No Man's Land (Gottlieb) - MAME - Shoot 'em up / Action

You control a tank with a hall effect joystick. The tank can move in 8 directions. The fire button causes the tank to shoot in the direction it is moving. On each screen, there are active and dormant enemy tanks. As the screens progress, the tanks are worth more and more, but the dormant tanks are always worth twice as much as the active ones. Of course they are well guarded! The scenery consists of a few trees and a river which you can only cross by bridge. If you shoot an active tank, one of the dormant tanks will spring to life and come after you. The object of the game is to clear the level and go on to the next one before they kill you. Each succeeding level has more enemies, and moves faster and faster.
