About This Game

Breathbound is a sandbox survival and building game set on a mysterious alien world where every choice shapes the fate of the ecosystem — and your own. As a lone survivor, you must gather resources, cultivate crops, craft tools, build shelters, and expand your outpost while facing unpredictable wildlife and hostile invaders.

But survival is only the beginning. The planet’s Ecosystem Balance is constantly shifting. Maintain harmony and creatures will remain cautious, giving you space to grow and explore. Let the ecosystem collapse, and both you and the planet will begin to mutate — enemies become stronger, aggression rises, and you edge closer to becoming one of them.

Explore biomes, hunt or befriend alien creatures, uncover the planet’s secrets, and push deeper into dangerous zones to gather rare materials. Your ultimate goal: assemble the components needed to construct a starship and escape before corruption consumes everything.

Key Features

• Dynamic Ecosystem Balance — Your actions shape the planet’s behavior. Preserve the environment to reduce enemy hostility, or let it fall into chaos and face evolving threats.

• Survival & Resource Management — Monitor hunger, thirst, stamina, and health while crafting food, tools, and medical items to stay alive.

• Build Your Home on an Alien World — Design shelters, bases, farms, defenses, and machinery to thrive instead of merely survive.

• Adaptive Combat & Creature Encounters — Fight, evade, or coexist with a variety of alien species—your relationship with the ecosystem affects their behavior.

• Progression Through Exploration — Venture into increasingly dangerous regions to gather rare materials needed for advanced crafting.

• Escape the Planet — Collect all starship components and construct your vessel to break free from the collapsing world.
