Every world is a different
age of life on Earth.
A prehistoric survival game about fragile lives and a changing world. Begin small, learn the landscape, and leave a lineage across deep time.
In development. The scope below describes our design targets; beta availability is reviewed through the field station.
Explore every era.
From Devonian rivers to the Ice Age steppe — each era is its own world with a distinct roster, biomes, and planned records. Jump straight into any roster.
A world that lives without you.
Seasons turn, weather rolls across biomes, populations boom and crash, territory changes hands, and eras collapse on their own clock — the simulation runs whether or not you're logged in.
Living ecosystem
A season clock, per-biome weather, disasters, and predator–prey population dynamics drive a genuine food web with carrying caps and collapse — not scripted spawns.
Deep genetics
Every creature carries a genome. Mutations, rare albino lines, inbreeding penalties, and size and stat inheritance — breed a dynasty and your bloodline climbs the cross-server leaderboard.
Territory & factions
Claim ground, form packs and clans, and defend a range. Reputation, a TrailCoins economy, a market and governance all sit on top of the raw survival loop.
The extinction loop
Every world ends. A mass-extinction event collapses the era and reseeds the next — your soul reincarnates into whatever the caps allow, and lineages and records carry forward. Death is the mechanic.
