Star Imperium

Star Imperium is a sci-fi collectible card and deck-building strategy game where two commanders wage war across the stars, each defending a home planet. Marshal Ships, Soldiers, Forces, and Actions, powered by five resource factions — Anti-Matter, Crystals, Light, Metals, and Organics.

⚔ Conquer a living galaxy

Choose your faction and wage a single-player campaign across a galaxy that fights back. Capture planet after planet, defend your holdings against rival AI empires, and grow your war effort turn by turn.

🃏 Collect, build, and trade

Earn and collect cards as you play, assemble them into 50-card decks in the deck builder, and trade with other commanders online to complete your collection.

🚀 Command the battlefield

Outmaneuver your opponent through a tactical combat system of boarding, blocking, and first strike, all while contending with game-changing Forces. Break the enemy's home planet to win — but it takes more than a fleet in orbit.

🛰 Battle in online PvP

Take your decks beyond the campaign and face live opponents in head-to-head online PvP — where the sharper deck and the smarter commander wins.

Five Factions. Five Apocalypses.

Every faction is a future humanity already fears — and one someone, somewhere, would choose. Which one calls to you?

SEMCo — Capitalism as a god. The Baven strip-mined their own homeworld until it had no surface left, only mines dug inside mines. Profit rules; the rich own everything and the rest starve. Your planet's metals are next on the ledger.

Children of the First — The machines outlived their makers, and now they hunt everything that still breathes. Destroy one and it simply reloads its last save. They do not tire. They do not forget. They do not stop.

New Age Vision — They engineered themselves past hunger, past aging, past humanity itself. Flawless, deathless, and certain that every lesser race exists only to be perfected — or replaced.

The Silence — A race that warred itself to a toxic cinder and drew one conclusion: sentience is the disease. Armed with anti-matter, they have come to cure the galaxy of life entirely.

Ministry of Ka — One god above all others, and every living thing will kneel — converted or extinguished. Their faithful do not fear death. They welcome it in Ka's name.

Build your fleet. Choose your front. Decide which future is worth fighting for — or worth ending. fighting for — or worth ending.
