The original expansion campaign translated from Italian.
To install, just unzip the .wcm file in the "Campaign" folder.
This is a fan made translation of the original "Tzar: Excalibur e il Re Artù" campaign from the Italian version of the game.
Special thanks to darthdoull for helping me with the dialogue and proofread the translation.
Trivia: this campaign is one of the four expansions released in Spain, while in Italy the game was published by FX Interactive as "Tzar: Excalibur e il Re Artù". So this is the main campaign for Italian players, along with "L'impero di Gensis Khan" (one of the Spanish expansions) as a secondary campaign. There is no official Italian version of "The Burden of the Crown".
