Bombers Attack!

The map is of two opposing forces with a "Neutral Zone" in between. The units include bombers, fighters and artillery (including a long range artillery).

The goal of the game is to score Seven hits on the enemy city. Battles can occur between fighters, and bombers as well as air to ground.

It seems to be one in a series that includes Stukas Greifen an and Flieger Greifen an.

Based on the Biplanes it appears to be a product of the 1930s.
