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.​

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!​

These definitely sound really dystopian, kind of expected from a "purity" theme.

I wonder what a Purity Democracy looks like, if it's on a more benevolent side or just as messed up as those.
Purity by committee. Pops vote on the standards for what is considered pure. Instead of social stratification, impure pops that rise above their station just get force-gene-modded into pure and perfect forms. (/joke)

I think, if I recall correctly, only individualist imperial and Democratic authorities don't go full dystopian for Cybernetic or Synthetic.
As far as I can tell the only authorities that are inherently full dystopian are the dictator ones.

cybernetic oligarchal feels completely dystopian to me, but the synthetic ones can be interpreted more neutral.

Imperial Synthetic are pretty neutral. Keeping copies of memories for latter analysis could be dark, or not. Depending on your views on individuality and interpretations of the nature of things. But transferring the minds out of damaged bodies into new ones rapidly to allow for dangerous work isn't really dystopian.

Imperial cybernetic are fully neutral. nothing there assumes a dystopian implementation.

corporate virtual and collective authorities aren't inherently dystopian at all.

Don't know. It doesn't feel like the advanced authorities are forcing dystopian upon you.

Wish there is an option to go full Viltrum. Go hard Purity and dramatically reduce your population and growth rate. But in exchange your ships and armies (maybe even leaders) get ridiculously powerful and stomp the Galaxy.

Now if only we could have Opressive Autocracy with Oligarchy and it would be the Orokin Empire right here
 
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.

While I largely agree with your assessment of most of these, (4 has the issue of the deleting part, because of artificial scarcity, and 3 is very police state) the not terrible options are vastly outnumbered by inherently negative ones. I foresee Biogenesis having a couple of maybe side grade options (Kaizen doesn't seem to offer a major social improvement unlike virtual democracy/imperial, or democratic individual cyborgs), probably limited to like, clone and mutation democracy, and Psionics is going to be all downside.

so purity blend with cloning would be horatio
Seriously, I would like to implement some kind of genetic horatio-like xenophobic empire in Stellaris that absorbs races, processing them into genetic material, adding to itself the maximum of genetic traits and gene points
 
It depends on the building and which traditions you have.
So you can have more than 100 clone soldiers, it's just lesser buildings (i.e. clone vats, gene clinics) can't go as high as a Ancient Clone Vat.

Does this mean that the Bioregeneration Institute Cosmogenesis building can hit 50 clones? Since it's a FE technology.

How does the ascension rework work with Overtuned?

P.S. after watching the stream: Overtuned origin lets u pick Bio asc 2nd, compared to normal 3rd or clone army 1st.

Well I am hyped for this, I'll finally be able to do what I've long wanted to do with the clone army origin and have them as rulers on all of my planets lording over all other, non-designed species!
 
Hi! This dev diary looks great, I really like the flexible tradition tree mechanic. One small question, will it be possible to see a democracy that segregates cloned "people"? Maybe I would need to go something like cloning->purity->purity? Clones are just cogs in the machine with slave rights, while the few naturally born citizens have all the political power

Neal Ashers Jain are being unleashed? Ok bow that would demand cybernetics all rolled in too with weird and strange mutations. So the people made of food made walls, now you can jump or blast thru.. even grow internal powerplants and lasers, hyperspace engines and more.. ofc those poor bugpeople(?) were also in a constant civil war of destructive reproduction. A few weirdoes got away from those biological urges and shape the universe milllions of years later.

Given that some governments mention how accepting they are I would assume that we can get some blade runner nonsense

Also makes me think of a comic I read once - there's artificial humans with some weird bumb in their neck and one of them is caught on Earth, so he gets force drafted to the Marines - during training his drill sergeant tells them "In Space no one hears you scream - unless you're a Marine!"
