I tried the link to that French naval mod however it doesn't seem to work. Does anyone else have this problem?
Harpoon 3 Advanced Naval Warfare is in the final stages of beta testing so it should be released fairly soon. This version is multi-player capable! Yay!!
is a forum where you can discuss the game and whatnot, mainly H3 players (and the actual designers, and scen makers etc etc). Small but "effective" group.
