Imperium is a single-player 4X space strategy game about building a civilization among the stars. Begin with one colony and a single home star, then expand across a galaxy of alien worlds — researching exotic science, designing your own fleets, and bending rival empires to your will through diplomacy or open war. Every game generates a new galaxy, a new balance of power, and a new empire to call your own.
Colonize a Living Galaxy
- Explore procedurally generated galaxies ranging from a dozen systems to well over a hundred.
- Settle planets, moons, and asteroids — each with a surface you develop tile by tile.
- Construct more than 50 surface structures and orbital installations: factories, laboratories, hydroponic gardens, defense towers, embassies, and more.
- Terraform hostile worlds and uncover ancient ruins left behind by a vanished civilization.
Design Your Own Fleets
- Engineer warships from the keel up across five hull classes, from nimble scouts to colossal capital ships.
- Combine more than 90 components — power cores, drives, scanners, shields, and an arsenal of exotic weaponry.
- No two commanders fly the same fleet. Two players using identical hulls can wage completely different wars.
Research Exotic Technologies
- Advance through a tech tree of more than 60 technologies, from your first orbital shipyard to galaxy-spanning megastructures.
- Harness serious, far-future science: gravity manipulation, frequency-based weaponry, and exotic physics.
- Crown your empire with mega-projects — encircle a star with a Dyson Sphere, or bridge the void with a Starlane Gate.
Rule Through Diplomacy or War
- Share the galaxy with 21 playable species — Veylilith, Phasaryn, Oculari, Litharrak, and many more — each with its own homeworld, fleet aesthetic, soundtrack, and signature ability.
- Negotiate non-aggression pacts, trade agreements, and full alliances — or declare war and take what you want by force.
- Establish embassies and build diplomatic influence across rival courts.
- Outthink rival empires driven by distinct AI personalities and strategic postures that scheme, expand, and fight in character.
Claim Victory Your Way
- Triumph through military elimination, territorial supremacy, conquest of every home star, or by forging a galactic alliance.
- Shape every playthrough: choose your galaxy size, the number of rival empires, and the temperament of the galaxy itself.
Crafted to Be Played
- A deep 4X wrapped in a clean, modern interface — atmospheric visuals and a sci-fi soundtrack.
- Characterful AI that makes every rival empire feel like an opponent worth beating.
- Built-in modding tools let you reshape the tech tree and redesign the game's items.
A galaxy is waiting. Make it an Imperium.
