UltrakULL (ULTRAKILL Language Library) is a modification (mod) for ULTRAKILL that allows for modification of the game's text strings, effectively allowing for translation and localization into various languages.
This mod's primary purpose is to bridge the gap for localization and translation until ULTRAKILL receives official translations.

• Translates the entire game from English to any language
• Support for multiple languages
• JSON formatting of language files allows for easy-to-understand, simple-to-do modification of strings
• Change languages directly in-game without having to restart
• Languages are consistently developed and updated for a faithful localization and translation of the original game text
• Dubbing support allows for translated spoken dialogue
• Supports right-to-left languages such as Arabic and Persian
• Cyrillic character support for languages such as Russian, Ukrainian and Belarusian

UltrakULL and can be be obtained either through the Releases page (recommended), or via the UltrakULL Discord.

The only prerequisite is a Steam version of ULTRAKILL.
Demo, GOG.com and cracked versions are NOT supported.

UltrakULL is available as a ThunderStore mod.

Download and installation can be done automatically via the R2ModManager.

(Downloading the mod via R2ModManager will also automatically download and install the required BepInEx dependencies.)

Installing UltrakULL via GitHub is divided into 2 parts:

• Installing BepInEx, the modding framework
• Installing UltrakULL, the mod itself

• Download BepInEx 5.4.21 64-bit here.
• Extract the contents of BepInEx to where your ULTRAKILL install folder is located.
• Launch ULTRAKILL once so BepInEx can generate the required files and folders in the install folder. Quit the game once it has loaded to the main menu.

• Extract the contents of UltrakULL to your BepInEx folder. Overwrite any files if prompted.

• If the mod has loaded correctly, you will see a new "Languages" tab in the Options menu.
• From the Languages tab, you can browse available translations for the game by selecting the "Browse Languages Online" button. Additionally, language files that are locally installed in the mod folder will be detected and made available for selection any available language based on the language files UltrakULL has found, and will load them into the game.

If the mod does not appear to load or work correctly, or errors occur in-game, please open the BepInEx console.

Open your mod profile in R2ModManager, and go to Config Editor -> BepInEx.cfg -> Edit Config -> Scroll to "Logging". Set both options to True.

Navigate to BepInEx/config/BepInEx.cfg, and open it in any text editor of your choosing. Scroll down to Logging and set "UnityLogListening" and "LogConsoleToUnityLog" to True.

Restart the game after applying either steps for your use case.

Available languages may be directly downloaded for use in-game via the Languages tab in the options menu. This list is updated on a semi-regular basis as new languages are made available. (Last updated on patch 13b, the 10th of December 2023)

As is the case with most updates for other games, any and all updates and hotfixes to ULTRAKILL will almost certainly break mod functionality to some degree. Work to future-proof the mod as much as possible is done to minimise such occurrences, but if an update breaks the mod, it will be fixed as quickly as possible.

Language files are formatted in JSON. If it does not appear as available, it is either not formatted correctly or does not match the minimum version required by the mod.
To check if a file is formatted correctly, open JSONLint in your browser, copy and paste the contents of your file into the window and click on "Validate JSON".
If the file is not formatted correctly, JSONLint will report any errors. Errors can be forwarded to the UltrakULL Discord's troubleshooting channel for assistance.

A dedicated troubleshooting and support channel can be found at the UltrakULL Discord.

Indeed you can! Thanks to this mod, ULTRAKILL has already been translated into various foreign languages, including French, Brazilian Portugese, Traditional Chinese, with many other languages also in development at the time of release.
If you wish to contribute to, or begin work on a new or existing translation or language, feel free to stop by and inquire at the UltrakULL Discord.

No, this mod merely changes text in the game. It does not alter your saves in any way.

No, for the same reason as above. It does not alter any gameplay aspects that would give an unfair advantage in any way, and as such, will be safe to set Cybergrind highscores with. If for some reason your Cybergrind highscores are not being submitted, and you are sure they should be doing so, feel free to shoot a message on our Discord and I will take a look at it.

As of UltrakULL v1.1.0, dubbing support is available for speaking characters! To learn more about how to add your own lines, check the dubbing documentation.

I usually like to post updates and news about development in multiple places, including the UltrakULL Discord itself, the New Blood Discord, and my personal Twitter.

I cannot guarantee mod compatability with other mods. Mods that do not use the HUD message display functionality should work just fine though.

GitHub documentation coming in future. Until then, documentation on how to create your own language can be found in the UltrakULL Discord.

Build instructions coming in future.
