The world is gone. The Frostfall left humanity scattered, buried beneath ice and snow.
Behind the wheel of your Old Grizzly, accompanied only by T3DDY, a small drone, and the voices of your fellow survivors crackling through the radio, you venture into the frozen wasteland.
Your only chance may be Sunnyland, a mysterious refuge where the cold is said to be less severe. First, you'll have to repair the old train that will take you all there.

Out there, everything you need is buried somewhere beneath the ice.
Take Old Grizzly into abandoned cities, frozen lakes, and mountain forests. Scavenge what you can, turn it into new tools - grappling hooks, ice tires, nitrogen guns - and push further into the unknown.
But the cold doesn't wait. Night falls. Storms roll in. Supplies run low. How far will you go before turning back?

The world may be frozen. But not everything is.
An old AI still controls machines scattered across the wasteland. Hack them. Disable them. Exploit their glitches. And as you dig deeper, you may start to wonder: what's the AI real purpose?

You can't stay out there forever.
Back at the Firewall, a safe haven from the harsh weather and threats of the wasteland, the survivors need food, medicine, and heat, while the train needs to be repaired. Work with Pops, Nova, and Sak to keep the camp alive, improve your gear, and prepare for the next expedition.
Everyone is waiting for you to come back.

Humanity's last hope may be in your hands.
