Robowarrior takes place on an alien planet named Altile. Players pilot a cyborg named ZED (an acronym for Z-type Earth Defence) as he raids Altile to fight the Xantho empire and destroy its leader, Xur. ZED uses bombs to hurt enemies, destroy his surroundings, and uncover various hidden items. To progress from one period (level) to the next, he must find a number of keys to open a locked door.
