Assuming you have obtained your english.txt file, here is how to use it to fix common game errors:
Error: "Corrupt Localization Data"
Error: Text shows as "KEY_NOT_FOUND"
You generally do not need to download this file if you bought the game directly from Steam in the US, UK, Canada, or Australia. However, common scenarios include:
First, understand what you are dealing with. The localization.txt file in Call of Duty: Black Ops 3 is not a massive texture pack or a gameplay patch. It is a plain-text configuration file that tells the game engine which language database to load for UI elements, subtitles, mission briefings, and weapon descriptions.
When the game launches, it reads:
If this file is corrupted, missing, or incorrectly configured for your region (e.g., a Russian key trying to force Cyrillic), the game defaults to placeholders or error messages.
If you downloaded the English localization TXT but still see errors:
Inside the main game folder, look for a file named localization.txt. If it exists, right-click it and select Copy, then paste it to your desktop as localization_backup.txt. This ensures you can revert if something goes wrong.
