About the Game
Get ready to explore, discover and interact with a multitude of species as you journey among the stars. Forge a galactic empire by sending out science ships to survey and explore, while construction ships build stations around newly discovered planets. Discover buried treasures and galactic wonders as you spin a direction for your society, creating limitations and evolutions for your explorers. Alliances will form and wars will be declared.
Like all our Grand Strategy games, the adventure evolves with time. Because free updates are a part of any active Paradox game, you can continue to grow and expand your empire with new technologies and capabilities. What will you find beyond the stars? Only you can answer that.
DEEP AND VARIED EXPLORATION
Every game begins with a civilization that has just discovered the means to travel between stars and is ready to explore the galaxy. Have your science ships survey and explore anomalies, leading you into a myriad of quests, introducing strange worlds with even stranger stories and discoveries that may completely change your outcome.
STUNNING SPACE VISUALS
With characteristically complex unique planets and celestial bodies, you will enter a whirlwind of spectacles in a highly detailed universe.
INFINITE VARIATION OF SPECIES AND ADVANCED DIPLOMACY
Through customization and procedural generation, you will encounter infinitely varied races. Choose positive or negative traits, specific ideologies, limitations, evolutions or anything you can imagine. Interact with others through the advanced diplomacy system. Diplomacy is key in a proper grand strategy adventure. Adjust your strategy to your situation through negotiation and skill.
INTERSTELLAR WARFARE
An eternal cycle of war, diplomacy, suspicions and alliances await you. Defend or attack with fully customizable war fleets, where adaptation is the key to victory. Choose from an array of complex technologies when designing and customizing your ships with the complex ship designer. You have a multitude of capabilities to choose from to meet the unknown quests that await.
ENORMOUS PROCEDURAL GALAXIES
Grow and expand your empire with thousands of randomly generated planet types, galaxies, quests and monsters lurking in space.
PLAY THE WAY YOU WANT
Customize your Empire! The characters you choose, be it a murderous mushroom society or an engineering reptile race, can be customized with traits like ethics, type of technology, form of preferred space travel, type of habitat, philosophies and more. The direction of the game is based on your choices.

Hello again,
We have a quick hotfix that will allow Mods that haven't been updated for the Utopian Abundance changes pass any of the DLC checks they may have for Utopia, Synthetic Dawn, or the Humanoids Species Pack.
Stellaris 4.3.7 is now available for download via Steam and GOG, with MS Store following as soon as it passes certification.
4.3.7 ‘Cetus’ Release Notes
The DLC ownership check has been made backward compatible for any mod that happens to still include them.
Carry on!

Hello everyone,
We've just released Stellaris patch 4.3.6. This patch rolls Utopia, the Synthetic Dawn Story Pack, and Humanoids Species Pack into the base-game, as well as adds the Behemothkin portrait (available when you're logged in to your Paradox Account), as well as the Portrait Substitution system (and associated Arachnophobia/Arachnophilia modes), as well as an associated list of other fixes and technical improvements.
Please see the patch notes:
4.3.6 ‘Cetus’ Release Notes (Ongoing)
Feature
The Utopia, Synthetic Dawn, Humanoids Species Pack, and most elements of the Galaxy Edition Upgrade have been rolled into the base game.
Utopia contains:
Megastructures, Habitats, Ascension Perks, Indoctrination, Advanced Slavery, Hive Mind empires, Fanatic Purifiers, and more.
Synthetic Dawn contains:
Machine Intelligence empires, Machine Rebellions, Machine Fallen Empire, 7 machine portraits, and more.
Humanoids contains:
10 humanoid portraits, the Master Artificers, Pleasure Seekers, and Pompous Purists civics, the Clone Army origin, the humanoid shipset, and more.
A Behemothkin portrait has been added to Reptilians if you are logged in with a Paradox Account.
Added a Portrait Substitution option in Accessibility settings.
When Arachnophobia Mode is enabled, spider-like portraits are replaced with alternative artwork on your client only, with no effect on other players in multiplayer.
Arachnophilia Mode does the opposite, replacing non-spiders with spider-like portraits.
Bugfix
Leaders can no longer become too old to die.
Corrected Vipra the Vapor’s greeting audio
Performance
Players with systems capable of exceptionally high framerates can now override the default 90 FPS render cycle cap by adding refreshCap=144 (or other values) to their settings.txt. The first time you launch Stellaris after this change, it will add refreshCap=90 if it's not present. The refresh rate will still floor at 30 and cap at your monitor's refresh rate. Note that increasing this value will leave less time for the simulation loop in favor of the rendering loop, and thus may negatively affect overall performance.
Stability
Fix to a CS_SPECIES_COUNT, CS_SPECIES_INDEX OOS when playing with nascent species
Fix to a CS_COUNTRY_RESOURCES OOS
Modding
We've simplified how "very old age" is handled in code - the define is now a fixed point that makes you more likely to die if you are over 120% of your species' lifespan. As we've changed this from 100 to 1.2, you'll want to update any mods that changed this value.
The Portrait Substitutions spinner in Accessibility will load all files in the game\\gfx\\portraits\\portraits\\substitutions folder when the game starts and add them to the spinner options. See the Arachnophobia and Arachnophilia options we have provided for the process to add your own Portrait Substitutions.
Thank you for 10 years of Stellaris!
Please note: If you're experiencing issues using these DLC features after this patch, try disabling your mods and checking again.
It’s my pleasure to announce boarding has started for all passengers departing on our tour of Stellaris: Season 10, with non-stop service to the Nomads expansion alongside the Stellaris 4.4 ‘Pegasus’ update. Following our first destination, there will be a brief stopover at the Stellaris 4.5 ‘Cygnus’ Custodian release, after which our cruise will continue to the Stellaris 4.6 ‘Corona Borealis‘ update, featuring Willpower, Scenario Pack 1, and Scenario Pack 2. All passengers are welcome to acquire their ‘Vipra the Vapor’ Species Portrait at the ticketing office now.

The Stellaris 10-year anniversary is coming, and as part of that celebration, we are rolling Utopia, Synthetic Dawn, the Humanoids Species Pack, and most of the Galaxy Edition upgrade into the base game on May 11th. (The e-book, Infinite Frontiers, is being retired.)
Later on in Q2, we’re bringing you Nomads.

Build no borders. Claim no worlds.
The Galaxy is not a trophy to be seized, but a path to be taken. In Stellaris: Nomads, you will survive the void by staying in motion. While the great powers squabble over lines on the map, your civilization has realized a fundamental truth: life flourishes on the move.
[img src="{STEAM_CLAN_IMAGE}/9703436/c03463d4a11b3b3e893c527b10f005567e9dbc64.png"]
Arkships
At the very heart of every nomadic civilization lies its Arkship: a fully mobile capital that replaces worlds entirely. Customize Military, Scientific, or Civilian Arkships with specialized modules, districts, and upgrades as your Empire evolves by traveling through the stars.
[img src="{STEAM_CLAN_IMAGE}/9703436/3c30fed694c88eee42429df8cfbe3644c4d2b572.png"]
Waylines and Contracts
Chart Waylines across the stars, linking your Waystations into living networks of trade, influence, and opportunity. Your strength lies in motion, in presence, in the relationships you build from system to system. Your relations with settled empires don’t have to be antagonistic. Accept contracts, build relations, and perhaps profit a bit on the side.

A New Ambition: Defender of the Galaxy
Building upon the Crisis paths of previous releases, Ambitions are the next step of epic, empire-defining journeys that give you the choice of your ultimate role in the galaxy. In the Nomads expansion, we will transform the Defender of the Galaxy Ascension Perk into a full path that can rival the power of a Galactic Nemesis, Awakened Empire, or End Game Crisis.
Become the Galaxy’s champion by forging alliances, commanding federations and rising through the Galactic Community to assume Custodianship. Lead the fight against existential threats with a unique squadron of hero ships. Ultimate power can be used, and relinquished, for the greater good.

Stellaris: Season 10 Expansion Pass
Based on the feedback from Stellaris: Season 09, we’re making some changes to our Expansion Pass plans this year. As many of you have noticed, we’re announcing this year’s Season much later than previous years, and instead of four separate releases, we’re planning on bundling them together into fewer release moments. This frees up room for the 4.5 ‘Cygnus’ update to be a dedicated Custodian release, giving us two in 2026.
The Stellaris: Season 10 Expansion Pass is a journey through resilience and movement. Whether you are wandering the stars with Stellaris: Nomads or rooting your empire in the indomitable spirit of Stellaris: Willpower, this year redefines how empires survive, adapt, and conquer.
Stellaris: Season 10 will grant you access to all five DLCs as soon as they become available. Vipra now, Nomads later on in Q2, and Willpower and both Scenario Packs in Q4.

Nomads (Releases Q2, 2026 - $24.99)
Build no borders. Claim no worlds. In Nomads, you thrive inside colossal Arkships that carry your people, your industry, and your ambition across the stars. Move freely through the galaxy, take on Contracts from settled empires, and leave your mark by building Waystations. Nomads blaze a path across the map.
Nomadic Empires: Create empires not bound by claiming systems or colonizing Worlds.

Willpower (Releases Q4, 2026 - $24.99)
Shape Minds, Rule the Stars. In the vast expanse of the cosmos, borders are mere lines drawn on a map. Ideas, on the other hand, have no such limits.
Your empire was founded on its Ethics, the convictions that determined its course. Now is the time for those fundamental values to evolve into Ideologies with the power to sway the stars. Introducing Stellaris: Willpower, the expansion that turns your societal beliefs into a galactic force.
Your rule over systems was always just the beginning. The galaxy's minds are the true prize. You will erect monuments and Megastructures that demonstrate what your society and values can accomplish. You truly can become the thought leader of the galaxy.
Adopting an Ideology is not without its risks, however. Left unchecked, it can radicalize colonies and spark insurrection. But when nurtured with care, the right Ideology has the power to sway entire civilizations.

Rewrite the rules of engagement! This Scenario Pack flips the script of how Stellaris is normally played, making you the threat and aggressor. Whether leading an ultimate extra-dimensional invasion or battling your friends in a race for dominance, these scenarios offer a fresh, distilled way to play Stellaris.
Unbidden: Play as the Crisis in a single-player experience, and attempt to invade an advanced, late-game galaxy as the Unbidden.
King of the Hill: Stellaris gameplay focused on a small but fair map to challenge your friends in competitive experiences as you try to dominate the galaxy in a few hours of intense expansion wars.
The Stellaris: Season 10 Expansion Pass is now available for purchase for $49.49 or regional equivalent, a 20% discount over purchasing the contents individually.

Hello everyone,
A minor patch is ready for release, fixing a few issues.
4.3.2 should now be available for download via Steam, GOG, and MS Store.
Please find the change log below:
Stellaris 4.3.2 patch notes
Improvement
Fleets are now willing to fight further from the center of the system. Especially noticeable if fighting stationary targets at the edge of the system

Reduced the Empire Size penalty from colonies for Sovereign Guardianship civics by 25%

Hi all!
For the past nine years, every time a new player asked “what’s the first DLC I should buy for Stellaris”, you all pretty much unanimously said “Utopia”.
Honestly, we agree.
As part of the Stellaris 10 Year Anniversary celebrations, we are going to give EVERY Stellaris PC player the Utopia and Synthetic Dawn DLCs, and the Humanoids Species Pack.
This will grant everyone access to Hive Mind empires, Gestalt Machine Intelligences, the humanoid portraits, civics, and shipsets, and all the other features from these three DLCs.
We’re going to roll all three of these, plus most of the elements of the Galaxy Edition upgrade into the base game. (The e-book “Infinite Frontiers” will not be part of this as we plan to retire it.)
As was done with Hearts of Iron IV when a similar bundling of DLCs into the base game happened, the price of the base Stellaris game will increase by $10 (or the equivalent in local currency) when it occurs on May 11th.
Why are we telling you this now?
We wanted to be completely transparent with you before the Steam Spring sale. We know many of you will be on the lookout for new games and DLCs to add to your collection, and we believe this information will help you make a better-informed decision.
If you or a friend only wants the base game, you may want to grab it during the Spring Sale before the price change goes through.
If you were planning to buy Utopia, Synthetic Dawn, or Humanoids, we want you to be aware that these will be part of the base game in the near future. So please keep this in mind when deciding what to purchase during the Steam Spring Sale.
Thank you for ten years of exploring the wonders of the galaxy together!

The Stellaris 4.3 “Cetus” update is now available!
Internally referred to as “The Reckoning”, the “Cetus” patch boasts an impressive list of balance changes, fixes and performance improvements, while cutting back on the supercharged navies and economies that were introduced with Stellaris 4.0.
[img src="{STEAM_CLAN_IMAGE}/9703436/dc6dafd8f7ea3e8c6c535f67ee8838921a00c1eb.png"]
Cetus Design Goals and Philosophy
4.3 “Cetus” is not looking to re-create the economic and power balance of 3.x, but rather we’re establishing a new baseline of where the 4.x economy should be. The smaller economies and navies in 4.3 “Cetus” will reinvigorate early-game and mid-game challenges, adding more incentive to do things like Pacify Space Fauna, which might otherwise be a challenging barrier to bypass.
Over the course of the Open Beta we iterated over a good many of these mechanics and balance changes, some things were reworked due to Community feedback, and other things were removed entirely. Behind the scenes the Custodian programmers focused heavily on performance and stability. You should find the game significantly faster and more stable from the very start until the end-game. Thanks to everyone who left feedback and bug reports for us during the Open Beta!

Naval Capacity Changes
We have made significant changes to Navies intended to reduce the overall ship counts, and we feel that the reduced ship counts make individual ships feel more valuable and interesting. Decoupling ships' Naval Capacity usage from the Corvette Standard™ has given us the opportunity to do things like give Frigates their own niche between Corvettes and Destroyers.

Economic Changes
Major changes have been made to the economy to rebalance it to a lower level, with reductions across the board to unity generation, planetary ascensions, per pop jobs, and more.

Ascensions and Origins
We did a pass on many Ascension Paths and Origins to bring them more in-line with each other balance-wise. Cybernetics will become a little stronger relative to the other Ascensions, while Psionic and Biological Ascension Paths have had some of their runaway production bonuses toned down. Similarly, the early Ascension Origins have also received particular attention, with the objective of pushing their Ascension later into the game.
