About
At the start of the simulation cells with random DNA are spawned. 99% of DNA is not viable so most die pretty quickly.
Purple gas bubbles, inspired by hydrothermal vents
White dead cells, inspired by marine snow
Colorful alive cells, inspired by the diversity of unicellular organisms
Grey rocks, inspired by rocks, duh
After a while the first viable cells appear. There is a lot of gas everywhere which can be broken down for energy, so the first cells are pretty simple. An organelle to break down gas and a DNA instruction to multiply is all it takes to conquer the world.
As primitive cells fill the world, competition for gas bubbles increase. Some cells start to break down dead bodies for additional energy. Some grow flagella to fill spaces not accessible by passively riding the water flow.
The simulated physics can present barriers for life. Cells evolve to swim upstream, into the dense gas bubble flow, specializing with smaller body size and a stronger flagellum. Life always finds a way.
First the world created physical barriers, now the cells are making them. Some cells release biomaterials that accumulate, much like real stromatolites. These materials can be broken down, but unlike gas bubbles or dead cells, doing so costs energy. As a result, they build up just like stromatolites in nature.
Biomaterials displayed as colorful circles with a square in the middle
In a strong current even multiple flagella may not be strong enough. These cells stick together after dividing, relying on each other for support. We are witnessing the birth of multicellularity!
Evolution takes a lot of time. I run the simulated worlds for weeks, waiting for evolution to happen. I implemented Steam Workshop support, so you don't have to! Some Workshop Items are not just a simple savefiles, but sequences of savefiles! Download the sequence and use the in-game "savefile list" feature, so you can step evolutionary time forward by weeks with one click!
I am just a solo dev, I could test the simulation on an RX 6750 XT, a GT 710 and an NVS 4200M. To remedy this issue I want to provide a free demo you can try out, to check if the game works on your machine.
Please make sure you have the newest drivers installed for your graphics card.
Demo limitations:
Only the smallest world size is available
No DNA editing
No Steam Workshop access
For this simulation my vision was to simulate a whole ecosystem of cells. There are many grid-like simulations, where artificial life exists in a grid. There are many game-like simulations where whole creatures are simulated. Sadly none of these fills the niche I am interested in.
I am specifically interested in the boundary of single celled and multicellular life. How did multicellular life come to be? How cells work together as an organism? How many ways can multicellularity evolve? There are only theories as the answer lies in the un-fossilized past.
To achieve this I simulate individual cells, and their individual organelles. I do not want to force multicellularity by having dedicated types of cells. Each cell can perform multiple things, can decide which organelles to grow. I want single celled life to be just as feasible and diverse as multicellular. I want the local environment to decide how the most successful life form should look like.
This simulator is my pet project, 10 years in the making! It is running entirely on the video card. You don't need a supercomputer, just a mid range card to simulate hundreds of thousands of cells. The world in the trailer is the result of running the simulation on my RX 6750 XT for a week. Hopefully the advancement of video cards makes even bigger worlds a possibility!

I'm genuinely baffled by how unexpectedly performant this simulation is. I've used a lot of evolution sims over the years, yet this one manages to handle tens of thousands of objects smoother than any others I've tried. Actually, it's even more impressive than that; I managed to run sims with over 300,000 organisms relatively smoothly on my laptop, without sacrificing simulation speed! The developer is really active in the game's Steam community hub as well as its sub "r/EvoLife." For example, I made a post detailing a bug I encountered. Within literally ONE HOUR of me posting additional details to help reproduce the bug, the developer responded. He managed to identify the issue, explain the cause, and release a new patch to fix it. Again, all within one hour. There are a lot of things I like about the game itself. Foremost among them is the tendency for biofilms to emerge where a fluid current happens to carry food particles parallel to a rock surface; cells will evolve to adhere themselves to the surface in order to exploit this predictable flow of resources. Similarly, organisms may develop the capability to form colonies by adhering to each other. And with the right "organelles," they can even share resources with their associates. The most recent major feature added at the time of my writing is "biominerals." Biominerals are a class of objects where each type has procedurally generated properties such as radius, energy content, number of bonds they're able to form, bond strength, a matrix of things they're able to bond with, and more. Organisms require certain adaptations to be able digest them, so they tend to accumulate in the environment similarly to cellulose or calcium carbonate shells in real life. In one of my simulations, one species evolved to produce a particular biomineral which forms bonds with rock surfaces, itself, and live cells such as the ones which produced it. In this manner, colonies of this species stacked multiple layers of this biomineral to construct 'coral reefs' or 'stromatolite' analogs to access nutrient flows which would otherwise be too far away from the rock surface for a typical sessile consumer to access. Remarkable!
{{{few months down the line now, the developer has continued to disrespect people that have come from me having recommended the game before this drama, i've seen that he's now banned at least 4 people from his reddit as well as 2-3 more from the steam forums. This developer is rude and properly narcissistic. He has managed to ensure that I am unable to interact with his communities in any way whatsoever due to the issues provided below. To all the people seeing this and abstaining from the game, you're welcome to send me a friend request and I can provide the screenshots from the discussion as it happened and how disrespectful the developer was when speaking with myself and my boss. I will most likely continue to make noise in this community, on videos made about it, etc. I will have my voice brought back, I will not accept this disrespect and it will live rent free in my head till I am given the respect a paying customer that wanted genuinely nothing more than to help the developer of a product he once saw as a miracle toy. Seeing that I wasted the money on this product now, in my library, it's just a sore. A terrible cancer on my wallet that I genuinely wish I could refund by this point. I've never been this disappointed in a solo dev before. Never thought i'd have to make sure that people are aware of how disgusting and toxic a developer is.}}} {THE BUG IN QUESTION HAS BEEN FIXED, but the behavior of the developer and disrespectful attitude he had towards myself and my collegues is still here, thusly, I will leave this up until i've been given the voice I deserve. I do not seek apology, I seek recognition in the mistake that you took as a community manager in regards to this here project.} (the developer and or steam has made it so that I cannot reply to comments on this post, comments that clearly add nothing to the discussion or obviously did not read any of the content of the post will be removed, hypocritical? Maybe, but if i'm unable to reply to comments that are clearly misunderstanding the post, they've got no reason to be up. I cannot directly address the things people are saying or asking.) Games developer banned me because of an assumption, wrongly accused me of harassing his very small community due to my previous name being "AI Artist" as an ironic jab at people unrelated to the product. That is my only assumption, he gave me no information and simply silenced me after a bug report and me discussing it with another user innocently, even noting my own flaws in not providing enough information to help the dev. he uses AI in his youtube content to hide his voice, uses ElevenLabs.io to generate vocals and voice overviews for his project. He is a hypocrite. Current update causes a bug in his fluid simulation, multiple users now have seen it I reported it and apparently, upset the man making this product. I have been left with no way to report bugs on a product I have paid for without discrimination for my personal hobbies or interests. My name should not be taken into account when replying to a bug that I have proposed for your product. Steam is not a 'sold as' system, if a product is released with the expectations of support being advertised in full, people should not fear that they're going to be banned from the only sources of communication set up. 8 users total experiencing the bug, 3 verbally reporting the issue, 2 have yet to be banned. I was unable to figure out how to correctly work the workshop integration to upload the save file in question with the related issues, the developer was not too happy about the time it took me to figure out his very broken workshop integration that appears to only be able to be used by himself, users are not able to post to it even after following his provided documentation. I have been silenced for trying to advertise his product and reporting an actual core technical issue with how I myself fundamentally enjoy this and that is terrible marketing. The developer refuses to engage with me or reply to my questions for further assistance. He has outright alienated me from his community with absolutely no regards as to why. I did NOTHING wrong, he deletes my posts and calls me a troll? If I could provide screenshots as proof, I would, but unfortunately steam does not allow it. what a bleeding, horrible disappointment. This was indeed a game I felt so much deep passion for that I was recommending it to family, friends and peers in the workspace. **response to developers reply, steam won't let me comment on my own review.** Honestly though, what part of that is bothering anyone to do with YOUR community? I was bothering someone UNRELATED to you, anything to do with your game or community. People COMPLETELY unrelated to anything that has ANY mention of YOU. You banned me because of something OUTSIDE of YOUR game and community, which is WRONG. If you read the review, I state WHAT community I was jabbing at with my name. My name can be changed and does not warrant you to full‑scale ban me from being able to seek help on the product you've released to paying customers. My Steam name should be of no concern to you as it was in no way offensive and in no way bothering YOU. You are using AI tools yourself; you use text‑to‑speech AI from ElevenLabs to talk over your videos. My company, as stated in the review, is not a company dedicated to reviewing your game, rather a set of people that work for a company that all shared the game around it. You are deliberately ignoring clearly stated facts. You are now calling a group of people who share a passion about your product WEIRD for sharing it around, giving you more money? That's INSANE, dude. I was doing NOTHING that had ANYTHING to do with you besides reporting your bug. You fail to provide ANY full quotes. You have deleted the original post, stopping me from directly quoting my own words. You are now LYING to cover yourself up, but I have screenshots of the entire thing. It is not weird for a group of people to have a passion about something and to share it between themselves; just because we work at the same place doesn't mean anything. That's like telling you you're weird for ever having shared a game with a friend that you work with. your provided quotes straight up showcase that I have been playing this game WITH my boss. That does not mean our job is TO PLAY YOUR GAME. You are DERRANGED to think that, you are SELF ABSORBED to believe that would even exist. Your project however is one that people would study, so why chase us away for being passionate even IF that was the case? I find that baffling, I find you to be a terrible marketing lead and you desperately need to hire someone else to run your community, it's dead and you're killing it even further. Dev still sucks lol
Amazing Evolution Game/Simulation, I would like to see more evolution into higher organisms, working co-efficiently between the cells, and ability to form a cell wall around a group of cells, Also How Do you create Static Walls? You Mentioned it in your Video, but I can`t seem to find it. Maybe a button to make the cell or blob Static. A way for the cells to interact with the environment, with enough strength. Push, Pull, Eat, Excrete, Eject material. Just put everything in, and make it work. Users of this Game would probably like to have the options to experiment. Luminescence, Bio-Electronic Intervention. AI algorithm. Keep it simple, but have the capability to explore into multi complex stuff. What about some Achievements? Anyways Excellent Simulation maybe into a game, Keep it up DEVS...
I've been lost in EvoLife for hours – creating worlds, crafting species, and witnessing evolution firsthand. Even in Early Access, it's mesmerizing. The future promises biominerals, healing, and more. EvoLife's unique concept and engaged community have me totally hooked. I can't wait to see what the new version brings!
Addicting, hopefully we get more cell types. Reminds me of the old game called "cell lab". Never seen anything like it un-till now.
I don't know how many people here have had this issue I left this game on for over 5 mins and the game has not generated a world, straight up scam on my side I have an NVIDIA 3070 with a 11th gen processor If you cannot play the game, go to steam support and request a refund
This game has a lot of potential and a great developer that actively communicates with the community. I would like to see the option to make time slower than it currently is when set to one tick per second
Possibly best life and evolution simulation. I can run it for hours and hours. More complex and interesting than Bibites, much more performant, on the level of the alien project. Just with full AMD GPU support. It seems like it works on everything, even my Linux PC and AMD GPU. No need to tinker. Update 2026: Still great
Very good concept and simulation. Extremely good performance! But in the current state of (early access) the GUI is inconvenient, and many mechanics are not obvious. I would like to have more tutorials and explanations.
seems cool laggy me bad at computer dont know how too tell if have recommened thing me sad
