Version 1.50.39 introduces one of the largest progression expansions added to the underground side of Knights of Crystalis so far.
Three previously planned roadmap features have now been implemented as one connected progression loop:
69. Mine Expansion 70. Deepfolk City 71. Mining Expeditions
Rather than building three isolated systems, they now directly interact with each other.
The Mine was previously useful, but comparatively limited in scope.
With 1.50.39, it becomes the foundation of an entire secondary progression ecosystem.
Players now descend through increasingly valuable geological regions, extract new resources, develop Deepfolk City, improve underground infrastructure, and send autonomous crews into newly discovered shafts.
The basic progression loop is now:
Mine → Rare Ores → Deepfolk City → Infrastructure → Expeditions → Survey Progress → Deeper Mine Layers → Endgame Resources
Each part of the system strengthens the others.
The Mine has been significantly expanded.
It now features:
The Mine is no longer just a simple resource generator.
Different depth ranges now represent distinct progression stages, with increasingly valuable resources becoming available as the player develops their underground operation.
Some of the deepest layers also require sufficient survey progress from Mining Expeditions before they can be fully accessed.
Eight new underground ore types have been added.
These resources support the new systems directly while also feeding into existing crafting economies.
Deep mining can now contribute toward resources such as:
This gives long-term Mining progression meaningful connections to equipment development and Itemization 3.0.
Deepfolk City is now a fully developed secondary settlement.
This is not simply another shop or menu.
The city contains:
10 upgradeable districts
Each district can be upgraded through 5 levels, creating a total of 50 district progression stages.
City development influences:
Deepfolk City therefore acts as the central infrastructure layer for the entire underground economy.
Players gradually transform the settlement from a small underground outpost into a major Deepfolk city.
Resources gathered from Mining and Expeditions can be reinvested into the settlement.
Those upgrades then make Mining and Expeditions more effective.
This creates a persistent feedback loop where every underground activity contributes toward larger long-term development.
Deepfolk City also introduces its own:
The result is effectively a second major progression hub inside the game.
Mining Expeditions introduce a new autonomous exploration system.
Players can discover and survey underground shafts using permanent expedition crews.
The system currently contains:
Different shafts offer different opportunities and risks.
Deeper expeditions can uncover increasingly valuable materials and contribute toward unlocking additional underground progression.
Once established, Deep Crews can operate automatically.
Players do not need to manually control individual miners.
Instead, the focus is on strategic progression:
The system is designed to complement the game's broader offline-MMO simulation structure rather than turning Mining into a manual minigame.
Advanced underground progression allows expedition crews to be automatically dispatched.
Up to four crews can operate simultaneously once the necessary infrastructure has been developed.
This makes Mining Expeditions an additional long-term background progression system alongside the game's other automated activities.
Mine carts and Mining Expeditions continue progressing while the player is away.
Offline progression is therefore now significantly more important to the underground systems.
Returning players may find:
This reinforces the game's persistent-world simulation design.
Several new achievements have been added around the expansion.
They track milestones including:
These achievements provide additional long-term objectives for players who want to fully develop the underground progression tree.
A major goal of this update was ensuring the expansion did not become an isolated side activity.
The new underground economy interacts with existing progression through crafting and equipment resources.
Rare underground finds can contribute toward:
This allows players who invest heavily in Mining to gain advantages elsewhere without making underground progression mandatory for every build.
