v1.55 - Introducing New Features and Major Balance Overhauls


We're excited to announce the release of GalCiv IV: Supernova v1.55, a significant step forward. This update brings a collection of new features, key balance changes, and improvements that will transform your intergalactic adventures. Here are some of the highlights:

  1. Gameplay Overhaul: Expect a major rework of the technology tree, including an entirely new approach to Exotic World colonization, Interstellar cabinet, and Space Weapons. We've fully rebalanced the AI's tech prioritization, and you can look forward to seeing them focusing more on weapons and hull research. 

  2. New Anomaly Events: We've introduced several new anomaly events to keep things fresh. If you've been tired of the "stealth field", you're in for a treat!

  3. Improved Ship Mechanics: Ships can now attack multiple times per turn as well as invade multiple times per turn if that's applicable.

  4. Custom Factions: We've improved AlienGPT and added a host of improved abilities for civilizations including new citizen types.

  5. Economy and Diplomacy Tuning: Trade routes have been revamped to be more valuable, with their value multiplier increased from 15% to 33%. Various factions, including the Banking Clan and Capitalist Society, have undergone balance tweaks to offer a more fair and engaging gameplay experience.

  6. You can move your Civ Capital. Enough said. We've also done a full balance pass on planetary improvements.
  7. Many many small and large improvements: We've been spying on you as much as we can. Or at least, we've been reading your feedback and have jammed as much as we can into this.

NOTE: This update will break the previous version's (1.51).  If you have a game in progress you want to finish, you can use the 1.51 branch. Read here to learn more.

We hope these updates will significantly improve your game experience in the GalCiv IV universe. As always, your feedback is invaluable to us, so please don't hesitate to share your thoughts on these new features and improvements.
