About the game

Lead a community of survivors after the zombie apocalypse. Manage your shelter, people, and limited resources while organizing expeditions into a dangerous world. Every decision has consequences in this single-player survival management and strategy game.

Original Steam description

THE WORLD HAS FALLEN. SURVIVAL IS NOW YOUR RESPONSIBILITY.

The zombie apocalypse has brought civilization to its knees. Cities have fallen, supplies are running low, and the survivors are struggling to rebuild something resembling a future.

In a world where every resource matters and every decision carries consequences, keeping people alive is only the beginning.

Under the Rust is a single-player post-apocalyptic survival management and strategy game where you lead a community of survivors, manage your shelter, organize expeditions, and make difficult decisions in a dangerous, changing world.

LEAD THE SURVIVORS

Your people are more than numbers on a screen.

Organize your survivors, assign responsibilities, manage their needs, and decide how to use their abilities when resources and opportunities are limited.

Every decision matters when the survival of the community depends on the people keeping it running.

MANAGE YOUR SHELTER

Your shelter is a place of safety, but keeping it operational requires constant attention.

Monitor essential resources, manage facilities, organize work, and respond to problems before they become disasters.

Food, water, power, equipment, and the well-being of your survivors all compete for your attention.

You won't always have enough resources to solve every problem. Sometimes survival means deciding what matters most.

EXPLORE A DANGEROUS WORLD

Survival cannot depend on staying behind closed doors forever.

Organize expeditions, investigate locations, search for valuable supplies, and make decisions about the risks your people are willing to take.

Beyond your shelter lies a world shaped by the aftermath of the zombie apocalypse, where danger and opportunity often go hand in hand.

The choices you make outside can have consequences for everyone back home.

EVERY DECISION HAS A COST

Do you risk an expedition for desperately needed supplies?

Do you prioritize repairing critical infrastructure or improving living conditions?

Do you push exhausted survivors to keep working, or give them time to recover while essential tasks remain unfinished?

There may be no perfect answer.

Your job is not to save everything. It is to make the decisions that give your people the best chance of surviving.

A WORLD THAT CONTINUES TO EVOLVE

Under the Rust is being actively developed in Early Access.

Development is focused on expanding the world beyond the shelter, deepening its interconnected management and exploration systems, and making the consequences of player decisions more meaningful.

New content, refinements, and gameplay improvements are planned throughout development, with community feedback helping shape the experience.

The world has ended. Your story of survival is just beginning.
