3D hard sci-fi grand strategy across a procedural galaxy. Build colonies, forge fleets, and command an interstellar empire with information constrained by the speed of light.
Unconquered Sun
SteamUnconquered Sun is a 4X hard-sci-fi grand strategy set across a procedurally generated 3D galaxy. The greatest challenge to your civilisation is not your enemies, but rather physics. Every order sent out to a fleet travels at light-speed, and each status report received is from years in the past.
Build colonies on distant worlds, construct transports and warships, send out orders and wait for the consequences.
At the heart of the game, all communications are bound by the speed of light. Fleets can be many light years away, and the messages you send to them take time to travel, and what you observe is from the past.

Every game procedurally generates a star map, a true three dimensional field of stars at huge scale. Each star has to-scale planets and orbits and realistic calculations to define them.

Set missions to survey and colonise far away star systems. Construct buildings on individual planets, including heavy industry and research. Costruct a variety of ships, from small and fast scout ships to heavy-hitting capital ships and dreadnoughts.
Fight for dominion in the galaxy. Predict competitors ahead of time to plan and deal strategies you see play out years later. Communication, logistics, and research all play a part in gaining an edge over your opponents.
