Explore

Head out across an overgrown world reclaimed by nature. Scavenge the ruins for supplies, piece together what happened, and weigh every risk. Daylight keeps you safe, but it never lasts.

Rescue

Survivors are scattered and scared. Track them down, earn their trust, and bring them home. Each one arrives with their own skills, history, and reasons to stay.

Build

Dig in and design your shelter room by room, planned from above like a dollhouse. Power, water, food, defences and morale all hang on how well you build and expand.

Survive

When the sun goes down, the Altered come. Hold the line, ration what little you have, and make the hard calls. Every night you survive is another story your shelter carries.

Rescue Survivors

They're out there. Find them. Bring them home.

Build Your Shelter

Create a safe place beneath the ruins.

Care For Your People

Keep them fed. Keep them hopeful.

Survive The Night

The Altered come out when the sun goes down.

Keep The Power On

Wire up generators and salvage fuel. Lose power and the lights, doors and pumps die with it.

Find Clean Water

Pump, filter and ration clean water. Thirst kills as quietly as the Altered.

Your Story

Every decision you make shapes the future of your shelter and the people in it.

Chapter 01 · The World

The Last Place
Standing

300 years after the Sonic War, the surface is silent. The Altered hunt by night. The Settlers hide by day. You wake up alone in a concrete room with a word scratched on the wall: KORE. You don't remember why.

Chapter 02 · The Rescue

Track
The Signal

Survivors broadcast for help across Ashgate. Race them to the surface before nightfall. Bring them home. Watch them become Settlers. Every rescue grows the family.

Chapter 03 · The Night

Hold
The Line

When the lights flicker, you'll know. Power the generator. Lock the doors. Trust your Settlers. The night doesn't last forever, but morning comes at a cost.
