Once again get the better of henchmen, animals and bosses with new combating techniques and even more arms as you advance along multiple phases on your way to destructing Ashtar, Jaquio and the Realm of Chaos.
