Fly Flash Gordon's spaceship into the mysterious Spider City, where your mission is to rescue missing spacemen, destroy all hatching pods, and destroy enemy patrol ships and disrupter generators that get in your way. The city is conquered when all of the hatching pods have been destroyed.
The game screen is divided into two sections. The upper half of the screen is a close-up view of the action, depicted as a side-view. The bottom half is a radar screen that depicts the layout of the tunneled city, your ship, the location of hatching pods and the location of disrupters. Hatching pods are destroyed by touching them. Touching them causes them to hatch, releasing young spider warriors who try to escape. Shoot at least five escaping spider warriors and you will be awarded a temporary shield.
Disrupters contain deadly debris and track your spaceship throughout the city. When you come in contact with one, you will find yourself surrounded by fast moving rubble. Shooting one of the disrupter's generators will temporarily freeze the disrupter so you can have a chance to escape. Also flying about are solo patrol ships which may be blasted, as well as lost spacemen who should be picked up and not blasted. Each time a city is conquered, bonus points and an extra ship are awarded.
