Nali Weapons 3 is a new weapon pack for Unreal Tournament, containing over 15 new weapons, including nuclear weapons, drones, freezing and flaming guns, and the list goes on... It's also the sequel to the old Nali Weapons II X.
Localization files meant to be translated into other languages, in order to translate captions, labels, messages and other text for Nali Weapons 3 mod itself.
All the *.int files present here are localization files, and are meant to be translated into other languages, in order to translate captions, labels, messages and other text to the Nali Weapons 3 mod itself.
These files are only meant for the latest and final version of the mod, therefore if a previous version is still used, it must be updated to the final version first, in order for these to work.
In order to translate the text from these files, the text must be modified directly.
Optionally, in the end you may change the extension of the files from *.int to the extension belonging to the language the text is being translated into, as recognized by the game:
However, in order for any of these extensions to work, the Language entry in the UnrealTournament.ini file, under the Engine.Engine section, but be changed from Language=int to the corresponding language, such as Language=est for Spanish, for example.
Given the age of the game and the limited localization support concerning the languages supported through these extensions, it's preferable however to leave them as is, with the *.int extension, in order to work with most, if not all, game installations.
