Ninja Gaiden II: The Dark Sword of Chaos (NES)

A year after Ryu Hayabusa defeated the Evil Demon King and prevented the resurrection of the evil god in the previous work "Ninja Gaiden". The man who was controlling the Evil Demon King behind the scenes, the Fierce Demon Emperor Ashtar, starts moving on his own. In this game, you can climb up and down after being held on to a wall, or attack by consuming ninjutsu power while holding on to a wall, increasing your freedom of action. In addition, the "Alter Ego Technique" appears, in which up to two alter egos appear that follow Ryu and attack at the same time as Ryu. By successfully guiding the alter ego, Ryu's attack range will be greatly expanded.
