Robo Warrior is an action-puzzle game released in 1988 for the Nintendo Entertainment System. It takes place on an alien planet named Altile. We follow the adventures of the cyborg ZED ("Z-type Earth Defense") as he attempts to defend the planet against the evil Xantho Empire. He must collect many items and weapons hidden on Altile to fight the Xantho Empire and destroy its leader, Xur. Only by using his bombs to clear a path deeper into Altile, collecting items, and killing enemies can ZED save the world.
