This update brings a new AI system, a streamlined faction creator, faster controls, and a long list of gameplay, balance, and stability fixes driven by community feedback.
Adaptive AI
The biggest addition in v3.3. Adaptive AI is a new gameplay option that gives struggling AI factions gradual bonuses to stay competitive. The bonuses fade as they catch up, so it doesn't tip the scales permanently. If you've had games where half the galaxy collapses while one faction runs away with it, this is the fix. On by default, toggle it off in gameplay options.
AlienGPT
The custom faction creator is simpler to use. Less friction, better filtering, and more variety in generated leaders.
Controls
Function keys and number keys now let you navigate screens and respond to events without clicking through menus. If you spend a lot of time in the bottom bar or dismissing popups, this one's for you.
Gameplay & Balance
Fixes across combat abilities, executive orders, pathfinding, and fog of war. Ships make smarter travel decisions, and several systems that weren't behaving as intended have been corrected.
Improvements, Starbases & Tech
Improvement bonuses, starbase weapon ranges, and tech prerequisites have all been adjusted. More things work the way you'd expect them to, and there are more paths through the tech tree to reach the content you want.
UI
Cleaner screens, less clutter, and more information where you need it. Resource harvesting and planet info are now accessible without extra steps.
Stability
Crash fixes, reduced memory usage, and fewer visual glitches. The game handles complex scenes and transitions more reliably.
