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!​

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

There are various events that can cause a hostile army to spawn on a planet and start fighting the local garrison. I would think a random chance to trigger something similar would be relatively simple

I would argue that devolution is less a negative trait, and more temporarily exterminating said population, assuming the opponent has the technology and desire to reevolve them
 
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.
Imo it's way worse that I can't give xenos cybernetics or psionics without them defaulting to citizenship (or residency)

In that aspect all three ascensions are equally good for modifying the only pop that matter: your main species

I mean, a bad trait would be cured just as easily
Or it would get ignored because it doesn't have any impact

For example you could give a whole species the low fertility trait and they would do just fine

And even wasteful has a rather negligible impact on the economy since most people overproduce consumer goods anyways
 
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.
To be fair, you still need to manually configure the template for every pop species in your empire. Still, miles ahead of the current "a new pop from this species immigrated in and now it is reproducing so I need to again reapply the template".

Being able to copy paste templates, and set default templates for newly incorporated species would be very appreciated for someone who likes playing broken shackles :D
 

New video posted on Genetic Ascension.


Notably the video touches on how purity interacts with democracy which was discussed earlier in the thread. It seems in Democratic authorities, purity is much more about healthcare (likely eliminating genetic diseases/risk factors). And reading the advanced authority that appears on screen, it seems like individuals are free to alter their genome within the bounds of their own species.

This makes sense to me. Purity doesn't need to be defined only by adherence to a very specific ideal, it can just be "a genetically pure human is a genetically healthy human" and everything else is flexible. And if one were to take a single tradition of mutation to go along with an overall focus on purity, then there can be even more flexibility in what is considered "pure".

Nice. The descriptions of purity included things like enhancement and optimisation, so I don't think it was a stretch to see a non authoritarian version focusing on making a common, high quality template. Though the name is of course evocative.

Well, no two humans are the same, so it would be tricky to define down to the letter what exactly is pure or impure

The early stages with "they demand more rights" and a pull towards Egalitarianism gives me strong Animal Farm vibes though XD
"All animals are equal, but some are more equal than others" :p

I think if there's ambiguity as to whether a trait is within the bounds of genetic purity, the more democratic interpretation will always default to "yes".

On an individual level there will be a lot of variation, but on the scale of pops the gameplay effect is still the same "supercharging your species traits" because people aren't held back by unambiguously negative traits that have a genetic component (ie most cancers, diabetes, etc). Plus even if no one is forced to make genetic changes for the sake of their profession, enough will do so voluntarily that on the scale of pops it averages out to a more productive population.

You might also have situations like, it's not mandatory to have that gene that makes you immune to HIV inserted into your genome, but if you happen to catch HIV, guess what the recommended treatment is going to be?

As for the event, I suspect the pull towards Egalitarianism might be the start of a backlash effect that you'll have to deal with the consequences of further in the event.

156 limbs though *might* be a touch impure.

"Pure" is just a term I'm going to ignore/headcanon theres some cool future slang reason for why it's being used this way. At least for my non auth empires. Tbh I think it's badly named and should have been something more evocative of enhancement/optimisation, rather than going straight for the nazi ideology. But heyho since the mechanics don't automatically align with the latter, and are flexibile enough, it's not worth getting fussed about.

"Look Dave. We're humans. You're not supposed to graft Blorg tentacles onto yourself, and especially not *there*...."
 
Not so cheerful purity:

Watch the movie Gattaca for your fill of autoritarian eugenic racist dystyopia where you can observ genetic discriminatiin against hose born outside of regulated and mandatory eugenic programs where everyone must conform or become an outcast.
 
Do a Purity run with a mutation tradition, and they only might be.
Alternatively purify your main species and mutate the second class citizens you "integrated" by your preferred means

Or they let humans turn into angels, vampires and elves for example - certainly abhuman, but yet much better than the mindflayer abominations that a pure mutation empire would have

Or, conversely, if you're a xenophile, don't even *think* of hiring xeno leaders before you've ascended and assimilated them, as neither assimilation nor, in cybernetics' case, situation give cyborg/psionic trait to them.

*sigh*, I used to default to cybernetics for my xenophile empires as it gave every leader a cyborg trait, even the admiral from marauders, but then that got changed.

I mean, event leaders usually are better than your own guys by default, regardless of their traits

And if you hired allied leaders you probably liked their traits enough to pick them over your own guys in the first place

I don't dislike the more utopian style, but isn't the democratic Purity advanced authority flavour text a bit too similar to the Mutation one? They could go for the "purity as healthcare" angle without the "everyone is free to self modify however they want" part, that just muddies the distinction between Purity and Mutation.

Edit: For reference, "Bodily self determination is a right. The state empowers individuals to modify their vessels as they see fit. Limited only by their imagination, the body becomes the ultimate canvas" and "This society upholds the principle that each individual's body is their temple, fully under their own design and control. Within a framework of freedom and unwavering support, citizens are empowered to realize their unique potential, shaping themselves and their futures as they see fit."

At the end of the day both are democratic and both are gene modification

It's a difference if you're free to express your purity by turning yourself into an elf or vampire or if you're free to express your want to mutate yourself by growing 157 arms

There are plenty of other ways to show democratic gene modding, though. Like "this society has a taxpayer-funded initiative that makes safe and well-crafted gene models to mod yourself with, so you can become an elf or vampire without the risk of accidentally hurting yourself with reckless self-modding." As is, both authorities sound essentially identical.
