Adapt your strategies to cope with environmental factors and resource distribution. The Planet Screen's visual makeover includes new backgrounds, updated terrain visuals, and a neutral-colored grid. Planet Surface tiles have clear bonus icons, streamlining your management process.


Exciting New Events

Leaders possess new unique traits that test loyalty, influencing the course of your empire. For instance, leaders with a culinary dream might be tempted to open a restaurant, diverting their attention from governance. Traits like Factory Child, Culinary Dream, Duel Scar, Noble Lineage, Recovery, and Engineer trigger these intriguing events, making each leader a fascinating challenge to manage. Keep a watchful eye on their loyalty; neglecting it could lead to the rise of a breakaway colony, adding an exciting new twist to your gameplay experience.

Galaxy and Faction Updates

The galaxy has undergone a transformation with adjustments to star spawn likelihood and sector sizes. Additionally, factions have received tweaks to their conversations and traits, adding more depth to their interactions and gameplay mechanics.


User Interface and Text Improvements

We've listened to your feedback and made several user interface updates to improve the overall user experience. Additionally, text errors and typos have been fixed to ensure a seamless and polished gameplay experience.


Miscellaneous Tweaks and Fixes

The update also includes several tweaks, fixes, and balance adjustments to ensure a smoother and more enjoyable gameplay experience. Ships' culture traits no longer flip to pirates, ensuring smoother gameplay. The Siege ship's hull size changed to small for better balance. From addressing exploit issues to adjusting colony and asteroid decay rates, we've worked to refine every aspect of the game.
