The world fell.
This valley
still grows.

The virus came first. Nations blamed one another. War followed, then nuclear fire. Nine out of ten people disappeared. The immune inherited a fractured world: ruined cities, mutated wildlife and factions competing for what remains.

You find a valley with water, surviving woodland and cliffs that leave only one entrance. It is defensible. It is alive. It is a beginning. Your colony must adapt as the seasons turn and the world beyond the cliffs becomes more hostile.

Illustrated cutaway buildings, articulated survivors and species-specific wildlife bring the basin into focus. Rabbits, deer, foxes and nine other species roam, pause and feed; hunting requires pursuit and work before a carcass can be harvested.

Plan rooms on a legal construction grid, place furniture inside completed supported rooms, and track real kilograms through hands and containers. Research fifty new facility purposes and build their paired stations around a shared power and water grid. Equipment tooltips expose actual item modifiers; survivor skills show earned and pending choices.
