About Eco


Enter the world of Eco, a fully simulated ecosystem bustling with thousands of growing plants and animals living their lives. Build, harvest, and take resources from an environment where your every action affects the world around you. An imminent meteor strike threatens global destruction. Can you save the world without destroying it in the process?



Construct buildings and towns, tend to your farm, hunt wildlife, build infrastructure and transportation, craft clothing, build power plants, and research new technologies. Specialize in a craft and trade your goods to other players. Develop your civilization and sculpt your planet.



As your civilization grows, you’ll need to analyze data from the simulation; evaluating the impact you have on your world. Use this data as evidence in proposed laws, restricting harmful activities without disrupting the advancement of technology. Balance your individual needs with the needs of community, all while maintaining the state of the ecosystem. The future of your world is in your hands.


Every organism in Eco exists as part of a detailed simulation; a disruption in one species can have cascading effects across the planet. Chop down all the trees, and habitats for creatures will be destroyed. Pollute the rivers with mining waste, and your farms will become poisoned and die. The ecosystem supplies the resources you and your community will need to stop the meteor. Manage your pollution, mining waste, hunting, and resource collection to balance your effect on this system.



Eco is built on a rich ecological simulation. All the data generated from the interaction of plants, animals, climate, and players can be searched and analyzed using in-game graphs and heat-maps. Use the collected information as scientific evidence support to proposed laws. The ability to successfully debate using scientific evidence is your greatest weapon against the destruction of your world.



Establish and maintain your own set of laws and government, which are enforced automatically by the game. Draft a proposal to limit clear-cutting in a protected forest, incentivize green energy solutions over fossil fuels by providing tax subsidies and penalties. Participate in elections for world leadership, allowing you to set tax rates and allocate community money. Use a programmable law system to make dynamic and flexible rules for the community, passing them by vote. Construct a wide variety of governments; from tightly-regulated dictator-states, to tax-and-spend subsidy programs, or even lawless communities relying on trust.



Your skills increase based on your food and shelter. By consuming a highly nutritious variety of food and building an elaborate home you will rapidly increase your skill points. Skill points can be spent on skills like farming, hunting, trade, engineering, research, and more. Contribute to the greater good while increasing your own personal success.



In the player-run economy, you achieve the most when you specialize and trade both goods and services. Create stores to buy and sell goods you need asynchronously with other players. Setup contracts within the game’s quest-like labor market, soliciting other players to perform specialized work for you in exchange for payment. Build complex crafting machines and charge a fee for players to use them. A thriving economy in Eco can be both a powerful tool for progress, or a dangerous threat to the environment.

To grease the wheels of commerce, you can create your own currencies, backed by fiat or by resources. Manage the value of your currency relative to others by setting exchange rates at asynchronous currency exchanges. Sell items at stores and collect credit from other players. Eco is designed for rich asynchronous play, allowing many players of many disciplines to contribute to one another’s goals at separate or simultaneous times.



All of the world’s resources originate from its environment, which is affected by your actions. While a meteor looms over head — set to strike the planet in thirty days — a more subtle threat grows from player-interaction with the environment. Without careful attention, ecological destruction can destroy civilization before the meteor even strikes. To ultimately succeed, you and your community will need to use the tools of government and economy to find a balance between progress and protection.

How much does Eco for PC cost right now?

Eco for PC starts at €7.98 at K4G, 72% under the €28.99 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €28.99 at Steam.

That €7.98 already includes the GCDK14DEAL coupon, so apply it at checkout or the store will show you a higher price.

10 stores carry it, 14 offers in total and 13 available right now; the figure above is the cheapest of the ones you can actually order.

That puts it 56% under its average of €17.99 since 2018, so today is a better entry point than most days of its life.

Which format should you buy?

The cheapest route is a shared account at €7.98 at K4G: you get into an account that already owns the game, but it never becomes yours. A key for your own Steam account starts at €28.99 at Steam, €21.01 more, and that is the sensible option.

The 8 Steam Gift offers start at €27.20, pricier and more prone to issues.

Which editions are on sale?

Beyond the standard edition at €7.98, there is the Early Access at €14.09 at Instant Gaming, €6.11 more. Check on the store what each one adds before paying the difference.

Can you activate it in your region?

8 of the 14 offers work on US — the Global ones plus the ones issued for your own region.

Why is one listing so expensive?

One listing is worth ignoring: the Steam gift that G2A has at €40.00 is more than 5 times the cheapest offer and is not what this game costs. The number to work from is €7.98 at K4G.

So, which Eco deal should you buy?

There is no third-party key on offer today, so the choice is between the shared account at €7.98 at K4G — cheap, but the game never becomes yours — and paying the official €28.99 for a key on your own account. Either is defensible; just know which one you are picking.

Eco is a simulation and strategy game that will allow us to create an ecosystem at our whim, with all the details. We will be able to create it and fill it with thousands of types of plants and animals, which will grow over time. Build, harvest and take resources from an environment where all your actions affect the world around you. 


Our main objective at ECO is not only to create our own ecosystem and fill it with life, but we must also take all the necessary measures to prevent the imminent impact of a meteorite from destroying all our creation. 


At the start of the game, we'll focus on building buildings and cities, caring for and managing farms, finding wildlife, building infrastructure and transportation, building power plants, and researching new technologies. And we will even be able to open up trade and craft routes with other cities. In short, we must develop our own civilization taking into account a large number of factors. 


Establish and maintain our own set of laws and governance, encourage green energy solutions on fossil fuels through subsidies and fiscal sanctions, participate in elections for global leadership, set tax rates and allocate community money,.... There are many actions that we can do in ECO, but all of them will be aimed at one single objective: to protect ourselves from the imminent and inexorable meteorite that is about to arrive. 

Most common FAQs when buying Eco for PC in digital format:

It is a key that will allow you to download the game Eco on your PC from official download platforms.
As of 03/08/2026, in United States, the best price we have found in our selection of online stores that include the key for Eco on PC is €7.98.
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Eco to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Eco, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
