The Long Dark: Iron Road, the new survival expansion for The Long Dark, is now available in Early Access for Linux on Steam.

The Long Dark is a survival game set in an icy, post-apocalyptic wilderness where you fight cold, hunger and wildlife to stay alive. In Iron Road you travel to Cauldron Island, restore a century-old train and follow 100+ km of railway to uncover a dark secret.

The price is €24.49 (currently 10% off at launch, so €22.04).

Welcome to Cauldron Island. Lost to history, hiding a mystery. A vast northern chain of islands with 100km+ of railway winding its way across the craggy and desolate landscape, and the abandoned remnants of a once-thriving whaling industry there for you to discover.

Restore and activate a century-old train to travel deep along this forgotten caldera to uncover a dark secret. What you discover in the end will change how you survive in this Aurora-bathed world, forever.

Part transportation, part mobile shelter, the Prototype Train is the key to unlocking the mystery of the past that could help open a door to a new future. Keep the train running, improve it, protect it. Because once you cross the threshold, it’s the only way you are getting back home.

Over the course of Early Access, IRON ROAD will add new tools, items, and gameplay systems including the Portable Oil Heater, the Wax Cylinder Player, Harpoon, along with new clothing items, new foods, new wildlife, and a full range of Safehouse Customization items that can be brought back to Great Bear Island.
