How co-op works
Players share one persistent civilization, specializing in professions, trading goods, researching technology, and building infrastructure before a meteor strikes. Every industry alters the simulated ecosystem; constitutions, elected offices, laws, taxes, and scientific data let the community coordinate progress without ecological collapse.
About this game
Eco challenges players to construct a thriving civilization alongside others on a shared server, racing against a countdown to prevent a meteor strike. True cooperative play drives every decision, as the group must balance industrial progress with environmental survival. Every tree felled, every pollutant released, and every law passed affects the entire world.

Players specialize in professions, trade resources, craft technology, and vote on binding government policies that shape how the server operates. The simulation tracks ecological impact in real time, meaning unchecked industry can trigger droughts, extinctions, and collapse. Success depends on constant communication, negotiation, and shared planning.
Eco supports online co-op and LAN play, hosting persistent multiplayer servers where dozens of people can collaborate over days or weeks. Sessions become experiments in collective decision-making, requiring players to compromise, delegate, and hold each other accountable as they work toward a common goal under time pressure.

Frequently Asked Questions
How many players can work together on a server?
Eco supports multiplayer servers where dozens of players can collaborate simultaneously. The exact number depends on server configuration, but the game is designed for large-scale cooperative play with many people working together over persistent sessions that can last days or weeks.
Do I need to stay online the whole time, or can I join and leave?
You can join and leave as needed. Eco runs on persistent servers that continue even when you're offline, so other players keep building and the world keeps running. You can log back in to contribute when you have time, making it flexible for different schedules.
What happens if players don't cooperate or work against the group?
Since players vote on binding government laws that affect the entire server, the community can establish rules about resource use, pollution, and land rights. Poor cooperation or ignoring environmental impact can lead to ecological collapse that affects everyone, so the game naturally encourages accountability and negotiation.
Can I play this solo, or is it multiplayer-only?
While Eco includes a single-player mode, the game is fundamentally designed around cooperative multiplayer. The core challenge-balancing specialization, trading, lawmaking, and stopping the meteor-works best with multiple people collaborating on a shared server.
