Details

Overview

Imperium, developed and published by Petroff Games, is a single-player 4X space strategy title that puts you in command of a fledgling civilization. Starting with a single colony and one home star, you'll expand across a procedurally generated galaxy, balancing exploration, diplomacy, and warfare.

The game launched on November 2, 2026, and supports English, Japanese, Russian, Simplified Chinese, and Brazilian Portuguese.

Highlights

Living Galaxy: Each playthrough generates a new galaxy, ranging from a dozen systems to over a hundred, ensuring no two campaigns feel alike.
Tile-Based Colonization: Settle planets, moons, and asteroids, then develop each surface tile by tile. With more than 50 surface structures and orbital installations—factories, laboratories, and more—you can tailor your worlds to your strategy.
Custom Fleet Design: Research exotic science and design your own fleets, adapting to the threats and opportunities of your unique galaxy.
Diplomacy or War: Bend rival empires to your will through negotiation or open conflict, with the balance of power shifting each game.

Who It's For

If you enjoy grand strategy and 4X titles like Civilization or Stellaris, but prefer a more intimate, tile-based approach to planetary development, Imperium offers a fresh take. It's ideal for players who love procedural generation, deep customization, and the challenge of building an empire from a single star.

The turn-based, isometric presentation keeps the pace deliberate, making it accessible to strategy newcomers while still offering depth for veterans.
