Even though Arcanum was originally available in both French and German as well as in English, modern digital versions of Arcanum sold on Steam and GOG are English language only, thus making the localized versions quite elusive. For this reason I decided to take it upon myself to make some simple yet effective diff patches.
The below patches will transform the English version of Arcanum into the official French or German localization. Both text and audio will be patched. These language packs will work with all known English releases of Arcanum including Steam, GOG as well as retail 22.214.171.124 version.
(Unfortunately, the Unofficial Patch is not compatible with non-English versions of the game due to the amount of dialogs and scripts it modifies, however the other mods and patches are generally language independent.)
