Imperium

Forge an interstellar empire across a living galaxy. Explore, terraform worlds, design your fleet ship by ship, and outmaneuver twenty-one rival species through diplomacy, espionage, and war.
Windows & macOS · Single-player · Coming 2026
A 4X strategy game built for depth
Imperium begins with a single homeworld and ends with an empire spanning the stars. Every system you chart, every world you terraform, every ship you design, and every treaty you sign — or break — shapes a galaxy that keeps evolving whether you are watching or not.
It pairs the classic 4X loop with grounded sci-fi technology, cinematic art, and an atmospheric soundtrack — all wrapped in a polished interface designed to get out of your way.

What you'll command
Five interlocking systems — exploration, economy, research, warfare, and diplomacy — and the AI to test them.
Explore a living galaxy
Every game generates a fresh galaxy of stars and starlanes shrouded in fog of war. Survey systems, uncover what waits in ancient ruins, and race rivals to the worlds worth having.
Build & terraform worlds
Grow colonies tile by tile on the planet grid, terraform hostile worlds into productive ones, and raise megastructures like the Dyson Sphere and Starlane Gate.
Design your fleet
Four hull sizes per species and 70+ components to fit them with. Two commanders flying the same hulls can wage completely different wars.
Research a deep tech web
A sprawling web of interconnected technologies — gravity manipulation, frequency weaponry, spacetime engineering — that reshapes how your empire grows and fights.
Diplomacy with consequences
Earn Imperium Points, plant embassies, broker treaties, run covert operations, and turn rivals against one another. Relationships shift, sour, and recover on their own.
AI worth outsmarting
Every rival is driven by purpose-built algorithmic AI — strategy, economy, fleet, and diplomacy working together with a distinct personality. No two galaxies play out the same.

Twenty-one species
Each species brings its own homeworld biology, fleet aesthetic, signature ability, and AI personality. The empire you run is yours to master — who you share the galaxy with is what makes every game different.
