In Solar Supremacy, players command rival Earth-based factions vying for control of the solar system, building engines of industry, colonizing hostile worlds, and waging tactical space and ground warfare to earn Supremacy Points.
Players expand across a multi-planet map, develop settlements into Outposts, Major Cities, Advanced Cities, and Army Bases, unlock Logistics Cubes to scale their economy, and deploy armies, turrets, and dreadnoughts to secure territory and key objectives.
Supremacy Points come from planetary hegemony links, advanced infrastructure, military achievements (destroying dreadnoughts and defeating heroes), and exploration objectives, with victory going to the first player to reach 15 SP and hold it until the start of their next turn.
