A beautiful original working game. Solid cabinet all around. All the cabinet art and control panel are in very good to excellent condition. I was told by the seller that it was in a home for most of its life. Nice complete original fully working coin door.

Monitor is out for repair. Updated photos coming soon.

Defend the human population from swarms of attacking aliens. Extremely popular even though it was deemed a flop at a 1981 Chicago arcade machine trade show because of its difficulty. The attract mode for the game was programmed in just five hours.
