Hello, I'm not a member of the team but a player. The forum is quite messy and I spent last night hours to find the right links and latest version of the mod. So here are the links, for players who want to play them. A guy named King_Z, who seems to be a member of the team, uploaded the mod at ModDB last year but used the wrong RS2 Environments addon. His one is not working and the climate of Britannia is Mediterranean-type. I finally managed to find Granto's RS 2 Environments addon and I uploaded it myself.
So here are the links, download and install them in that order :
Download links:
Just download, extract the content into your "Rome Total War" or "Rome Total War Gold" folder and play using "Arthurian Total War" executable which is in the game directory when the installation is finished.
Remember that in order to play the mod campaign, you will have to click on "Provincial Campaign" and not "Main Campaign" when the game is launched.
