If your version lacks French or you need to fix broken localization files, community members often host patches on dedicated translation sites:

Il n’y a pas de doublage vocal français . Le patch ne remplace que les textes. Les personnages parlent toujours en anglais – c’est normal.

: The safest place to find direct, curated links to language switchers and widescreen fixes is the Steam Guide section for I Am Alive . Search the guides using the keyword "French" or "FR".
