This article has been verified for the current PC version (3.1) of the game.

Stellaris has 124 different Steam achievements. Achievements have no in-game effects, the achievement just pops up in-game and then added to the player's Steam profile. It is possible to see the achievements sorted by the percentage of users that managed to complete each achievement by going to the game's global stats at Steam.

The difficulty of each achievement varies; some achievements are very easy (e.g. colonizing a planet), while some are extremely difficult (e.g. end-game crisis achievements). The below list groups the various achievements by a difficulty level as assessed by the wiki editors (uncategorized - UC - achievements haven't been assessed yet).

Achievements can only be gained in Ironman games. They can be earned while playing older versions of the game as long as said achievements were present in that version, as well as after any empire has attained victory.

General tips

  • Using Settings can make several achievements easier. In particular, setting the galaxy to have no other AI empires (besides Primitive Civilizations) prevents spaceborne aliens from being killed by AI empires; this is useful for getting the "Warrior of Light" achievement as wraiths tend to wander the galaxy.

List of achievements

The "Ver" column indicates in which version a certain achievement was added. Achievements cannot be earned prior to the version they were added in.

The "DI" column is for difficulty as assessed by wiki editors. VE = Very Easy, E = Easy, M = Medium, H = Hard, VH = Very Hard, I = Insane, UC = Uncategorized.

Deus Vult icon

As a spiritualistic empire, own 4 holy worlds.
Colonize 4 worlds with the Holy World modifier Best strategy is to have the Scion Origin story and be a fanatic spiritualist empire.

Turning off AI empires helps speed this up. This same effect can be achieved if the R severed head.png Head of Zarqlan Relic is obtained.
Alternatively, you can get the achievement as long as there is a Holy Guardians Fallen Empire and you take over and start to colonize the nearby Holy Worlds.

I won the Galatron and all I got was this lousy achievement.
Win the Galatron in the Reliquary or take it from another empire The Galatron is a very rare reward from the Caravaneers reliquaries. Each reliquary has a 0.5% chance of containing the Galatron, and only 6 reliquaries can be bought during a game, requiring an average of 34 games to obtain it... or you can make a save file just before you buy a reliquary, and make dozens of copies to load and discard until you find what you're looking for (Documents\Paradox Interactive\Stellaris\save games). This may also be obtained along with "Raiders of the Lost Galatron" by taking the Galatron from an AI empire that has it.

Defeat an empire that uses the Diplomatic stance supremacy.png Supremacist Diplomatic Stance with the Humiliate Wargoal To humiliate another empire, you must have a rivalry against them and no access to Ideology war goals. See Warfare. You may have to send envoys to harm relations first. For this achievement, the other empire must be in Diplomatic stance supremacy.png Supremacist Diplomatic Stance at the time of war declaration.
Detailed walkthrough

Create a new custom empire that is Fanatic Militarist.png Fanatic Militarist and Authoritarian.png Authoritarian, has the Civic nationalistic zeal.png Nationalistic Zeal and Civic warrior culture.png Warrior Culture civics, and which has a founder species with the Conformists.png Conformists, Fleeting.png Fleeting, and Trait traditional.png Traditional traits.
Save this empire then go back to the empire selection screen and change its spawning mode to Forced. Make sure no other empires are set to the forced spawning mode and then start a new game using an empire of your choice on a small galaxy with:

  • 1 AI Empire.
  • No Fallen Empires and Marauder Empires.
  • Tech/Tradition cost set to 0.25x.
  • Ironman Mode on.

This sets up a game with you vs. the AI empire defined earlier. When the AI completes the Supremacy tradition tree it should immediately switch to the Diplomatic stance supremacy.png Supremacist Diplomatic Stance. The AI can complete the Supremacy tradition tree early, a mere 7 years in to the game, or it may complete it later such as around 40-50 years in.

When the AI finishes the Supremacy tradition tree it will prefer to switch to or stay in the Supremacist Diplomatic Stance if:

  • Another regular empire is not in the Supremacist Diplomatic Stance or, if they are, the other empires fleet power is not overwhelming.
  • All neighbouring empires have equivalent or weaker fleet power.
  • The AI is still planning to expand (when it starts to run out of room it seems to prefer the Belligerent diplomatic stance).
  • The AI is not Pacifist.png Pacifist - if the AI shifts ethics to pacifist at any time then restart.

Play normally, find the AI, send envoys to improve relations (to discourage it from declaring war on you) and monitor the AI's diplomatic stance. When it changes to Supremacy build up your fleet to equivalent power and when ready, verify that the AI's diplomatic stance still shows Supremacy and then send envoys to harm relations, rival the AI, and declare a humiliation war. When you win the AI is forced out of the Supremacist Diplomatic Stance and the achievement is obtained.

As Galactic Custodian, defeat the end-game Crisis and then end the title rather than finishing your term
Become Galactic Custodian, defeat the end-game Crisis, and then end the Custodianship before finishing your term. This can be done more easily using a mid-game Crisis to become the Custodian. Then approve the Galaxy Defense Force and built an army to be prepared for the end-game Crisis. The term limit is 30 years, but you can increase it with the resolution: Extend Custodianship. After defeating the Crisis, approve the resolution: End Custodianship. 3.0 H

Lead a rebellion that successfully deposes the Galactic Emperor
With the Galactic Imperium proclaimed, be the instigator of a successful rebellion. You will need to Enforce Demands, not Status Quo, to unlock this achievement. The hardest part is getting an AI empire to nominate itself the Galactic Custodian and later to proclaim the Galactic Imperium. There are some ways to improve the chances or force an AI empire into this role. Once the AI is Galactic Emperor, you have to bring them down by undermining their authority and sparking a rebellion. You can choose one of these paths:
The waiting game

Increase the council size to 5 (the maximum) and enable veto power. Wait for a crisis to trigger and contain it but don't let it be destroyed. Either veto or quickly pass any resolutions by other council members to free their proposal slots. Ideally, an authoritarian empire nominates itself, as they are more likely to proclaim the Galactic Imperium later. Once a suitable AI empire nominates itself, start building a spy network on them. Support their nomination and any term extensions, but veto the creation of the Galactic Defense Force. Once the Imperium has been proclaimed, assign envoys to undermine imperial influence. When it is low enough, use your spy to start the rebellion. You can also use an operation to lower imperial authority if envoys are not enough. Be ready to fight the Emperor and any loyalists (which can be everyone except you and your vassals). Avoid making claims (and give up exisiting claims), as the "demanding unoccupied system/planet" surrender acceptance malus applies, despite the fact that you cannot conquer systems with this war goal and casus belli.

AI rebellion
  • Have Tech robotic workers.png Robotic Workers and Tech droid workers.png Droids tech or Tech synthetic workers.png Synthetics tech. Allow AI Servitude, but do not give your droid population full Citizen Rights. It is important that you do not set the Artificial Intelligence Policy to Outlawed as that will turn the AI rebellion into Civic machine terminator.png Determined Exterminator and they will not be able to participate in diplomacy later. See also AI rebellion.
  • Nominate yourself as the Calactic Custodian, then remove the term limit and proclaim the Galactic Imperium. When the Machine Uprising happens, you are given the option to play as the machine empire (the second option in red). When you do, you are playing against your former empire, which will still be the Imperial Core. White-peace the civil war. After a while, you will be given the option to join the Galactic Imperium. Do that and then undermine Imperial Authority via the Espionage System. Once your intel is high enough, ignite the rebellion with your spies.
The multiplayer trick

You can host your singleplayer game in a multiplayer session. When you host/join a multiplayer game, you are given the full list of empires to control. You can pick one that you want to designate as the Imperial Core and push them towards this goal.

  • Preparations:
    • You should be a member of the Galactic Council and have enough Diplomatic Weight to influence the resolution results against possible resistance.
    • The target empire must be a member of the Galactic Council. Before making the first move, the Senate should be in recess, your option to Declare Emergency Measure should not be on cooldown, and the target empire must have 300 Influence.png Influence available. This is visible during the multiplayer hosting process.
  • Once the requirements are met, host a multiplayer game from your singleplayer savegame and choose the target empire. As that empire, put forward the resolution to become the Galactic Custodian. Return to the main menu, switch back to your original empire in the same way (also in multiplayer) and declare the new resolution an Emergency Measure. You should not have to unpause the game during this process. At this point, the resolution is on the Senate floor and you can return to your singleplayer session.
  • Later, after the Custodian was elected, you may have to repeat the process to Remove Custodianship Term Limit. A resolution that is only available to the Custodian.
  • Finally, repeat the process to Proclaim the Galactic Imperium.

After this, you are set to be a part of the Galactic Imperium with the target empire as the Imperial Core.
