From the Great Wall to the great temple cities of Indochina, from the foothills of Mount Fuji to the river valleys of China, an infinite array of new adventures and stories awaits you in All Under Heaven, the largest expansion for Crusader Kings III to date. The newly expanded map presents a rich and colorful setting for imperial ambition, sacred duties and shadowy scheming with detailed representations of medieval China, Japan and Southeast Asia.
Coming on 28 October, All Under Heaven takes your campaigns to entirely new settings, unseen in any previous Crusader Kings game. Keep a steady hand on the regional hegemon or manage the tumult of dynastic change in China. Revere the Yamato emperor and his regent in Japan, or pursue the path of the samurai warlord. Build a monumental temple facility in the jungles of Southeast Asia and compel weaker kingdoms to pay tribute to your greatness.
All Under Heaven also introduces Japanese as a supported language for Crusader Kings III, further expanding the international audience that has grown to support this royal game.
