Alien monsters fall over Germany and have taken over the rule. Buildings throughout Germany are besieged by them. They neither shy away from the Brandenburg Gate nor from the Hofbräuhaus and Marienplatz. With the help of a cranky scientist and his assistant, the player gets involved with the rogues. Do not miss a chance to destroy your opponent with the provided weapons. Countless puzzles wait to be solved by you. With Invasion Germany, the idea of the otherwise bloodthirsty first-person shooter was enriched by a humorous version.
