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!​

The Purity, Eugenic Hierarchie sounds like the Mesan Alignment from the Honorverse novels :)
 
One small question, will it be possible to see a democracy that segregates cloned "people"?
I think it would be fitting for clone rights to be a policy.

Are clones equal and independent beings allowed to find their own individuality? Replaceable servants? Or vessels to extend the original's continuity? These would be some of the possible options.

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.
The players actions aren't necessarily always the same as the states actions. I believe some of the Cybernetics ascension flavour text implies that the people are going all in on cybernetics themselves, and your lawmakers can't keep up and are trying to regulate and tax it more.

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.
Perhaps a society in which "purity" is defined by consensus? Every single alteration to the cultural genetic code is heavily debated on as a part of their politics, with the belief that the convergence of many viewpoints and life experiences will lead to the creation of infallible genes?

  1. 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.
  2. 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.
Corporate Recollection isn't inherently wrong, but it definitely has a dystopian flavour considering that in any society with major wealth inequality, the end result is almost certainly the poor selling off parts of their own mind for the benefit of the well-off. It's easy to compare it to a society that supports commercial trade in organs. As for Imperial Network, I could be remembering wrong, but I do think the flavour text for either the building or the job implies that it is indeed highly dangerous.

With Biomorphosis, will we be able to turn a regular bio empire into a Hive, by for instance, going full cloning?


Also, just seen the stream, with regards to trying to optimise how many civilians we should have for colonisation and their outputs, could this be tied to a policy? At the start of the game, for colonisation purposes we might want a lot so we would chose a high % civilian policy, then later in the game when colonisation is done and we want pure workforce we might go for a lower % civilian policy, losing their outputs but gaining available workforce faster. Useful, for example, when trying to fill out an encumenopolis or ringworld once we also have techs and edicts that reduce crime or modifiers to our ameneties outputs.
 
If not already suggested. Their should be an ability to later increase the capacity for ancient clone vats, or make regular clone vats able to grow your population if you take the path for clone soldier ascension. Currently if you play with the clone soldier origin you can't viable pick the ascension option if you plan as a fanatic purifier.

For Democracies that have purity Ascension, perhaps it could be played as a society where treatments for genetic diseases and risk factors is freely available to anyone who wants it.

Not mandatory, but so few people entirely opt out that on the scale of pops it's rounded to nothing.

Which is why I said:

I would consider the choice between selling your memories and death by starvation extorting people.

We are talking about a society that can replace all kinds of internal organs with machines. Dangerous, yes. Causing permanent pain and suffering in comparison to their medical technology. Assuming your gladiators are even bothered by their mechanical limbs being ripped off, only to be replaced before the next fight seems a question about your personal views on the thing.

Story? In my story driven game? The horror
Its 4X, if you haven't noticed. Not a story game.
Or do you re-read the "Pulsating Stars" anomaly with sparkling eyes for the 2456th time you get it?
No you don't, you click through that crap as fast as humanly possible.
Or you just trying to get good boy points with paradox mods? They got so many white knights like you here they wont even notice, sry pal.

An idea for something interesting for origins/ascension ....
Master speices (leaders and few elite high priest pops) with psihonic powers connected to different void gods, use their powers to biological alter thrall species....

I'm thinking more "sell your memories if you want to send your kids to college" and that kind of thing.

I found the quote; "Hosts savage cybersports with augmented athletes for the entertainment of the imperial citizens. Enhanced gladiators, athletes, and sprinters compete for our favor until damaged or dead". So could be roleplayed as just cyber-olympics, but definitely still has a bit of a dystopian tone.

The very nature of just about any corporate society is that you can very easily find yourself in need of money, and having a corporation buy your memories while erasing them from your mind is definitely very much dystopian.

Modern and possibly human corporations yes. But not necessarily true in the future or with truly alien minds. the point being it's not required to be. Not that it takes effort to see it as not-dystopian.
but definitely still has a bit of a dystopian tone.
Agreed that it has a tone of it, not that it is required to be dystopian though. I'd forgotten about that full tool tip as well.

But my point stands, nothing in the advanced authority system is pushing you to always have a dystopian society at all times.

I actually like it when I see certain events like the gas planet people or the rubricator again
And the mushroom network is especially great, there's even some anomalies that reference the mushrooms ❤️

Do I need to apply genetic modification to my main species in the ascension? What I mean is - is there a way for me to keep my main species relatively untouched but take mutation and transform my slaves into abominations?
