TV Arcade Series: Gunfighter / Moonship Battle is a cartridge that contains two different games.

Gunfighter is a shoot out game set in the wild west similar to the arcade game Gun Fight. It can be played by two human players or against an AI opponent. Both players can move their gun men up and down and shoot at the enemy. A cactus in the middle of the screen offers some protection. Holding down the fire button leads to two bullets being fired but at a slower speed. The game lasts two minutes and the player with the most hits wins.

Moonship Battle is also a one-on-one shooting game but takes place in space and is for two players only. Unlike Gunfighter the players can move around and shoot both horizontally, vertically and at angles. The aim is to destroy the opponent's moonship by firing rockets. Each player has an energy level which starts at 100 and decreases when moving around, firing rockets, receiving hits and colliding. Once a ship has all of its energy depleted the opponent wins the game.
