There are 12 supported languages in Outer Wilds: english, spanish_la, german, french, italian, polish, portuguese_br, japanese, russian, chinese_simple, korean, and turkish.

All translations must go in a folder in the root directory called “translations”.

In this folder you can put json files with the name of the language you want to translate for. Inside this file just follow the translation schema.

Here’s an example, for russian.json:

"$schema": "",
"DialogueDictionary": {
"Fred": "Фред",
"You looking at something?": "Ты что-то искал?",
"Aren't you guys all supposed to be dead?": "А разве номаи не вымерли?",
"ShipLogDictionary": {
"Unexpected guests": "Незванные гости",
"Visitors": "Гости",
"When I went to sleep by the campfire only Slate was here, who are these characters?": "Когда я ложился спать у костра здесь был только Сланец. Кто все остальные?",
"I met a talking jellyfish. His name is Geswaldo!": "Я встретил говорящую медузу. Его зовут Гесвальдо!"

  • Not supported extracting UIDictionary and AchievementTranslations

    • It is difficult to parse these automatically, and the number of words is small that it would be better to add them by MOD developers manually for better results.
    • Translating UIDictionary and AchievementTranslations is supported.
  • Not supported translation into Korean

    • Translation is provided by the DeepL API, so it is not possible to translate into languages that are not supported by DeepL.
  • The generated translations are “not” perfect

    • It is a machine translation though DeepL. The translations on DeepL are known to be too casual or to abbreviate some sentences.
    • It will need to be manually corrected to make it a good translation. However, this tool allows you to prototype and is more efficient than starting from scratch. Also, the CDATA tag has been removed from the translated text and must be added manually.
  • Parsing errors may occur when trying to translate manually created JSON files

    • In many cases, this is due to a specific comment in the JSON. Please remove the comments and try again.
    • Most comments are processed normally, but errors may occur if the comment contains special symbols or if the comment is located at the end of a JSON object.
