Videocart-13 features a robot chase and a submarine shooter on one cartridge. In Robot War, players control a man surrounded by four deadly robots. The object is to destroy the robots by luring them into one of five force fields. If a player is caught, one of the force fields disappears. The game ends if the player is caught four times. Torpedo Alley has two players controlling guns at the bottom of the screen as they fire at ships moving across the top. The game ends when a player reaches 99 points or the adjustable time limit expires.
