[p][/p][p]Hello Stellaris Community!

Thank you all for your feedback on the 4.3 "Cetus" Open Beta. We have another update to the Open Beta for you, adding additional balance changes, bug fixes and a rework to how refugees function.

We have also have a new version of the Open Beta Feedback form, if you've previously filled out some sections on this one, please feel free to do so again so we can compare the results of the last feedback form to this one.

• [p]Refugee Attraction:[/p]

[p]Iggy on Refugees[/p][p]Hey all, Iggy here!

For a long while, I have been frustrated with how we handle Refugees in the Stellaris. Not a release goes by without them going to some strange place. Anyone remember them arriving in the Lathe during the Machine Age?

Well, I have been tinkering with some designs whenever there has been time, and not only have I refactored the logic behind the actual effect that handles refugees, but I have also introduced a new modifier to the game: Refugee Attraction!

This is a new modifier that will make empires more or less attractive when a pop group is evaluating if they should go to a certain empire. This modifier can never go below 1% so there is always a theoretical chance that a pop can flee to your dystopian empire. Additionally, pops will attempt to flee to an empire where their species is the dominant species, so if you see a bunch of humans arrive when playing the Commonwealth of Man, that probably means Earth has fallen.

These modifiers are being added to the 4.3 Open Beta, and if you are interested in the exact values, you can find them below:

Ethics:[/p]

• [p]FanPhobe: -30%[/p]
• [p]Phobe: -15%[/p]
• [p]FanPhile: 30%[/p]
• [p]Phile: 15%[/p]

[p]Civics:[/p]

• [p]Beacon of Liberty: 25%[/p]
• [p]Idealistic Foundation: 10%[/p]
• [p]Slaver Guilds: -25%[/p]
• [p]Inwards Perfection: -50%[/p]
• [p]Free Haven: 50%[/p]
• [p]Pompous Purists: -25%[/p]
• [p]Dystopian Society: -25%[/p]
• [p]Selective Kinship:[/p]
  • [p]Same Species Class: 30%[/p]
  • [p]Other Species: -20%[/p]
• [p]Experimental Sentencing: -15%[/p]
• [p]Media Conglomerate: 10%[/p]
• [p]Indentured Assets: -25%[/p]
• [p]Judicial R&D: -15%[/p]
• [p]Rogue Servitor: 30%[/p]

[p]Origins[/p]

• [p]Broken Shackles: 100%[/p]
• [p]Fear of the Dark: -10%[/p]
• [p]Necrophage: -25%[/p]

[p]Ascension Perks:[/p]

• [p]Crisis Paths: -50% (all of them)[/p]
• [p]Xeno-Compatability: 100%[/p]

[p]Traditions:[/p]

• [p]Harmony - Kinship: 20%[/p]

[p]Policies[/p]

• [p]Population Controlled Allowed: -10%[/p]
• [p]Slavery Allowed: -50%[/p]
• [p]Displacement Purge Allowed: -25%[/p]
• [p]Purge Allowed: -90%[/p]

[p]Resolutions:[/p]

• [p]Greater Good Path: 10% (Scaling up to 50%)[/p]

[p]
One thing you might notice here is the lack of attraction for Egalitarian and Authoritarian. This is an intentional decision, as the modifier for Slavery is so large. I do have some aspirations to implement a war refugee effect in the game, but for now, this was a good first step.

If there is any effect in the game that you think should increase refugee attraction that I missed, please share em![/p]

• [p]Added Refugee Attraction, now Civics like Free Haven will make more refugees show up, while allowing Slavery will reduce the likelihood that people will seek refuge in your empire.[/p]
• [p]Refactored how Refugees are calculated, they are now more likely to flee to countries ruled by their own species if available and they will pick planets in a smarter manner.[/p]
• [p]Replaced threads with Threading.TaskThreadCount console command for setting or getting the worker counts for thread pools[/p]

[p]Balance​[/p]

• [p]Buffed Museum Curators slightly. Also added the Historic Reenactor job swap when combined with Warrior Culture.[/p]
• [p]Player Crisis Balancing (separate feature branch from other balancing):[/p]
  • [p]Adjusted Crisis Currency Gains across the board. Cosmogenesis and Behemoths should be a bit slower to progress than before. Nemesis will be slower to progress passively through vassal control, but faster through direct destruction.[/p]
  • [p]Crisis Perks that give Economic Bonuses now also give slight upkeep increases where appropriate.[/p]
  • [p]Cosmogenesis Difficulty Rework: Fallen Empires will now directly oppose your experiments, culminating in Total War at stage 5. If the Materialist empire is around, there will be several warnings as well as a safer, alternative path.[/p]

  • [p]The Colonial Spirit modifier (from the Lost Colony Origin) now also grants 10% pop growth (pop assembly as appropriate)[/p]
  • [p]The Storm Chaser origin can no longer build storm shelters, but will instead benefit from their effects through their capital buildings as soon as they research the related technologies.[/p]
  • [p]Storm Chasers now also get -15% devastations from storms and -10% ship damage in storms[/p]
  • [p]Storm Shelters are now slightly more effective, negating 30/45% of economic penalties instead of 25/40%[/p]
  • [p]Storm negation technology now reduces negative effects on ships by 45% per tier instead of 50% (thus capping at 90% protection in most cases)[/p]
  • [p]Slingshot to the Stars now also provides -15% cost reduction for outposts (This does not apply to Influence costs)[/p]
• [p]Bureaucrat jobs (and equivalents) now produce slightly more unity.[/p]

• [p]Rebalanced Thermotechnic Mentors:[/p]
  • [p]They no longer add additional output to other jobs anymore, but produce their own instead. This output scales with the amount of employed jobs per 100 pops, being capped at 4000 jobs per category.[/p]
  • [p]They no longer count as "Bureaucrats" anymore, but are their own job category now (important for job modifiers).[/p]
  • [p]Council position "Thermal Engineer" now reduces the upkeep of "Thermotechnic Mentors" by 2%[/p]
• [p]Dictatorial Cybervision now ACTUALLY grants a flat Cyborg job efficiency bonus and scaling Stability for Enforcers.[/p]
• [p]Fixed the max district tooltips always showing modifiers that grant additional districts to non-artificial worlds, even if you were viewing a habitat.[/p]
• [p]Fixed the max district tooltips not showing percentage modifiers to max districts.[/p]

[h3]4.3 ‘Cetus’ Open Beta Patch Notes 2025-12-12[/h3][p]Balance​[/p]

• [p]Eternal Vigilance once again no longer creates free defense platforms. Added +20% home territory ship fire rate.[/p]
  • [p]Rationale: In the current environment, the free defense platforms were too strong. The AP also created an undesirable trap for players that were not ready for the economic impact the upkeep of a huge number of defense platforms would create.[/p]
• [p]Torpedo Combat Computers (and Bio Combat Computers or Fauna Neurochips) have been renamed to Siege Combat Computers, and also add +50% / +65% / +80% / +100% damage vs. Starbases and Bombardment Damage.[/p]

[p]Bugfix​[/p]
