You were a scientist on a space exploration expedition studying black hole anomalies. During your research, you encountered an alien life form. And the aliens were absolutely hostile. They destroyed everything they saw and there could be no negotiations. Soon, aliens attacked a remote planet where mining was carried out. So it became clear that the business would not end with one research station. Later it became known that the aliens had destroyed several military groups who had arrived to defend the base. Soon there was a signal that not far from you there is a small ship that will take away the surviving members of the expedition. You were taken from the station, but along with you, the aliens made their way onto the ship. The ship is heading straight for Earth ...
