| Update | Date | Excerpt / source |
|---|---|---|
| Update for Unity security vulnerability (v1.24) | 2025-10-05 | As already reported in the news, security vulnerability has been discovered in Unity game engine. Since this game also uses Unity, we have replaced the objects with clean-built ones using security-patched Unity (2022.3.62f2). Additionally, we performed the following maintenance to reduce file size and mitigate future security risks. Removal of unused Unity packages Update to latest version of Steam API (Steamworks.NET) |
| Participating in Steam Turn-Based RPG Fest 2024! | 2024-09-30 | This game "Underground Defense Force" (UDF) is participating in Turn-Based RPG Fest! We hope you'll take this opportunity to pick up if you are interested! https://store.steampowered.com/app/2603860 |
| English translation for story texts (v1.22 => v1.23) | 2024-08-31 | Following the previous update (see below), proceeded to translate the untranslated texts into English. https://store.steampowered.com/news/app/2603860/view/4599951478185432388 With this update, the story (in message window) and end roll are now available in English. The remaining is the summary text for weapons, armors, and missions. However, due to the volume of text, the number of characters limit of the UI, and the Japanese-unique content that is difficult to translate (*), we may not be able to proceed the translation soon. (*) For example, "Love" in Japanese language (= Kanji letter "愛") and "Mana" are read the same in Japanese, as they |
| Some remaining English translation (v1.21 => v1.22) | 2024-08-28 | Some untranslated texts were translated into English. (Message windows in Mission 20, 27, 34, 37, 38.) On the next update, mission 39, 40, and end rolls will be translated. Overview texts for equipments (weapons/armors) and missions will be further later. Please note that due to the fact that this is an individual development indie game, I cannot guarantee that I will actually be able to proceed with the English translation, including determining the specific schedule. However, I will make my best efforts. Thank you for your understanding. |
| Released a SLG bundle in collaboration with Flying Panjandrum! | 2024-08-13 | In collaboration with Flying Panjandrum, whose motto is to create "unserious but serious" games, we have released a SLG bundle! This unserious but serious title, "Underground Defense Force", is also included in this bundle, giving a 20% discount on the total of the three works. Even if you already own one or several of the titles, you can complete remaining titles for 20% OFF the total price of the unowned titles only, so those interested are encouraged to take advantage of this bundle! https://store.steampowered.com/bundle/43990 Note: Total amount displayed before adding to cart The total amount of this bundle displayed on Steam may NOT be s |
| Added "Open Save Folder" menu (v1.2 => v1.21) | 2024-07-23 | Added "Open Save Folder" menu to Option screen. If time permits, we would like to support multiple saved data files in a future update. For now, we have tentatively added the menu to open the location of the folder where the saved data file is stored on the Option screen using Explorer or other programs. Please note that, as the note on the screen indicates, if you do not temporarily turn OFF the Steam Cloud setting, your deleted or overwritten save files will be restored by Steam Client. (You can turn ON or OFF the Steam Cloud settings by opening "Properties ..." from the right-click menu of this game on your Steam Client.) |
| New Difficulty Level "IMPOSSIBLE" formal released! | 2024-07-17 | A new difficulty level "IMPOSSIBLE" which can only be challenged by players who have completed INFERNO, has been released formally and now available as v1.2! If you have already played IMPOSSIBLE level in beta branch, as described in previous announcement (below), please change the "Beta Participate" field back to "None". https://store.steampowered.com/news/app/2603860/view/4220517501581638441 Note that, I, the author of this game, have confirmed that all the missions can be accomplished by myself, so the game balance is NOT unchanged from the previous beta version (v1.2beta2). Some of the missions may have become so unreasonable that they ca |
| IMPOSSIBLE (beta) is now even more difficult! (v1.2beta2) | 2024-07-15 | This update is to the beta branch of IMPOSSIBLE difficulty, as described in the previous announcement (below). https://store.steampowered.com/news/app/2603860/view/4220517501581638441 Changes (v1.2beta => v1.2beta2) The IMPOSSIBLE game balance has become even more difficult and formidable! Changed IMPOSSIBLE Damage Deal Variance from +/- 20% to +/- 5%. Increased all IMPOSSIBLE enemies' Health except boss monsters. List of IMPOSSIBLE enemies' Health (from old to new) Ant 2184 => 2974 Spider 2496 => 3411 Hornet 1456 => 1892 Cockroach 2704 => 3411 Moth 2704 => 5699 Woollybear 3120 => 3785 Caterpillar 2704 => 3785 Firefly 3120 => 3785 Burrow 4784 |
| New Difficulty Level "IMPOSSIBLE" has been pre-released in beta branch! | 2024-07-05 | A new difficulty level "IMPOSSIBLE" which can only be challenged by players who have completed INFERNO, will be officially released at the next update. Currently, in the process of adjusting the balance, and not fully tested, but decided to release it tentatively as a beta branch (* see below) for those who want to try it out even if the game is unstable. I, the author of this game, am adjusting the game balance during test play, so there is a possibility that the game will become more difficult or easier before formal release. Please understand it. If you have played this beta version and have any comments/suggestions, I'd appreciate your fe |
| Participating in Steam Summer Sale! | 2024-06-27 | Yakuentei's indie games (including this game) are participating in Steam Summer Sale! We hope you'll take this opportunity to pick up if you are interested! https://store.steampowered.com/app/2603860 https://store.steampowered.com/app/2166220 https://store.steampowered.com/app/2083960 Note that, due to Steam rules, we were unable to participate in the Summer Sale for the DLC of "Students of Light Bonds" because one month has not passed since the launch discount. We think we'd like to participate from the next sale, so please stay tuned! https://store.steampowered.com/app/3001140 |
| A small change of NPC's AI algorithm (v1.12 => v1.13) | 2024-06-08 | Modified the NPC's AI algorithm so that friendly-fireable weapons/magics are used even when there are only ally units around. This update only affects the AI algorithm of the NPC Mage Infantly who uses the suicide spell "Manner Mode α" in the Mission 13 "Recital of Mana". Until v1.12, it was possible to stop him from using "Manner Mode α" by defeating all insects around him. From v1.13, even if there are only allies around him (even if it only hits himself!!), he has become an extremely dangerous presence that will "self-destruct" without any questions asked! "I'M GOING TO DIE ANYWAY! YOU ARE ALL GOING WITH ME!" "I'M NOT AFRAID! I'VE GOT NOTH |
| Added "READY" blink (v1.11 => v1.12) | 2024-06-04 | Added "READY" blink notifications before starting each wave when "Viewed Event" setting is "View" (including when the mission has not been accomplished). This feature was made to prevent accidental misfiring of weapons with friendly fire (e.g., "Blast/Multi-Cast" magics) while repeatedly clicking the mouse to skip the message window. Unfortunately, the request to eliminate friendly fire itself is "rejected". Because, even in the homaged original game (= "Ea*th Defense Force" series), it is a "promise" that "Rocket Launcher", "Thunder Bow", etc. will hit friendly NPCs directly, and you yourself will be killed by a single hit!! Separate post: S |
| Bug Fix (v1.1 => v1.11) | 2024-05-17 | Fixed a bug that caused the final mission to be treated as a win, even if all the player characters were wiped out. Found a very frivolous bug. My apologies ... (Since it is obviously a "player advantage" bug, so I may be offended by fixing it ...) The version under development (at the time of closed test play) was working correctly, but somehow I made a strange modification to the victory conditions, causing it to "degradation". My apologies. |
| Added the blur option for "cockroaches" | 2024-05-15 | We have completed the implementation of "Blur Cockroaches" as announced in yesterday's news! https://store.steampowered.com/news/app/2603860/view/4209254069393094342 If you don't want to see cockroaches as they are, let's try switching the "Blur Cockroaches" to "ON" in the "UDF HQ" menu! |
| Planning to add the blur option for "cockroaches" | 2024-05-14 | I, the author of this game, am happy to see various reactions on SNS such as X (Twitter)! Now, we have received comments from some Japanese users that it is painful to see the "cockroaches", or at least an option to apply blur to them, or etc. Therefore, we are now planning to add the blur option like as following screenshot. If possible, it may be more flexible to blur other insects as well, but we believe there are many people (especially Japanese) who "just do not like cockroaches", so we will focus on supporting "cockroaches only" and will work to provide an update as soon as possible. Thank you! |
