Age of Eons drops you into a living world as a single, real simulated creature. Grow from a vulnerable hatchling to an apex adult, hunt and breed, and pass your genome on before the era's extinction loop wipes the slate. Here's how the world works.
Every world runs one era. They range from the Cambrian sea half a billion years ago to the Pleistocene steppe. Jump into any roster.
You are a real sim individual: your stats come from the species roster, and your body scale grows with each life stage. Survival is the whole game.
You spawn small and vulnerable. Learn the controls, find food and water, and stay near cover — almost everything out here can eat you.
You grow with every successful meal. Start foraging or hunting in earnest, learn the map, and read the weather and the food chain.
Near full size. Contest territory, form or join a group, and come into your species' full speed and combat profile.
Full stats and body scale. Hold territory, lead a pack or herd, and breed — mutations and size pass to your offspring.
A proven lineage. Your bloodline climbs the cross-server leaderboard — pass your genome on before the extinction loop takes the world.
Third-person, direct control. The client only asks — the server validates every move and every bite, so the anti-cheat snap-back applies to you too.
Growth stages change your body scale, the species speed cap is enforced server-side, and damage and death travel on the same signed combat stream as the AI herd — you're one animal inside the same simulation as everything else.
Six systems run underneath every world — the same ones whether or not you're logged in.
Bite force and bleed come straight from your species' roster. Manage stamina, pick your angle, and commit — death is permanent.
Every creature carries a genome. Breed for size and stats, chase rare mutations, and grow a bloodline that outlives you.
Group up within your species' natural limits, coordinate hunts, care for young, and defend the ground you claim.
A season clock, per-biome weather, and disasters reshape the world; populations boom and crash against carrying capacity.
Earn currency by surviving, hunting well, and leading — spend it on cosmetics inside a fair, no-pay-to-win model.
Every world ends. A mass-extinction event collapses the era and reseeds the next — survivors, lineages and records carry forward.
Every dedicated world runs one mode. Check the server browser to see what's live.
The full simulation — hunger, stamina, weather, herd dynamics and permanent death. The world as the game intends it.
Softer rules for exploring rosters, learning species, and building out a bloodline without the harshest survival pressure.
One life, a harsher world, higher stakes. For players who want the extinction loop to mean everything.
