After intelligent civilizations found each other among the stars, they decided to unite in the planetary League. A certain order was established in the Galaxy, but recently it was under threat, because in space there were several new Black holes. No one would have paid attention to them, if not for one event. It was noted that from the black holes began to appear starships with unfamiliar identification marks. They became more and more and their behavior turned out to be aggressive. Ships began to attack the flying trade caravans, and soon attacked and destroyed to the ground a couple of small planets. It is necessary to pacify the unknown invaders in Space Rift.
