In Cold Engine you are assigned to a train, a debt, and a quota. Choose routes, deliver cargo, manage heat and energy, and keep moving through a frozen system that values the process more than the operator. 

Accept contracts, choose routes, and transport sealed cargo between isolated stations.

Each delivery pays toward your debt — if enough of the cargo survives the trip.

The train is your shelter, your workplace, and your life support.

Keep the engine running, the temperature stable, and enough power left to reach the next station.

A stronger train means longer routes, heavier cargo, and fewer excuses.

Invest carefully: repairs, upgrades, and quota payments all compete for the same money.

Complete the delivery and move forward. Debt can shrink, quotas return, and the next route is already waiting.
