The Videocart-13 cart contains two different games, Robot War and Torpedo Alley . The first game takes place on a space station where a computer malfunction has set four robots loose to hunt down the player.
Gameplay in Robot War revolves around the player trying to trick pursuing robots into one of the four electrified force fields scattered throughout the playfield. Each time the player is touched by a robot, one of the force fields disappears, resulting in a point loss for the robots. If all the robots are defeated, the player earns a point for that round.
The game also features an option for two players, where the second player takes control of the robots. Robot War comes with four game speeds, ranging from slowest to fastest.
The other game is Torpedo Alley , where players control a shore battery at the bottom of the screen and shoot at an invading fleet of ships above them.
In Torpedo Alley , each hit ship is worth a different amount of points, with the lowest ship being worth 1 point, the middle ship worth 3 points, and the highest ship worth 5 points. The game ends when a player reaches 99 points or the adjustable time limit expires.
