The only exciting thing about this version of Battle Zone is the blurb: 'In a barren wasteland you must fend off attacks from heat-seeking missiles and robot tanks in a final desperate struggle for survival'.
Barren is certainly the word to describe Tank Atak's graphics - a few faint lines are supposed to represent the mountainous landscape, while the tanks are large, green sitting ducks.
The player uses crosshair sights to aim his cannon at the enemy, who trundle in from the distance getting larger and larger. Then he shoots them.
When you destroy something you realise that Tank Atak's sound is as disappointing as its graphics. Vaporizing a tank produces a noise like stubbing a cigarette out in a bowl of water.
