Do you know if 2.0.35 patch works with french version of the game ?
Patch works with every "version" of Original War and every distribution platform (Retail, Steam, GoG, etc).
Does the patch adds language strings ? If yes, does it include foreign language files ?
All languages subtitles are included. Dubbing (Voices) are not included in the patches but can be downloaded from Here
. Dubbing is only needed if the version you have does not include the language you want it to be in (If you have a french version you don't need to download French Dubbing).
