EARLY ACCESS DLC

THE LONG DARK: IRON ROAD is Early Access DLC for THE LONG DARK’s Survival Mode. It expands the base Survival Mode with a whole new island, new gameplay systems, and a full range of new content for THE LONG DARK. As an Early Access product, the DLC will launch with a partial roster of the full intended content for the DLC, which will be released over time as it is built alongside the player community.

For a full breakdown of features and content added in the DLC, visit the IRON ROAD EARLY ACCESS ROADMAP.

AN ISLAND LOST TO TIME

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.

AN OLD MYSTERY UNFOLDS

A century ago, a rich industrialist named Hamish McLeod harnessed the unique properties of Cauldron Island with a plan for economic domination through whale-oil powered technology. But this history was erased, and the dark truth about how things went wrong has been hidden in the past. Until now.

Get to Cauldron Island and uncover the truth. Follow the path laid by Alice McLeod, his great-granddaughter, who came here to crack the mystery of her family legacy. 

Because uncovering the mystery of Cauldron Island is core to your survival in this new Aurora-blasted world. And the journey Alice started is yours to complete. 

The Prototype Train

Standing at the heart of McLeod’s planned industrial revolution, the Prototype Train has been hidden for a hundred years. Find it, bring it back to life, and use it to explore over 100 kms of track, deep into the dark heart of Cauldron Island to uncover the mystery of McLeod’s failed empire.

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.

Meanwhile, time has not been friendly to Cauldron Island’s abandoned railway infrastructure. You’ll have to contend with broken track, geothermal hazards, rock falls and avalanches, and the slumbering remnants of McLeod’s abandoned empire. You’ll need all your skill and perseverance to make it to the end of the track.

THE AURORA, EVOLVED

The deeper you travel along the spine of Cauldron Island, the more extreme the Aurora effects become. This is a preview of what’s to come in the post-WINTERMUTE Aurora-changed world. Alice was the first to document its effects, but you’ll ultimately be the one to explore and experience the heightened Aurora. And the train will be key to your survival.

THE “FULMAR” AUTOPILOT BOAT

Your connection to and from Great Bear Island. Travel isn’t free, and it favours the prepared. But the Fulmar makes it possible to bring useful gear and resources from Cauldron Island back to use on Great Bear Island in the Survival Mode Base Game. And when you’re ready to return to Cauldron Island, the Fulmar will be waiting in Desolation Point.

HISTORY, LEFT BEHIND

NEW SAFEHOUSE CUSTOMIZATION ITEMS

WORLD STRUCTURE

A flooded volcanic caldera formed an archipelago with five main islands, named after McLeod’s daughters: Anna, Stella, Freya, Morag, and Skye. Each island offers many points of interest, new regions, and tens of kilometers of abandoned railway line to explore.

When IRON ROAD launches, you’ll find the “Fulmar” Autopilot Boat can bring you from Desolation Point on Great Bear Island, to Port Remnant on Cauldron Island. From there, you’ll explore Anna Island and over 30 kilometres of railroad. Future Early Access updates will unlock the other islands.

EARLY ACCESS ROLLOUT

The IRON ROAD Survival Expansion will be updated continuously throughout the Early Access development phase. Smaller, more frequent updates will include ongoing bug fixing, tuning changes, and smaller features. Larger updates will include new parts of the world and more major mechanics. 

Many of the features and content are designed to be brought back to the Base Game and Great Bear Island, while some content -- such as the train itself -- is designed to work on Cauldron Island only.

The full IRON ROAD experience will be developed with player feedback in mind, using the full benefit of the Early Access development model to ensure that core gameplay, game balance, and tuning are aligned with player expectations.

MISSIONS AND NARRATIVE

Following the structure introduced in TALES FROM THE FAR TERRITORY, IRON ROAD will feature a series of audio collectibles and light narrative missions that provide objectives and motivate your journey across the entirety of Cauldron Island. These missions and narrative materials will be integrated directly into the game’s survival sandbox.

DEVELOPMENT APPROACH

Our plan is to release regular bug and quality of life improvements throughout IRON ROAD’s Early Access development, balancing the development team’s efforts by alternating between Small and Large updates throughout the campaign.

We are aiming for monthly Small updates and quarterly Large updates, as well as regular hotfixes to address bugs and balance changes in between.

For reference, a Small Update would include more isolated features and content, like new foods, clothing items, etc. A Large Update would include (for example) major new Train systems, or a new Island with associated Points of Interest and narratives.

BECOME PART OF THE JOURNEY!

Early Access is about involving, you, the player in the process of refining the game experience. Please share your feedback, comments, and bug reports in our dedicated IRON ROAD feedback portals.

EARLY ACCESS DISCLAIMER

Hinterland has been involved with Early Access-style development since launching THE LONG DARK in 2014, so we believe our players can purchase IRON ROAD with the confidence that we will deliver a high-quality experience, and live up to our obligations.

That said, due to the nature of game development, and because the team is building IRON ROAD guided by community feedback, it is possible that some planned Roadmap items might change over the course of the Early Access development process. In cases where the development team makes a change, the item will be replaced by an alternative of relatively equal “value” in terms of development effort. Of course, “value” may be interpreted differently from player to player.

The Early Access Roadmap for IRON ROAD should be seen as an aspirational document, and is not a promise or guarantee. As per Steam’s disclaimer for Early Access products, if you do not like what you see in the current build, you should wait until IRON ROAD is complete. Hinterland would prefer that you have a product you are happy with rather than feeling disappointed.
