It's really funny to hear the Commandos speaking in another language.
Still looking for other languages of this game...

Thanks. Up until now I had separate installs for each language. I've never found the French version. CBTCOD is called 'le sens du devoir' I think.

Update: Italian and French language files are now available.

Great! I've been trying to torrent these, but I'm only halfway the Italian one. Thanks.

You think these are all languages? Or maybe try to find Korean :-)
