Avatars of War now has their Warthrone 1st Edition book, in Spanish, available to download over on their website.
From the announcement:
The final Warthrone rulebook (Spanish) is available for download!
Since we published the Alpha rulebook over a year ago, hundreds of games have been played all over Spain and many players have sent their ideas, suggestions and improvements which have been applied to the rules system, to obtain the final rulebook for the 1st edition of Warthrone.
A big thank you from Avatars of War to all those who have playtested Warthrone!
