In Eco, you enter a simulated ecosystem where thousands of plants and animals are growing and living their lives. You can build, harvest, and take resources from this environment, but every action you take will affect the world around you. An impending meteor strike threatens global destruction, so can you save the world without destroying it in the process?
Build towns and houses, take care of your farm, go hunting, construct roads and transportation systems, make clothing, generate electricity, and invent new technologies. Develop a specialization and trade goods with other players. Create your civilization how you want it to be while changing the landscape around you.
