Cap'n Magneto is a sci-fi graphical adventure game designed and developed by Al Evans. The player assumes the role of spaceship captain Lance Magneto, who has crash landed on a planet populated with aliens and robots. Some are friendly or neutral toward the player, while others are hostile and will attack on sight. The captain can only understand their language with the assistance of a tricorder device found near the crash site. Exploring the map reveals numerous objects to acquire: mundane items such as apples and oil cans; weapons and armor; and ultimately the Crown of Control, a mind-control device vital to escaping the planet.
