ChristianStrahl: There is a inofficial Italian translation for practically all the Text.
There might is the same thing in French.
How ever as Plokite_Wolf pointed out there is not a offical French version, so there are no professional French voice overs for this game.
-- If you should feel the urge to create a translation read on --
There is a Mod that contains the files that you would need to look at if you would ever decide to make your own French Translation:
https://www.moddb.com/mods/colony7-for-ef2/downloads/german-english-dual-compatibility-languagepack PK3-Files can be opened with a Archiver like 7-Zip or any other Program that can open ZIP files, as they are basically renamed ZIP-Archives.
The relevant files that would need to be modified have the extension .loc, but are basically just renamed text files and can be opened with Notepad.
This is where the loc-files would be located in that Mod:
ef2_sprachpacket_languagepack_de_en_v2.zip\english\zlocpak3_text-en.pk3\loc\Eng\stringresource\
You can extract the loc-files to your game folder and edit them from there start the game and see the changes.
If you don't have these folders in your game install folder, create them, except for the /base/ folder as it should already exist.
/base/loc/Eng/stringresource/
Thank you very much for this informations, the German mod that allows to edit the texts seems promising. I will look at what I can do with it.
