Frostliner: Build a City on Rails to Survive the End of the World

In Frostliner, an upcoming survival city builder with a unique twist, you’re not hunkering down in some sheltered base—you’re leading a mobile train city across a brutal, frozen wasteland. And the only rule? Keep moving, or die trying.

A Train Is Your Last Hope

Set decades after a cataclysmic event shattered the moon and plunged the planet into a deadly deep freeze, Frostliner puts you in charge of a colossal locomotive engineered for survival. Your train—the Frostliner—is a moving city, a last refuge for humanity, and the only thing standing between your people and the icy void.

You’ll scavenge abandoned settlements, rescue survivors, and manage a fragile ecosystem of life onboard. But once that train stops, the clock starts ticking—and the cold doesn’t forgive.

Expand and Optimize

Your train isn’t just a machine—it’s a modular lifeline. Build new carriages using your onboard factory, each housing different facilities: power generators, living quarters, research labs, and more. Placement matters—adjacency bonuses mean smart layouts will reward you with increased efficiency as your train grows longer and more complex.

But growth comes with challenges. As your population rises, so do their demands. Can you keep up?

Risk Every Stop

You’ll need to make frequent stops to refuel and resupply, but every halt is dangerous. While stopped, your train no longer generates power—leaving you reliant on backup batteries to keep the heaters running. Fail to restart the engine in time, and your passengers could freeze before your eyes.

Resources are tight. Every decision is high stakes. And every stop could be your last.

Protect the Line

The cold isn’t the only threat out there. Desperate survivors and twisted factions want what you have. Equip your train with defensive weapons or pour everything into speed upgrades to outrun your enemies. When diplomacy isn’t an option, survival may demand sacrifice—like using the infamous corpse furnace to convert the dead into precious fuel.

Morality isn’t black and white on the frozen rails.

Key Features of Frostliner:

• Construct and expand the Frostliner, your massive mobile train-city.

• Use adjacency bonuses to optimize productivity as your train grows.

• Manage a survival loop of scavenging, fueling, and decision-making.

• Unlock and research grim technologies to keep your people alive—by any means necessary.

• Stop to recruit survivors, collect resources, and clear debris—but every moment offline drains power.

• Defend against raiders or outrun them—fight or flight is always on the table.

Frostliner challenges you to survive on the move in a world that’s frozen to the core. Will your engine make it to the end of the line—or will the frost claim everything?
