UFOs have penetrated our solar system and are not at all friendly. Go to the defensive mission and destroy all enemy Ufo units. Fight in the universe, on the surface of the planets and also in the wormhole. Do not forget to save the other pilots of the destroyed aircraft and get extra power as a bonus.
