Nov 12, 2026 Imperium 1.0.1.16: Plain Sight
Thank you for every review, forum post and Discord message since launch. We read all of them. This update is built from what you asked for, suggested and reported, and more is on the way. From your feedback Territorial victory now depends on galaxy size: own 90% of all systems in a Small galaxy, 80% in Medium, or 70% in Large and Epic. The bar stays the same all game.

Nov 5, 2026 Imperium 1.0.1.3: Stay a While
A small fix for a bug that cost a player 45 minutes of progress. Your saves still load, and both changes apply to games in progress. F10 keeps you in your game. It used to return to the main menu without saving or asking. Quit to Main Menu in the pause menu is the way out, and it asks first. Gas giants read Gas Giant, with no size in front. Thank you for all the reports. Keep them coming!
