Scorching Engines

After an asteroid plunges Earth into a permanent winter the survival of Humanity's Colony depends on the transportation of a powerful heatcore. 

Drive a giant experimental vehicle across the frozen wasteland while being protected from the cold by the powerful heatcore inside the vehicle. Gather resources, fight off raiders, and reclaim the vehicle parts the raiders stole. 

Exploring the world you need to harvest resources to keep the engine running, craft ammunition for your guns, and find upgrades for the vehicle.

In this hostile world you will need to protect both yourself and the vehicle against storms, the cold, and raiders that want the heatcore and vehicle for themselves.
Defend it by using turrets onboard your vehicle, guns, or by avoiding the raiders altogether
