Round objects appeared in the sky over the city, and at the same time army soldiers appeared on the streets. Apparently, the command noticed the flying saucers long ago and a platoon of the best fighters was sent to the city. You are in their composition and must protect people from invasion. A ray is directed from each plate to the ground, in which alien robots descend. There you will meet them with heavy fire. Go straight to the beam and shoot to kill, preventing the aliens from scattering through the streets and causing damage to houses and residents in Hyper Space Defense. A fierce battle for the survival of humanity awaits you. Guests from space do not intend to leave anyone alive.
