About the Game

Sirius-4 is a space simulator that gives the player complete freedom of action. The game takes place in a galaxy created using a level generator, which makes each new game session unique. There are various independent groups operating in these open spaces: pirates, fanatics and supranational interstellar corporations. The player is given a unique opportunity to explore this vast and vibrant world. Every time going into space, the player will be able to feel the pulse of humanity: hear the routine radio conversations of pilots and encounter ships tracking their routes. All this creates a unique atmosphere of a free pilot's life. All this is Sirius-4.
