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.
