Age of Eons is a living-world survival game. Spawn as a Cambrian radiodont, an Allosaurus over the Morrison floodplain, or a mammoth on the Pleistocene steppe — then grow, hunt, breed, and pass your genome on before the world's extinction loop wipes the slate and a new eon begins. Every stat is grounded in real paleontology.
From the Cambrian sea to the Ice Age steppe — each era is its own world with a distinct roster, biomes, and paleo-accurate cast. Jump straight into any roster.
Seasons turn, weather rolls across biomes, populations boom and crash, and eras collapse on their own clock — the simulation runs whether or not you're logged in.
Eight ecosystem subsystems drive a season clock, per-biome weather, disasters, and predator–prey population dynamics — a genuine food web, not scripted spawns.
Every creature carries a genome. Mutations, rare albino lines, size and stat inheritance — breed a dynasty and your bloodline climbs the cross-server leaderboard.
From the Cambrian sea to the Ice Age steppe — ten distinct worlds, each with its own roster, biomes, ambient audio, and paleo-accurate cast of creatures.
Every world ends. A mass-extinction event collapses the era and reseeds the next — the survivors, the lineages, the records all carry forward. Death is the mechanic.
Growth stages, controls, combat, breeding and the ten-era timeline — everything you need before your first spawn. →
