Elite Soldiers have been remov…
- ver. 0.9 Beta – Added Quest System & External Factions - 13 June 2026
ver. 0.8 added the ocean system, and ver. 0.9 added quests and external factions. Below are the updates made during that period. The quest system in ver. 0.9 is currently available only in the beta version. For Zundamon Castle, the remaining plans are to make some adjustments to diplomacy features and implement mining-related systems before releasing the full version of the game. 【Major Additions】 Implemented seawater (when starting a new game on the Japan terrain map, seawater and freshwater are now distinguished). Unlike freshwater, seawater cannot be used for rice paddies or water collection. Fishing huts and ports built on seawater receive ocean bonuses.

- Minor Feature Additions & Bug Fixes - 9 February 2026
【Feature Additions & Specification Adjustments】 Idle Zundamon will now communicate with nearby labor Zundamon.

Added level indicators to the unit details panel. 【Bug Fixes】 Fixed a bug where roads could disappear when loading. Fixed a bug where roads could disappear due to snow.

- ver0.701 Major Update: Implementation of Real-World–Based Soils! - 2 February 2026
【Content Additions & Specification Changes】 Added around 50 types of soil and rock blocks. Fertility has been assigned to each soil type. Set fertility impact values for each crop. For example, soybeans are less affected by fertility, while rice is more strongly affected, creating differences between crops. Added millet, barnyard millet, buckwheat, and sweet potatoes as crops (can be cultivated via domestic technologies). Previously, in-game temperatures were adjusted to about −5°C compared to modern temperatures to match the Sengoku period, but they have now been revised to be slightly warmer. With the introduction of fertility, initial food amounts have been increased on Normal and lower difficulties so that players do not struggle to get started even on poor land. Reduced the damage dealt to buildings by enemy ranged units other than cannon units to one quarter. In addition, ranged u…
- β Update: Realistic Soil and Rock, Bug Fixes, and Specification Changes - 18 January 2026
A test implementation has been added where ground blocks change when creating a new map, based on real-world japan rock and soil data. Originally, this feature was planned to be implemented after further adjustments, but since major bugs (load errors, units getting stuck at ports, and freezes after combat) occurred in the previous version, the soil update has been included alongside the fixes for those issues. Balance and production-related specifications will be adjusted as needed over time. 【Feature Additions & Specification Adjustments】 Added more than a dozen new block types. Based to some extent on real-world rocks and soils, Japanese-style terrain can now be generated (test feature) Removed the feature that skipped rendering distant units (due to poor reception and frequent recognition as a bug) Changed the specification for generating objects on top of blocks, such as roads and s…

- Beta Update: Auto Building Evacuation, Digging Visibility Improved - 28 December 2025
【New Features / Specification Changes】 Added an automatic evacuation feature from buildings. Added the ability to configure troops from the soldier control button. Added a feature that allows selecting all soldiers inside a building with Ctrl+A while the building panel is open.

- ver.0.637 – Implementation of “High Bridges” “Descending” and “Terraced Paddies - 19 December 2025
Due to the trade-off with keeping processing lightweight, implementing a “descending” feature from high places had been difficult, but it has now been officially implemented. In addition, movement processing has become more accurate than before, so even in situations where a large number of enemies appear and frames drop slightly, enemies now move along their paths instead of warping. 【New Content / Specification Changes】 Added high bridges, including vermilion-lacquered bridges Implemented a descending feature (previously, when moving from a high place to a lower place, units would warp; they now properly climb down walls) Added the “Terraced Paddies” technology to technologies Added a button to dismiss multiple soldiers at once Unit movement is now processed more accurately, preventing enemy warping even when FPS drops Changed specifications so that voice language can be switched inde…
- Beta Update: Water Building Fixes, Climb/Descend Tweaks, Movement Improvements - 11 December 2025
Added a feature where unit climbing speed decreases in proportion to the height they are climbing (the farther from the ground, the slower they climb). Adjusted pathfinding so that higher elevations are more strongly avoided (height is now treated as n² instead of n). Added a “descending” feature so units no longer instantly warp when moving from high to low areas. Since the descending feature increases the difficulty of economy management, enemy parameters on Normal difficulty and above have been adjusted downward. Added Cook Zundamon. All cooking-related tasks are now assigned to Cook Zundamon. Enhanced the movement system so unit movement remains accurate even under frame drops. Added an option to change this per-frame limit. (Because the number of pathfinding calculations per frame has an upper limit, workers may stop when towns grow large and they must wait for pathfinding. Setting…
- Beta Update: Bug fixes in the beta version and visual adjustments to the bridge - 8 December 2025
【Bug Fixes】 Fixed an issue in the beta version where the costs of technologies and the remaining number of workers for distribution were no longer visible. Fixed an issue in the beta version where, if there were not enough farmers when loading a save, a “temperature too low” icon would incorrectly appear over fields and rice paddies. Fixed an issue in the beta version where units in the distance were omitted from rendering and became invisible. 【Content Additions & Balance Adjustments】 Slightly optimized performance when large numbers of enemies appear. Adjusted the volume of sword-slash sound effects. Adjusted the position of the vermilion-lacquered bridge’s girders to improve its appearance (the standard bridge will be adjusted in a future update as well).
- Beta Update: Added High Bridges, Bug Fixes, and Cannon Balancing - 7 December 2025
Added tall bridges and vermilion-lacquered bridges. Changed the specifications so that the voice language can be switched independently from the UI language. Adjusted high-difficulty enemy appearance lines so that if a samurai appears before an ashigaru, the event dialogue will use the samurai’s lines. Reduced the number of raids in which Samurai Cannons appear (as their frequent appearance in Endless Battles was troublesome). Lowered Samurai Cannon HP; slightly increased their attack power and attack speed. Fixed an issue where item quantity text could overlap adjacent icons. Updated specifications so that quantities of 100,000 or more are shown using “M”. Fixed an issue where the top item-count icons could be crushed when starting the game. Fixed an issue where, if loading data saved after evening on a turn when a battle will occur the next morning, units would move to the standby pos…

- Beta Update: English Voice Implementation, Bug Fixes, and Balance Adjustments - 15 November 2025
【Content Additions / Balance Adjustments】 Implemented English voice lines (some lines are currently quiet; volume will be adjusted for the official release). Changed the ninja mechanics. When a ninja appears, only soldiers’ line of sight is now used to determine the spawn location (the ninja starts from one of the outer-edge cells and moves up to within 9 tiles of a soldier before spawning). Slightly decreased the selling efficiency of the Rice Shop. In exchange, slightly increased the sale value of treasures from Stalls and Townhouses. Increased the rice required for constructing the Elite Hall (as rice tends to be oversupplied in-game, this change aims to slightly increase consumption). Adjusted Hard difficulty and above so that the level variance of normal raids is reduced. Slightly weakened enemy HP on Hard difficulty and above (taking into account the ninja mechanic changes. Since…
- ver0.58 Sushi & tea added! Worker meal effects and simple defense huts - 9 November 2025

- β Update: Added sushi, matcha, and green tea; adjusted cavalry balance - 30 October 2025
【Content Additions & Balance Adjustments】 Implemented tea- and sushi-related technologies and buildings. Labor Zundamon are now affected by food and drink: higher attack increases work speed but causes faster hunger, while higher HP reduces hunger rate. Added a feature that displays on the task list panel when farms stop functioning due to low temperature. When loading save data from versions below ver0.53, combat points are now treated as both “Standby Points” and “Battle Points.” Removed the restriction preventing cavalry from entering castles. Changed the soldier selection range (using the green sphere with the F key) so that it scales with zoom level—narrower when zoomed in and wider when zoomed out, instead of being a fixed size relative to the map. Increased the amount of wood dropped from trees by +1, as the use of wood for tea and cooking has increased. (In Zundamon Castle, wood…
