Create virtual lifeforms whose development is shaped by a deep simulation of evolution. Guide them as they fight, mate, and adapt to the environment you have built. All the creatures in the trailer evolved on their own in the game!

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 31 → 0.43/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Ecosystem is a game about life. At its heart are evolving virtual lifeforms, who grow from synthetic DNA and live in a physically-simulated ocean. This DNA encodes everything about a creature: their skeletal structure, their mental processors and even their combat prowess.
The nervous system of a virtual lifeform is a pipeline computer where, every moment, data from sense organs passes through a network of neurons and finally contracts a muscle in a specific body part. Creatures swim just like real sea-life, applying torque at their joints to push against the water in a way coordinated to propel themselves forward.
To create life, you need only release a batch of these lifeforms into the water with random brains and bodies. Most will flail around aimlessly, but those that manage to move even slightly will get to have more offspring than the others. Ten generations later, their descendants will be talented swimmers.
It’s really satisfying to see the creatures evolve in a real sense, guided by your hand in the simulated fluid of your own world.
Whether it’s using electrical attacks to stun enemies or developing poisonous spikes to evade the jaws of predators, Ecosystem’s simulation features an in-depth combat layer.
Each creature has a range of combat statistics that will determine their role in the food chain. As a species evolves and gains a foothold, it will need to adapt to survive attacks from predators or face extinction.
If you want to take a more hands-on approach in your creatures’ evolution, a suite of tools are provided, unlocked as you progress through the game, to force certain traits in your species. From high level settings such as requiring a species to have tentacles, be a certain size, or have a set amount of body parts, to minute details such as determining the amount of drag or torque a creature may face when swimming, the simulation is yours to control.
Ecosystem features procedural worlds with a variety of options such as ocean depth and soil type, but you can go one step further and sculpt the terrain yourself, raising mountains or carving out dark caves for your predators to lurk in.
For players who want to monitor their ecosystems closely, there is a lot of data at your fingertips. We’ve got you covered for all the statistics and analysis of your world that you could possibly want - from ecosystem overviews showing population charts for both animals and plants to phylogenetic trees for individual species, allowing you to track your species evolution.
Ecosystem features Steam Workshop support, allowing you to share your species, maps and aquariums. Download other players' species from within the game and introduce them to your ecosystem and see if they have what it takes to survive.

Absolutely love and adore it. Has many ways to customize your creatures and overall a neat way to see evolution take course. I haven't gotten the most far and for some reason it wiped my save data, but overall still fun. 8/10, it's a better S.P.E.C.I.E.S
i really like that game. And i love it if you try to design fish the way they look in real life but instead of swimming like they do in reallife they start to do the craziest moves ever
NICE GAME

I'd say this game and the Sapling are the best evolution sims out there. This game abides to real life ecological principles while still being a modular experience. Almost every species parameter you can think of is available to be viewed, and therefore acted on. If the developer is open to suggestions, I'll be more than happy to add them later, but I get the feeling this game is the final intended product so I won't neg unless asked to. Very good job and I can't wait to sink more hours into this.
Cool a-life sim where u watch ur fish evolve new body plans and niches.
Excellent marine life body horror simulator. Has probably done more to convince me that evolution is fake than any and all other arguments I've heard combined and probably also space 10/10
very relaxing and fun, still even now finding new things and better ways to make things efficient, looks overwhelming to understand but trust me it didnt take too long to learn. If you like slow burning enviroment building, life evolution kinds of gameplay then this is definitely a try for you. even if you havent checked out this genre of game, try it out!
My only wish is that plants would grow at a good rate no matter the fps
