What’s New

In a nutshell, the Threat update is all about making the High wilderness feel like a more dangerous place. It is a more dangerous place. Be prepared to defend yourself. Be prepared to die, frequently. You are welcome.

Hazardous Discoveries

Various transient discoveries across the High Wilderness are now Hazardous Discoveries, that is they have a chance to give you a nasty surprise when you interact with them. This is generally in the form of spawning a beastie who will be rather displeased to see you (their sudden appearance may give you a bit of a shock, but we’ll be adding a more subtle spawn animation in the future).

Some discoveries (Vitrified Structures, Curators Eggs and Grim Inscriptions) now have a halo effect similar to Spectacles where Terror will be applied when you get too close. Others like Wefts of Unravelled Time force interaction when you approach. Sail carefully!


Weather is a special type of Hazardous Discovery that randomly spawns throughout the High Wilderness (there are many spawn points in the Reach but only a few in Albion at present. We will be implementing additional weather spawn zones in a future update). All weather exhibits a physical force on locomotives along with other effects, some negative others beneficial.

  • The Peacock Wind will increase your rate of Terror gain but also replenish your current barrel of supplies up to 100%.
  • The Candlewind will increase your rate of supply consumption. Ensure you have enough sustenance before daring to cross it.
  • The Storm-that-Speaks is an interactable discovery. If you can cope with the Terror gain and Hull damage on your journey to the eye of the storm, then perhaps you may speak to it.

The Diffident Bat finally has some company. This update sees the release of an additional three scouts, the Star-Smitten Bat, the Intrepid Cavy and the Ratronaut. For Kickstarter backers there is also the Cyclopean Owl. These are not just pretty pets, but useful lookouts each with varying abilities. There are three attributes by which scouts can be ranked:

  • Bravery. Scouts are either Cautious and search for things nearby (Diffident Bat, Cyclopean Owl) or Bold and have a longer range.
  • Curiosity. Scouts can be Diffident and only report a single find (Diffident Bat, Star-Smitten Bat, Intrepid Cavy), or they can be Inquisitive and spot up to three things of interest.
  • Acuity. Finally Scouts may be Oblivious and simply mark locations on your chart (Diffident Bat, Star-Smitten Bat, The Ratronaut), or they may be Discerning and will categorise their findings with unique icons.

The helpful critters can be acquired from a very special merchant who you’ll encounter at New Winchester. This trader will appear after roughly a month of in-game time on a new account and will have already set up shop on existing saves, so it’s worth a detour to take a look at his wares. Be warned though, the merchant is a traveller and once you’ve poked around his shop he will move on. Fortunately he will always leave a clue as to where he intends to visit next (after a number of stops he will move on to Eleutheria so ensure you do not squander your opportunities to purchase new scouts).


Agents now provide visual feedback when they are provoked. A crescent will be seen around your locomotive indicating the direction of the agent and their hostility towards you. The colour will change from white to red as an agent’s wrath builds and if it decides to attack the crescent will pulse deep red before vanishing. Some agents have bespoke animations, like Scrive-Spinters which emit a red glow of rage when they decide to hunt you down. Other agents will be updated with similar effects in due course.

Some beasties like the Scrive-Spinster and Enduring Dreadnought now have damage indicators. Dreadnoughts will start smoking when they reach 50% health and will catch fire around 25%. Scrive-Spinsters have a similar effect where they start to ooze yellow particles as they take damage. Again we’ll be applying similar effects to other beasties throughout the High Wilderness in future updates.

There are now bunch of new ways for you to accrue wrath from various enemies. Some agents in the Reach will be friendly or hostile towards you depending on your allegiance in the Winchester War. Some will become angry when you are running errands for their enemies in the form of Prospects and Bargains. Other agents, like the territorial Chorsiter Bees, will take issue with you when you are carrying certain items. Approaching them may raise their hackles and while they'll check you out they will generally leave you alone. If you're carrying Nectar however, well, just remember our advice. Don't antagonise the bees!
