Zarzon (ザルゾン, ザーゾン), also known as Satan of Saturn (サタン・オブ・サターン), is a 1981 fixed shooter arcade game developed and manufactured by SNK and licensed to Taito for North American release. The gameplay is a variation of Space Invaders.
Fly your spaceship to Saturn and destroy as many "Satans" as possible. Additional bonus points can be accumulated by destroying the comet or attacking dragonflies. An additional spaceship is awarded if the player's score reaches 5,000 or 10,000 points. If the attacking UFOs or enemy rockets are destroyed, points will be scored. The game progresses through four different screens.
The game has a 1up and 2up player score and High Score tallied at the top of the screen. The arcade cabinet has one joystick to move the spaceship left and right and guide the missiles.
The Zarzon upright arcade cabinet appeared in the 1983 film Joysticks. Zarzon, like many arcade games, uses a character based display. The screen is divided up into individual characters. Each character is usually 8 pixels.
