A Ruined City,
The Last Base

— Days of surviving in a base among the ruins after The Great Collapse —

An unidentified Great Collapse brought the world to a standstill. In the heart of a ruined city, a single fortified shopping complex remained as the last safe zone.

Limited food and drinking water, flickering power, depleted medicine — and an unknown threat outside. You are one of the survivors who drifted into this base.

Some hold the base together, some quietly fall apart, and some never reveal what lies beneath. There is no predetermined storyline. Whoever you become involved with and wherever you go, the days at the base will unfold accordingly.

🤝 Their hearts begin with wariness.
A single act of kindness will never be enough to open them.
When you weather crises together and trust builds, their closed-off hearts find the courage to let someone in.

🎮 This kind of game

🏚️A ruined city, the last outpostSetting

An unidentified Great Collapse brought the city to a standstill. In the middle of the ruined streets, a fortified shopping complex remains as the last safe zone. Limited food and water, flickering power, depleted medicine — and an unknown threat lurking outside.

“This is the last safe zone left.”

🤝Hearts begin with warinessRelationships

Their feelings begin not with goodwill, but with wariness. A single pat on the shoulder will never be enough to open them up. Only after weathering crises together and building stubborn, enduring trust will their closed hearts finally make room for you.

“What’s outside and what’s within are never quite the same.”

🏗️Build up the outpostOutpost management

Raise the walls, reinforce the infirmary, farming area, and generator, and balance the resources that dwindle with every additional person. Send scouting teams outside to recover supplies and survivors, and hold back the threats drawing near.

“An outpost endures as much as you build it up.”

⚡Choices at every momentChoices · Emergencies

Will you force your way forward, or make room at your side? Every choice comes with something to gain and something to lose. Amid sudden raids, resource crises, and mysterious incidents that arrive without warning, your judgment will determine the outpost’s fate.

“A single word from you can change the outpost.”

Every day at the outpost is precarious. Resources dwindle, people waver, and the outside world is anything but quiet.

Even so, someone is preparing for tomorrow. In a broken world, can you survive alongside them?

Only you can protect the last outpost.
