Ack-Ack Attack! is a now freeware game by Kurt W. Dekker. This game takes the classic “Paratrooper” (or Sabotage) game and takes it to quite the extreme. For those that don’t know those games, gameplay is rather easy. You control an anti-air gun. Helicopters fly in, dropping paratroopers. If 4 paratroopers land on one side of you, they work together to blow up your gun emplacement and it’s game over. The objective is thus to shoot down both the helicopters and the paratroopers as fast as possible.
