Ack-Ack Attack is a fairly straightforward clone of Greg Kuperberg's Paratrooper. The player controls a stationary anti-aircraft gun at the centre bottom of the screen while enemy helicopters fly overhead and drop paratroopers, with the player's objective to destroy as many as possible. If four paratroopers land successfully on either side of the turret, it's game over.

If the game runs too slowly in DOSBox (including the play-in-browser version), press Ctrl+F12 repeatedly to increase the amount of emulated CPU cycles to about 20,000 for comfortable play.
