Armor Attack

"The player controls a small jeep and must destroy the many tanks and helicopters that populate the war-torn cityscape that represents the game's single play area. As with many vector games of the time, all of the background graphics were created with the addition of a monitor bezel/plastic overlay; with the game itself only generating the monochrome jeeps, tanks, helicopters and the shots they fire."
