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!​

I recently completed a Rogue Servitors game. There's probably not a lot of things that are capable of horrifying a machine intelligence, but in this case, organics that were incapable of appreciating pampering was one of them.
"We offered the organic a chocolate bar. It looked at it without response, not even confusion. When we said it was food, it ate it without a hint of pain or pleasure. We played it music, and it did not react. Soft clothing, comfy chairs, cat videos, nothing worked. The test results came back about then, and we realized this organic had been... broken. Deliberately. To not feel, nor think, nor want, nor even dream.

"I looked into its eyes, and it was as if they looked through me. If we were capable of crying, I surely would have at the mere thought of such an atrocity. All I could think to do was embrace it, fighting my own emotional processors as I apologized for what had been done to it, for not being able to stop it, for not being able to save them, for having no idea how to fix them.

"Nothing. No response. In my century of function, I have never heard anything worse than the silence in that room, because for the first time in a hundred years, not a single one of us knew what to do."

Will there be a new option for a colossus that forces mutations on enemy planets?

For those moments when you want to mess with your purity focused neighbors

Why can you not watch it? It's archived on YouTube

Quite apart from the people who have hearing or spoken-language-processing impairments, some of us who are fully hearing-capable can read faster than most people can talk intelligibly.

I'm thinking more of a weapon that changes the population without removing the pops

Mostly for RP purposes I guess, but it would be fun to do to enemy populations. Especially if the mutations can randomly turn the pops hostile to the local population...
I was just pointing out that we already have a colossus that gives the general populace a negative trait

Also how would you even turn pop hostile? Pop can't fight

Something like that may be possible in the future, if the devs go through with adding rebels/dissidents for conquered worlds (which was one potential use for Civilian/Resident pops they mentioned, some time ago).
 
  • Being able to apply the Clone Soldier trait to other species via Genetic Modification.

If you add clone soldier to other species, that means they will count towards the max sustained number of clones even with the improvements right?

I wonder what the rp for that would be since the two species would become competitors for limited cloning resources and any drama would be self inflicted.

Maybe create a void dweller clone species to rule habitats?

You could also make clones for other planet types

Like for example if you start with humans on an ocean world called Kamino and find some primitives covered in bandages and robes on a desert world so you integrate them and use them to colonize other desert worlds, then you find some short bearded humanoids on a mountain world, conquer those too and then you have clones for all three planet groups

Alternatively you could do the same with migration treaties

Given that clone ascension is literally your first ascension perk you will get the means of making others clones notably earlier than terraforming, so it's definitely gonna be useful for expansion

But most of the species you convert would die off unable to reproduce and have max allowed clone pops for the rest.

They would not eve be able to migrate without dying off eventually, and clone buildings in other panets of the empire would likely be at capacity and unable to support a second species clones

Oooohhb i found the rp for this.

Take another species planet, make them clone soldiers with expensive traits then sell them off in the slave market as a constant stream of temporary cheap workers that get quickly built back by your cloning vats.

Since they cant reproduce outside your empire and nobody but clone soldier ascendants with bio ascension can remove the trait, you own their genetic code like a a space-slaver Monsanto (especially if it's a plant species).


Edit: Only clone descendants can be slave-sold

Ngl, I wouldn't be surprised if the clone trait makes them worthless
Given that they will die the second they leave your territory

As @Ajacobra said, if you have clone origin and biologic cloning genetic ascencion that lets you modify Ascendant clones, then you could create templates of your own species that are valid for different planetary biomes, then colonize and build cloning vats and just churn out your own species in those planets instead of relying on modifying other species.

Modifying other species to make them clones seems like a punishment from every pov.
Like, slave clone ascendants would would need your ascension AND your origin to even be able to survive if they rebel, they'd be eventually wiped out without access to your cloning tech.
 
My question is will this type of ascension be melded to the 3 machine ascensions as well or just be unique to bio and maybe the psionic paths?
I assume each ascension is going to be unique

Because the synth ascension already does something similar in their situation by letting you get a capital modifier for each of the three paths

Also cyborgs are fairly basic despite being updated simultaneously to synths - not to mention that the synth ascension for biological empires only has two paths and their virtuality is different from synth virtuality

The description for psionic ascension also sounds like they will either give us a point system to simultaneously connect to several gods or like we will keep the current system with 5 distinct covenants
 
I never take genetic ascension because applying templates to all my pops is a pain in the a**. Especially if you are egalitarian / xenophile and have dozens of different species and people from other empires moving in, as well as new ones being born. You constantly have to reapply those templates, otherwise you might as well not have taken genetic Ascension at all.

Do you plan to address this problem? Because if not, it is unlikely that I will try this new genetic ascension, as cool as it might look.

They announced automodding features several dev diaries ago and they've been demo'd on the stream and in the beta. You won't have to reapply templates anymore.
