Paradox Interactive has officially announced All Under Heaven, the largest expansion yet for Crusader Kings III. The update takes players beyond the familiar borders of medieval Europe and into the vast, intricate realms of East Asia.

Paradox Interactive has revealed All Under Heaven, a major expansion for Crusader Kings III set to launch on October 28, 2025. Described as the grand strategy game’s largest and most ambitious expansion to date, it introduces entirely new regions - from the Great Wall of China to the temple cities of Southeast Asia - offering fresh opportunities for diplomacy, conquest, and intrigue.

The update extends the playable map to include China, Japan, and Southeast Asia, each with its own government systems, traditions, and power struggles. In China, rulers will navigate the Dynastic Cycle, balancing stability and chaos while vying for the Mandate of Heaven. Players can rise through the ranks of the Celestial Government, earning merit through deeds or imperial examinations to secure favour within the Emperor’s court.

In Japan, players can shape the rise of the Shogunate, guiding noble houses through court politics, alliances, and ritual battles as they pursue power as Shogun or Kampaku regent. Southeast Asia introduces the Mandala Government, allowing rulers to form vast temple-centred empires and unify tributary states under divine rule.

Alongside the massive world expansion, All Under Heaven adds Japanese language support, new Silk Road trade systems, historical bookmarks, and rich cultural details inspired by medieval Asia.

“This expansion fulfills one of our great ambitions,” said Game Director Alexander Oltner. “You can’t tell the full story of the medieval world without East Asia.”

Crusader Kings III: All Under Heaven launches October 28 for $29.99 / £24.99 / €29.99, and is included in the Chapter IV Expansion Pass.
