Frost Train

One factory train, one boiler, a frozen continent. Every crate you salvage costs heat, and when the boiler freezes the run is over.

Frost Train is a 3D roguelite. At each stop the train halts beside a buried vault. You walk a cable-tethered crab-mech out over the snow, cut the vault door open and haul the crate home while the boiler cools. The cable only reaches so far: relay it, or unclip and run on battery.

Between stops you pick the route on the map, weighing distance, loot and the heat the next leg will cost, and build out the train with what you salvaged: smelter liners, insulation, battery racks, heat exchangers, cable reels, extra flatcars.

Every stop is a different place. Rail yards with water towers and gantries, open steppe under power lines, frozen lakes, glacier ridges and blue ice, each with its own weather and hazards. At the last stop a storm front closes in.

• Runs of 30 to 40 minutes, a new route every time
• Vault bunkers, wreck trains, radar domes and signal masts to salvage
• Deep snow, damaged cable, cold snaps and blizzards
• Unlocks that carry over to your next run
• A daily run: the same map for everyone, with a board
