Zoar is a top view vertical shooter where the screen scrolls upwards constantly over various stages. Your aim is to fly over the surface of a planet and blast and bomb various enemy crafts and ground targets. While you blast and bomb, the enemy will fire their weapons back at you trying to destroy you and if you are hit then you lose one of three lives. After surviving a stage, you can touch an air strip to collect bonus points. Two players can play, and each player takes it in turns to play when the other player has been killed
