"Sirius-4" is a plot-oriented space simulator that gives the player complete freedom of action as a hired pilot of the "Sirius" unit. The action takes place on the outskirts of human space during a turbulent time for the galaxy after a global war. While the automated drones of the defeated army continue to wage war according to their programmed mission, numerous factions are trying to fill the power vacuum in this dangerous and lawless region. In addition, there are various "independent" groups operating: pirates, fanatics, and transstellar corporations beyond government control. The player is given a unique opportunity to explore this vast and vibrant game world. Each time they venture out into space, the player can feel the pulse of humanity: hearing routine radio conversations between pilots, encountering ships flying on their own business. All of this creates a unique atmosphere of the life of a free pilot. All of this is "Sirius-4".
