  • Imperium Stellarum is free to play.

    No ads. No micro-transactions. No loot boxes. No shop. No user-tracking. No way to spend money on the game.

    It will cost you time to play, though 🤔.

  • Customize your ship blueprints by deciding which modules to install.

    Fast ships with lots of weapons and no defense? Slow ships with long range weapons and heavy armour or shields? A mixture of both? You decide.

  • A new map is generated for each game. Map dimensions can be varied for smaller or bigger games.

    Stars and planets are randomly generated.

    No two games are the same.

  • Imperium Stellarum is free and open source software.

    The sourcecode is availble on github with a permissible license. If you want, read the sourcecode, fork it and use it - or parts of it - for your own game.

  • eXplore the galaxy. eXpand your empire. eXploit your neighbours. eXterminate your enemies.
