Stellaris Dev Diary #378 - Genetic Ascension, Traditions, and Advanced Governments

Hello Stellaris community!
I’m PDS_Bojj, a content designer on Stellaris, and as someone with a deep love for storytelling, weird science, and moral quandaries wrapped in biotech horror, working on BioGenesis has been an absolute joy. This expansion dives deep (like deep deep) into what it means to reshape life, not just physically, but culturally, philosophically, and even politically.

In today’s diary, I’m thrilled to share a look at something we’ve been brewing in the gene-vats for a while now: Biomorphosis, our brand-new Genetic Ascension path, and all the squishy systems that come with it: situations, modular traditions, and yes, even genetically-themed Advanced Authorities! It’s evolution, but make it playable.

So whether you're here for the cloned bureaucrats, the flawless über-citizens, or the writhing mutation-hives of your dreams… Auntie Bojj has got you covered!

Let’s dive in!

The Biomorphosis Situation​

AD_4nXdWPu3GMovJXg9Y6-aL-RNSikAf8MahyWbVV8JfSVaJosncGdX2NzNJsKqDWjzCT30qakQquah7NZy5dtNl3hevHtmzfQbiJrJmwXirG26yazwcfDM0_MfQi6TciT2KsKgrbrbU8Q

Biomorphosis: Why not jump-start the future of our species?
In BioGenesis, we’ve reimagined the Genetic Ascension path into something more dynamic, thematic, and, dare I say… organic. Welcome to Biomorphosis, a Situation that unfolds over three stages, each one a critical turning point in your species’ transformation.​

AD_4nXcwjjMJw4989z7APpCH3yzZjrJVgMsgNn9JvFCKA1NGUPK_vizlBhQJQvYzi0GY1jSU_W0m46Y0awJOKjXNB16py7PQ2zvqN8YIGBZ8fVagvH1y2N7PB8P1Wa8J9dCUlI-crA3jiw

Your Situation Approach is a lot like yourself… It matters.
When you take the newly named Biomorphosis Ascension Perk, you will start on the path to shape the future of your civilization through a series of decisions that define how your species evolves. At the beginning of each stage, you’ll select one of three philosophical and technological approaches to guide your development:

Purity​

The body is a sacred vessel, and perfection lies in refinement, not deviation. This approach focuses on enhancing existing traits, optimizing your species’ current genetic code, and preserving essential identity. Expect events about ideological purity, resistance to corruption (internal and external), and perhaps a little eugenics drama if you’re feeling spicy.

Cloning​

Mass production meets organic precision. Cloning enables you to scale your population quickly and efficiently, but at what cost to individuality? This path explores questions of identity, resource management, and ethical dilemmas surrounding consciousness and copyhood. You might find your leaders arguing about the souls of your citizens... or the cost-benefit analysis of their replaceability.

Mutation​

Why perfect the old when you can become something new? Mutation embraces chaos, randomness, and radical adaptation. This is the path for those who believe in progress through transformation, no matter how monstrous. As your species warps and shifts, so too will your empire! Expect powerful new traits, disturbing events, and maybe even a few limbs where there weren’t any before.​

AD_4nXdYqzwvBICYVEzM-CfXgYWZP2LXQkmpIduWFWQXpGtZ6rtVbkUXeYCBKq4LjrJAva4dcHszyQLhs1y4Exy8sd9o8WPYT27RYPTq5GhbICm4j7em6o1sGGGavHcHuFcAVMMyadRLdA

You can’t facilitate genome research without a Genomic Research Facility!
Each stage of Biomorphosis brings with it new narrative events and mechanical consequences, all tailored to your chosen approach. You can double down on a single path, or mix and match to create something truly unique; a mosaic of flesh, thought, and purpose. But don’t forget to build a Genomic Research Facility on one of your planets first, otherwise you won’t have the facilities to engage in genomic research!
So, whether you’re breeding perfect paragons, churning out clone armies, or embracing the squelching beauty of the unknowable genome, Biomorphosis offers you a chance to live your best post-Darwinian fantasy.

Modular Tradition Trees​

BioGenesis doesn’t just reshape your species, it reshapes how your empire thinks, acts, and dreams. Introducing the Modular Tradition Tree: a dynamic, partially customizable tradition system tailored to your Biomorphosis journey.​

Wanna optimize your genetic traits? All the cool kids are doing it.

AD_4nXdkQ-6YOIt3ieSw3b0Qi8Lz5gz9dq3qAr1W4CwwmvgSjkOMxU4SzjNKeLpB30_JJwXGO1ff3PcTUK8Iqx82cVi39ZPQWYmaXACtEmLWlGyTIAejYzg_QbwjTKxWOIqZnm92hkrb6w

M-U-T-A-T-I-O-N, YOU CAN CONTROL YOUR MUTATION!
As your empire progresses through the Biomorphosis Situation, the approach choices you make (Purity, Cloning, or Mutation) don’t just influence events, they also determine which Traditions you’ll gain access to in a new unique Genetic Ascension tree.

Each playthrough will feel different, because each tradition tree is built around a foundational path (again: either Purity, Cloning, or Mutation), augmented by select traditions from the other two, depending on your hybridization of choices across the three Biomorphosis stages.

At the end of the Biomorphosis situation, your empire unlocks a special ascension tradition tree. This tree is centered around your dominant approach (whichever of the three you selected the most during the situation). Additional picks in the tree will be drawn from the other approaches you dipped into, creating a hybrid structure.

So, if you’ve picked Mutation twice and Cloning once, you’ll get a Mutation-based tree with some synthetic reproductive flavor. Or, if for example, you go all in on Purity, you can expect a tradition tree as tight and controlled as your gene pool.

Each tradition within the tree reinforces the strengths and philosophies of its source:

Purity Traditions enhance species cohesion, trait optimization, and biological defense mechanisms.

Cloning Traditions focus on growth efficiency, leader replacement, and societal adaptation to mass-production living.

Mutation Traditions unlock exotic biology, unpredictable perks, and a flirtation with the unrecognizable.​

Question: Why did you do this?​

Answer: We wanted to create a system that reflects you. Not just your empire’s species, but the ideological journey you’ve taken. This modular design means you aren’t locked into one narrow vision of Genetic Ascension. It means you can experiment, mix paths, or triple-down on your biological ideals. Whether you’re crafting a society of elegant gene-purists or an unholy sprawl of ever-shifting abominations, the tradition tree will evolve with you.

Advanced Authorities​

Once you’ve completed your unique Genetic Ascension tradition tree, your empire will be ready for its next evolutionary leap, not just biologically, but politically. BioGenesis introduces a new system of Advanced Authorities, tailored to the philosophy that shaped your Biomorphosis journey.​

AD_4nXebRVcaUNc5xDnRxZCSWfTwG1iS9U457Jr8X9po2c-_FvVj546HQMSn_R-J4BxoOaREIGQd9wbs8K86mbK1TYtEeVSIEAXtLe-PD_X9YUpMF4gNrvxQ4zh3WbtK7frj8_P7HetIjQ

Everyone is equal! Even if you have tentacles coming out of your head! But also… ew.
Whether you rule through mandate, decree, profit, consensus, or collective consciousness, your ascended society will transform into a more specialized and thematically rich version of its base authority, infused with either Purity, Cloning, or Mutation ideology.

These are not just cosmetic upgrades. Each Advanced Authority comes with unique modifiers, and governing mechanics, reflecting the bio-political ideals your empire has chosen to embody.

Here are some examples of the new Advanced Authorities:​

  • Cloning Democracy, or “Cordant Multiplicity”
    This government embraces cloning technology as a testament to equality and progress. Clones stand shoulder to shoulder with natural-born individuals, their voices equally valued. The will of the people is enriched by the diversity of every perspective, clone or not.​
  • Mutation Hive Mind, or “Adaptive Dominion”
    This Hive's hyper-adaptive drones form a dynamic and ever-evolving force, leveraging constant mutation to overcome environmental and tactical challenges. Each adaptation strengthens the collective, ensuring unparalleled versatility and resilience as the Hive mind thrives in any condition.​
  • Purity Dictatorship, or “Nucleic Judiciary”
    This government wields genetic and biometric data as tools of pre-emptive justice, scrutinizing every citizen's genetic code for criminal predispositions. By intervening before transgression, it ensures order through meticulous oversight. True justice is not reactive but preventive, safeguarding society by eliminating crime at the root.​
  • Cloning Hive, or “Replicating Horde” (EDIT: I mistakenly wrote Cloning Megacorp here, but it should be Cloning Hive. OOPS. - Bojj)
    Advanced cloning technology drives the relentless production of genetically identical drones, each engineered for perfect efficiency and unity. Obeying the innate command to go forth and multiply, this hive intends to blot out the stars.​
  • Mutation Empire, or “Genomic Expansionist”
    Embracing the unpredictable power of random mutation, this empire taps into untold potential, fostering innovations and abilities that traditional methods could never achieve. In the race for dominance, the chaos of mutation becomes their greatest advantage, propelling them toward unrivaled supremacy.​
  • Purity Oligarchy, or “Eugenic Hierarchy”
    Absolute power must be entrusted to the genetically ordained elite, the purest and most capable stewards of this civilization's destiny. Beneath them, each citizen fulfills a predefined role, meticulously tailored to their inherited genetic potential. Contentment flows not from ambition, but from accepting one's designated purpose.​

Tailored to Your Path​

Each of the three Biomorphosis philosophies (Purity, Cloning, and Mutation) has its own flavor of Authority type. That’s 18 total Advanced Authorities, all designed to express a vision of what society has become in the aftermath of biological transcendence.

Choosing your Advanced Authority is a crowning moment. It’s a reflection of your empire’s journey from mere organic matter to a society reborn in gene-forged glory.

That’s all from me for now. Thanks so much for reading! May your biomass be bountiful, your cloning vats efficient, and your mutations... mostly non-lethal.

Stay curious, stay squishy,
PDS_Bojj

A Clone Interlude​

Hey, Alfray Stryke jumping in here as I’ve seen a lot of questions of “How does the Clone Army origin interact with BioGenesis??1!”

To start with, as a Clone Army origin you will be prevented from undertaking Biomorphosis until you’ve unlocked your genetic potential however, once you’ve done so you could even take the ascension perk as your first AP.​

AD_4nXfMrsa6zLBZSi4ut12RP0Ty66p8AzgwBP9n_CHEnPhDVtRJvLnlHgk87Xq6aWPZFRWYVh-o7XFhLt282n84AN0sowde3g_HNyn386M9X80dcslGtyviDn5Ppexub2x0LCeFYi9-fQ

How do you unlock your genetic potential, you ask? By completing either the Clone Fertility or Clone Potential special projects.

AD_4nXe-WTF7SrsYagYe7De426Kz1Kwrty4HY-02E0smSbRh233bhZPi3IIbA_cVqM3XEWm79iyxqGo_LSgrdMOSfzE8AeVKKb82wBYx6BoMxfp9A2NUm1P5D0-XuLNJ3klnpEpd7BbFfw


AD_4nXdO_Ex68SPW3Mv8GuJQb-QAFt7kH5eQIOIYt6ya5FtdRf8dx3VtPfCwWBE2iYiv3BMjrFK7tsrvPW91GKWLlRGTTAc-SD9dD204Y-vSwzx5A-zlZIAhf91HIzGGc0DS3hI5vaSXDA
Clone Fertility makes your species capable of reproduction once more and allows you to undergo Biomorphosis with the complete freedom of any path you desire.

Clone Potential however means that your species remains as infertile clones and as such locks you to an upgraded version of the Cloning path if you undertake Biomorphosis. This upgraded Cloning path grants the following, in addition to the regular rewards:​
  • The ability to genetically modify Clone Soldier species.​
  • Regular Clone Vats, Genomic Research Facilities and Medical Buildings increase the number of Clone Soldiers sustained per planet.​
  • Being able to apply the Clone Soldier trait to other species via Genetic Modification.​

Next Week​

Next week we’ll be exploring Phenotype Traits and the Evolutionary Predators Origin.

See you then!​

No seriously, I am baffled that this is considered a good idea!
After the Synthetic Dawn we all can conclude that the WORSE part was the situation:
You have to suffer through identical pages of filler text EVERY SINGLE TIME you want to select a ascension path.
They matter for absolutely NOTHING! Sacrifice more research - get more good - the end!
And meanwhile the 3 tradition trees are fantastic!

So instead of getting rid of the situation formula, that clearly doesn't work for this purpose - You double down...
Except now I cant even click through the filler text in fears that it will ruin my tradition tree.

Guess it will take 8 more years for you to admit this mistake.

I like what you have presented from a mechanical point of view and the fluff seems to be written well.

But I have one major caveat. As diverse as the paths one might take here are, I feel that there is a distinct lack of flavour for utopian/good/humanist/sapientcentric empires. Which is a major setback for someone who has most fun playing naught but utopian empires trying to wrench a bit of universal prosperity for all of sapientkind out of the clutches of an uncaring galaxy - which I have done for pretty much the last 500hrs playing Stellaris.

Is this just a skewed selection or are these kind of choices truely not really available?

I mean it is the state mandate that fundamentally changes your entire species / empire by force. They may use propaganda to align the people but generally speaking it feels very autoritative and it's never really something you naturally slip into organically but which is always the result of the state setting a goal, distributing resources and then making it final.

Very much my thoughts.
It would be nice if there are an Ascension Perk that blocks all Ascension Paths, but allows your POPs to ascend individually. So you get an empire mostly of normal people, but also with POPs that have ascended in many different ways by their own choice. You don't get any Advanced Authorities, but your POPs are very varied and you can promote ay Ascensions on a planet for a perdiod of time.

I think that is a very selective reading, as most in Stellaris is left vague to leave room for personal storytelling. I have always interpreted it as such that it could also just mean that so many people in a society chose to embrace an ascension path that on the scale of pops it is as if it was universally mandated. You can go that authoritarian way, but for an egalitarian/xenophile empire that does not make much sense flavour-wise.

Gimme a minute to have thoughts beyond incoherent screaming into a pillow in joy................. okay done-

All this is huge. My compliments to whoever came up with the idea to make Genetic ascension modular like the strands of DNA that're being played with like a ball of yarn, and to everyone who's been bringing it to life! You all do great work - yes, even you, with the imposter syndrome!

In particular, deeply adore the Clone Army origin changes. 100 clone pops empire wide just felt... unimmersive. An understandable gameplay design decision for a very particular strategy! But it made my brain itch - didn't really make sense on clones. This, this makes sense and is so much more clever than any tweaks I've seen suggested. I do, however, hope that some other origin in the future can fill the niche pre-Biogenesis Clone Army left behind. It was mechanically interesting and entirely worth playing, and I wanna see it come back in a more fitting form! Heck, maybe that's how energy beings will finally manifest (joking)-

One thing I have noticed is that the majority of specialized governments tend towards the dystopian, it looks like Biogenesis will continue/accelerate that trends? Is it intended that Ascension is inherently supposed to be a social ill from the narrative perspective?
I don't know about a majority. Its certainly easy to think of many of them as dystopian. But I'm not certain I'd agree with that assessment inherently for a good chunk of them. While its probably easy to take any 'advance government' and say, 'see this is how you make it dystopian' there are a batch that I can't see going any other way. Still, I'd say about half of them either lean towards 'not dystopian' or can be view as 'not dystopian' depending. I expect most bio-ascension authorities to run the same way.

To pick some that feel like they could be dystopian or not, depending on detailed implementation (Copied form the wiki):
  1. Imperial Transmission: Rapid mind transfer technology gives us a chance to send our fallen soldiers back to combat in fresh mechanical bodies. The same technique allows our workers to perform highly dangerous ship repairs in space. --Nothing here suggests this has to be traumatic for the individuals experiencing it nor does it have to be involuntary. It's very much similar to the diplomatic virtual authority in that regard. Of course, it could be.
  2. Dictatorial Manifold: Synced neuro-connectors and the supporting infrastructure allows a single person to control multiple synthetic bodies simultaneously. This has a tremendous and positive effect on worker productivity. --While this could be implemented as a horrid mind control thing. It could also mean that individual members of such 'multi-body systems' were custom built for the one using it. No need for it to be dystopian. Although having your boss able to be in more places than one could be a bad thing all around.
  3. Oligarchic Supervision: Holistic project management protocols and extra processing resources empower high-ranking officials to monitor multiple empire-wide edicts with unprecedented efficiency. --Although a stretch--given human nature--nothing stops personal information from being scrubbed before getting to the supervisors, making this supervision over the effectiveness of edicts, not something inherently dystopian. Not likely true, but thought I'd point it out always.
  4. Corporate Recollection: This corporation deals in buying memories, permanently erasing them from the client's brain. Vivid and intense recollections are worth more than mundane ones. The corporation then scans the data for useful intel before finally integrating it into synth mind creation process. --I have no problems with individuals willingly selling memories. So long as your corporation isn't extorting these out of people, there is nothing dystopian about this one either.
  5. Imperial Network: The imperial network allows the entire population to access whole new avenues of mass-entertainment. A massive cyberdome can be built to the capital to host ferocious cybersports with augmented athletes and broadcast this across multiple worlds. --While very 'bread and circus' themed there is no reason to think that its not just a big voluntary sports event. After all, cybernetics alone implies a high level of medical technology and so even 'ultra-violent' sports might be no more dangerous than modern ones. Even a pacifist empire might decide that violence needs an acceptable outlet. Evolution be powerful like that.
  6. Corporate Kaizen: Kaizen, the will to continuously improve, is a sound philosophy for the modern software and wetware environment. An extensive selection of upgrades affords our customer base individual achievement and the means towards social synergy. --This one is here more because megacorp is so heavily leaning towards dystopia already. There is nothing in large scale upgrades available to customers that implies dystopic outcomes.

I think, if I recall correctly, only individualist imperial and Democratic authorities don't go full dystopian for Cybernetic or Synthetic. I expect genetic is going to be a nightmare, and unless psionic gets a rework to not be entirely demon based, Ascension is going to become just another "what flavor of 40k nightmare do you want to play" further cementing the ruinous legacy of 40k reducing all pop sci-fi onto either grim-dark or grim-derp

Advanced Governments of Democracies (Egalitarians) are the ones that aren't dystopian though, and in their case it is represented this way. It's the other Authorities who are, and all the others are different flavors of authoritarianism (ruled by a small elite, ruled by an individual selected by an elite, ruled by a royal dynasty, or the democracy is corrupted by a Megacorporation).

How will UoR ending situation work with updated bio ascension (leader death events precisely)? Currently it's themed about cloning narrative. Will we see more variants based on what choices were made during biomorphosis situation?
 
Can I ask for a little feature to be added for this big update? Can we have a way to see other empires' tradition threes and APs during regular gameplay and not be in the obligation to use console commands? It could be something you have access to only if you have enough intel in the other empire, but please, understand that from a storytelling perspective is super important to be able to understand and see the other empire's culture, institutions, and way of thinking and transcending.
I only ask for a little button to click on the empire interaction screen to open up the other empire's tradition/APs menu to have a glimpse of it if I have enough intel, if I want to see a last stand or a ground battle and the other empire has Unshielding, I can picture then a BIG battle, not just a regular one, and write a great story about it.
So... please... just a button to open the other empire's trad menu, that's all. Grant me this wish, in this update or the next, or the next, or a "it will be done somewhere in the far far future" :)

Yeah, my biggest cross-every-finger-I've-got-and-then-genemodding-more wish for Secrets of the Shroud is that we get more covenant providers. Homage and reference is great, but please for the love of Zarqlaan we need variety beyond the same tired quartet. Shaper of Clay is a good start! Really hope the dev team is allowed to spread their creative wings a bit more, given the green light and time to be more imaginative. There are so many more emotions and ideals out there. Even the good ones can have drawbacks and still offer interesting gameplay.

Actually, come to that, is there any interaction with the Overtuned origin? That seems like it would at least merit custom flavor text, given how readily (and recklessly) this society's been messing about with genetics already.
Overtuned definitely feels like it would go well with either Purity or Mutation.

Would there be new additions to pre-FTL interactions with these new ascension path updates? Like the observation post decides to kidnap a member of the pre-FTL species and just starts cloning it? Or accidently unleashes a virus or pack of xenomorphs into the planet?

Any addition to stop the endless asteroid barrages.

Jup. 40K is nice when you chose to play it - be it in Stellaris or in my Deathwatch Pen & Paper group - but having it force-fed down the player's throat seems pretty much detrimental to Stellaris's sandbox experience.

back up - do non ancient clone vats support 20 clone solders or all of them?
It says medical buildings and regular clone vats increase the number of pops sustained per planet. I think this suggests the amount of Clone Soldiers is still limited, but can be further increased with those buildings.
