Play as the ninja Moonlight and engage in a fierce battle to avenge his father's death and unlock the secrets of his birth. Select between the original Arcade Mode and PC-Engine MODE, which includes a life gauge. Use four types of weapons: katana, shuriken, bombs and chain and sickles to battle your way through the enemies. Pick up power-up items and switch between weapons to give you the advantage. You'll need to consider the enemy attacks and your weapon's abilities in order to deftly make it through all seven stages. Use your skills and attacks to get through the game's boundless enemies and traps. That's what ninja action is all about.
