[Part 1/2]
Hi guys,

Today we're releasing our last major free content update for Underrail. It's been just a bit over six years since the full release of the base game, and I think that's a nice and round number to rest at. After this we're going to transition to working at about 95% of our collective capacity on our next project known under codename Infusion. You can see what's this project about and follow its development here: We should start posting dev logs there more regularly soon.

However, this does not mean that we're completely done with this game. We intend to support it as long as we exist as a company and also periodically release small content updates which will mostly feature mechanical tweaks, as well new items and abilities. We have quite a robust system for creating interesting items at this point, which we intend to use to further extend Underrail's playstyle catalogue so to speak.

Also we have some bigger features planned for the future, such as better adapting the game's UI and controls to Steam Deck, creating tools for community translation projects, potentially porting the game to other platforms, and more.

Another distinct possibility is an additon of a small paid DLC for Underrail, as there are some substantial gameplay mechanics that we initially planned to add in the second DLC (following Expedition), but were left in a state of limbo after we decided to move onto Infusion instead.

Exactly when any of these things will come about, I do not know. They will mostly require me to spend my programming time on them, which I will not have much to spare as Infusion is going to occupy most of it in the coming years. So don't expect rapid progress in any of the things mentioned above.

Now, without further ado, here's the list of changes and additions that come with this update, minus the secret stuff, of course:

• Implemented, new slightly visually touched up, UI that is available in 3 sizes; classic UI still available
• The game will now automatically be zoomed on higher resolutions (which can then be changed through manual zooming if it's enabled)
• Introduced a brand new Core City questline as an alternative to joining an oligarch
• Improved nearly all unique and some rare weapons and armor - go check them out
• You can refurbish your old world firearms at one of the firearm enthusiasts
• Characters can now save up to 10 action points at the end of their turn and add those to their next turn
• Base ability values are no longer capped at 20, but instead the maximum bonus on top of the base value that you can accumulate is 10

• Implemented borderless windowed display mode
• Item's special abilities/attacks will now have icon in the item's tooltip next to the description
• Fixed character's speech bubble and health bar offsets when zoomed in
• Zooming step changed to 25% (down from 50%)
• Added an option to follow the player character (default hotkey: F3). This is kind of an experimental feature, so be sure to let me know if you discover any bugs

• Opportunist - description now specifies it only works against living targets
• Pummel - will now list the action point cost
• Fend - Base action point cost changed to 60% of normal attack ap cost (down from 100%)

• Fend: Action Point Cost - Ap cost reduction per point changed to 8% (down from 10%)

• Increased t-boss health on dominating difficulty, and his damage resistance on all difficulties
• Expanded upon Motion and Motioners; this drug is now both better and worse
• You can now bring Gorsky high-quality energy shields from other sources as an alternative to raiding Port Zenith
• Added an agility check that allows you to climb up and down between the Caerus Residential Block square and SW building second floor
• Added fireplaces to certain locations in Deep Caverns
• Added a hacking check to Cytosine Outpost storeroom
• Added more hydraulic fluid canisters to Deep Caverns
• Certain gate components can now be found at multiple locations in Deep Caverns
• You can now use electronics skill to optimize Arke power plant turbine output for more total power
• A certain important encounter with the Faceless will now feature some of them having their infusions active from the start (only on Dominating difficulty)
• Added an extra Thought Control check to the DC mindreading that allows the player to conceal his mischievous behavior
• You can now bring super steel refining data to Bernard in order to improve the quality of super steel plates; also raised the max quality from 160 to 180 for players who have Expedition installed
• Leonie will now offer the Infused Leather blueprint as soon as you show her you have super steel plates (currently you have to do the melting process with Bernard first)
• You can turn metal scraps into low-quality steel plates at Leonie's
• Added more ways to learn about a certain Foundry arms merchant
• Added more entries to the super secret organization database, and placed some of the existing ones behind higher access levels
• Added more options to save Maura
• You can now borrow (or "borrow") AK from Kokoschka
• Becket now also offers psi inhalants alongside psi boosters when giving you your equipment package
• Added Underrail Express tickets which can be pickpocketed from NPCs and used for a single ride
• New models and portraits for Jon the Beautiful, Sergio the Wizard, and some super secret folks
• New random events, some of them seasonal, and some related to the player's house
• Introduced Jookhela's drawing skills to the world
• Increased requirements for achieving Brutalizer/Brutalette gladiator nicknames, so they shouldn't be so predominant now
• The Black Crawler now drops an oddity item when killed
• New entries in the Institute of Tchort library, some of which contain blueprints and will require a special card
• New skill checks for Octavia, Vuk and Kiro that will unlock certain items for trading
• [Expedition] Naval mines will now be heard detonating in the distance when someone attacks the camp
• [Expedition] Added ways to break yourself free from a certain man's mechanical grasp
• [Expedition] Added certain dialog options to Doc Savage and Marcus that were only available through navcom
