Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Eco is a community-based game; the players develop laws, government, and an economy to determine the success of their world. We need extensive playtesting to get the balance of our core features just right. Early Access is the perfect fit for finding an audience for this while also funding additional development.”

Approximately how long will this game be in Early Access?

“We plan to be in Early Access for 1 year.”

How is the full version planned to differ from the Early Access version?

“The full version of Eco will contain complete versions of the following:

  • A Fully fleshed out and balanced tech tree
  • A player-enforced law and governance system
  • Community mod support and API

Of course, a large bulk of the improvements will come from balancing the existing core mechanics.”

What is the current state of the Early Access version?

“Eco completed a successful Kickstarter in 2015, and has been 3 years in development.
The game is playable and contains the following features:

  • Online multiplayer
  • Single player
  • A server package for players to host and run their own games
  • Procedurally generated worlds
  • Over 30 different craft tables, with hundreds of recipes
  • A simulated ecosystem with dozens of unique species
  • Driveable Vehicles
  • Player-run economies and trade systems
  • A nutrition system where players must manage their caloric intake
  • A quest-like contract system where players can create tasks and missions for other players
  • A Programmable law system where players can propose and vote on allowable actions in their world
  • A web interface to view simulation data from the worlds that you play on

Will the game be priced differently during and after Early Access?

“Price will not change when we leave early access.”

How are you planning on involving the Community in your development process?

“We engage with the community in several places; On Steam forums, Discord, and Facebook.

Most actively, we engage on our public discord, where the development team talks directly with the community to discuss ideas, bugs, and solutions. We solicit feedback actively and engage directly with players. We also share source code with our dev-tier backers who can contribute.”

The Eco Report #3 - New Vehicle List is out!

Come check out the upcoming Bulldozer, Combine and more!

Vehicles are one of the biggest aspects of Eco still left to fully flesh out, as we currently only have a few. Their main role is to scale up the number of resources you take from the ecosystem while also scaling up the impact players have. Think worlds covered in farms, giant strip mining pits with huge piles of tailings. This update will include a big pack of new vehicles and expect more to come throughout Early Access.

  • Object spawning is now synchronized to prevent weird physics collisions that often sent objects flying
  • Fixed cut trees occasionally floating w/o gravity

  • Vehicles, rubble and trees should fall through the world much less frequently
  • Vehicle acceleration has been clamped so launching vehicles should be much more difficult

  • Fixed existing law text not getting updated when districts are renamed
  • Fixed a server crash from air pollution emitting objects, which was due to threading problems
  • Fixed a server crash that happened when double clicking 'x' on a store listing
  • Fixed a login problem that may have caused users to log in as someone else
  • On object windows, the 'Status' tab is now hidden if there is nothing on it
  • On object windows, the 'Storage' tab shows an 'empty' message if there is no linked storage on it, rather than just being empty
  • Each time you open an object window, the first tab is shown, regardless of what tab you had open when you last closed it - Unless the object is disabled, in which case the 'Status' tab is shown.

“Eco is one of the most ambitious and original concepts I've seen in a while.”
Jeffrey Matulef, EuroGamer

“Eco emerged as an unique entry to the genre that pivots on environmental and social friendly themes.”
5 / 5 – Aler Hugues, CowLevel

About This Game

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.
