Sabotage

The player controls a gun turret at the bottom of the screen. The turret can swivel to cover a large area of the screen, but cannot move from its base. Helicopters fly across the screen at varying heights, dropping paratroopers. The gun may fire multiple shots at once, and the shots may destroy helicopters or shoot paratroopers. Paratroopers may be disintegrated by a direct hit, or their parachutes may be shot, in which case they will plummet to earth (splattering and dying if they were sufficiently high when the shot hit). Furthermore, destroyed helicopters turn into shrapnel, which may destroy other helicopters or paratroopers. Periodically, jets may fly by and drop bombs; the jets and bombs may be shot as well.

The player earns points by shooting helicopters, paratroopers, jets, and bombs. Firing a shell costs the player one point, so if one is playing for score, there is an incentive to conserve ammo.

The game ends when the player's turret is hit by a bomb, when a single paratrooper lands directly on the turret, or when four paratroopers safely land on either the left or right of the turret (that is four on one side, not four total). Once this happens, they are able to build a human pyramid and climb up to the turret and blow it up.
