The moon is shattered. The world has frozen.

Take command of a nomadic train city hurtling through a war-ravaged frozen wasteland. In this survival city builder on rails, gather survivors, scavenge resources, and do whatever it takes to keep the engine running and stay ahead of the frost.

The wars that followed plunged humanity into endless winter. Your last hope is the Frostliner, a colossal train built to survive the cold and carry survivors across a frozen Earth. Scattered pockets of humanity cling to life in small, isolated communities, and most stops you make will offer the chance to bring new people aboard.

On its steel tracks, you will carve a path across a frozen Earth, adapting your mobile city to meet the needs of those who call it home. Explore a handcrafted world and follow a gripping, linear narrative as you chase warmth, safety, and the faint promise of a future at the end of the line. Somewhere out there lies the key to a lasting refuge, hidden away and waiting to be found.

Transform your train into a thriving city on rails. Use the Factory to build new carriages, then fill them with essential facilities to keep your passengers alive, produce vital resources, and research breakthrough technologies. Place your buildings wisely, as facilities gain powerful adjacency bonuses that make your Frostliner stronger and more efficient the longer it grows.

The engine hungers. To keep moving, you must stop and scavenge for fuel, supplies, and survivors. But when the train stops, the heat dies, leaving you with only your limited reserve batteries to fend off the killing frost. Every halt is a race against time, and every stop is a choice between safety and risk.

The cold is not your only enemy. Other threats stalk the frozen rails. Arm your Frostliner with defensive weaponry to fight them off, or push the engine to its limits and outrun them before they close in.

“I’m blown away by the attention and support Frostliner has received. I never imagined I’d reach 10,000 wishlists so quickly! Seeing how much people believe in the game has inspired me to start exploring bringing other developers on board. I want to make Frostliner the best it can possibly be.” - Nathan Gane, Lead Developer
