Flak Defense is an artillery game where you must shoot down enemy bombers before they can bomb your anti aircraft battery. Find the planes on your radar scope, aim your flak cannon, fire and shoot down the bombers. Do not let them reach you. Shoot down as many bombers as possible so that you accrue game credits with which you can buy more advanced ammo types.

Flak Defense is intended to be harder and harder the more bombers you shoot down. The radar sweep is faster and faster and so is the movement speed of the bombers.

It is important to use a good strategy in Flak Defense so that a fast game speed is taken into account for late game scenarios. Try to have as much separation between planes as possible and keep them on the sides of the radar scope so that you maximize the time in which the bombers appear “stationary”. The bombers change position after each radar sweep.

Higher scores in Flak Defense can be more easily achieved by using advanced ammo (that can be bought by using the available game credits). The advanced ammo consists of faster bullets and of large area of effect ones.

Flak Defense is intended for short gameplays when the player a bit of spare time and wants to relax.
