In Night Gunner you are the rear gunner in the turret of a bomber aircraft under attack from enemy fighters. The screen display shows the cross wires of your gun sight and a view of the fighters as they weave randomly across the sky. You control your gun using the cursor keys and when you have an enemy fighter in your sights, shoot it down. Don't be too liberal with your ammunition, but you have a limited supply and when it is gone you are a sitting target for the enemy fighters. There are four fighters to shoot down on each mission, and each mission gets successively harder until the game ends with the loss of your third life. Your score is displayed on the screen, and a record of the highest score so far is kept.

Graphics are used to good effect in this game, although I was a little disappointed with the action; for a machine code game it seemed a little unresponsive. Because you control your fun, the enemy fighters appear to move in the opposite direction to your commands. This is a little disconcerting at first, but it makes the game more realistic and it can soon be mastered with some practice. A bit more action during each mission would liven up this game, which nevertheless is challenging and entertaining to play.
