About This Game

Something went wrong in Blackpine.

An unexplained anomaly has transformed the region. Research teams sent to investigate have vanished, communications have gone silent, and dangerous creatures now roam the land.

You are sent to uncover what happened.

But Blackpine is no longer a place where survival can be taken for granted.

When the Sun Dies is a first-person, open-world survival crafting game where exploration, base building, resource management, and combat come together in a mysterious, hostile world.

Explore forests, abandoned facilities, underground caves, and mysterious locations scattered across a procedurally generated world.

Dig into the terrain, mine valuable resources, discover hidden supplies, and follow the traces left behind by missing research teams.

Every expedition brings new opportunities — and new dangers.

Gather resources, construct your shelter, and turn it into a fully functioning survival base.

• Build structures and crafting stations.

• Grow crops, cook meals, and manage food supplies.

• Craft weapons, tools, and specialized equipment.

• Repair damaged gear and improve your production.

• Research new technologies and expand your capabilities.

Your base is more than a shelter. It's the foundation of your survival.

Hunger, thirst, exhaustion, disease, and dangerous environmental conditions are constant threats.

But nature isn't your only enemy.

The Yellow Storm forces you to seek protection while creating opportunities to collect rare resources.

The Long Night brings extended darkness and relentless enemy attacks, testing everything you've prepared.

Sometimes survival means fighting. Sometimes it means knowing when to retreat.

Face dangerous mutants with different behaviors, attacks, and abilities.

Fight using melee weapons, firearms, and specialized combat skills.

Gain experience, develop your character, discover powerful equipment, and unleash devastating abilities through the Rage system.

The deeper you venture into Blackpine, the greater the challenges — and the rewards.

Follow abandoned research notes and mysterious clues to uncover the secrets of Blackpine.

Activate forgotten facilities, survive enemy waves, explore dangerous labyrinths, and confront powerful guardians.

Three mysterious Obelisks stand at the center of the region's instability.

Finding them may be the key to restoring the world.

Take on Blackpine alone or join forces with up to three friends in online co-op.

Explore, gather resources, construct your base, prepare for dangerous expeditions, and face the threats of Blackpine together.

The world is changing. The storms are coming.

How long can you survive when the sun dies?
