Videocart-23 combines two futuristic games on one cartridge: Galactic Space Wars and Lunar Landing. Played from a first-person perspective, the former has players shooting as many enemy ships as possible within the allotted time. Four types of ships are each worth a specific number of points. Lunar Landing is a simplified Lunar Lander clone. While controlling a lander hovering above a flat surface, players must carefully guide their ship to a landing pad before time runs out. A limited amount of fuel adds to the challenge.
