Crusader Kings III: All Under Heaven was revealed on October 8, 2025, with Paradox Interactive announcing a release later that month. It launched on October 28, 2025, so “later this month” in the original headline refers to October 2025—not an upcoming release. The expansion brings China, Japan, and Southeast Asia into the game with distinct political systems and regional mechanics.
What All Under Heaven adds to Crusader Kings III
Paradox described All Under Heaven as the fourth major expansion for Crusader Kings III. Its October 2025 launch announcement says it adds “thousands of new provinces and characters”; that is the publisher’s description, and it does not give a more exact total. The reveal called it the game’s “largest expansion” to date, also a publisher characterization rather than an independently measured comparison. Paradox’s reveal and release announcement frame the addition as a way to extend the game’s medieval world into East and Southeast Asia.
The expansion is not just a larger map. Its announced features give China, Japan, and Southeast Asia different routes to power, political structures, and regional activities. Paradox also highlighted the Silk Road, new starting bookmarks, events, traditions, and throne rooms.
How the three regions differ
China: imperial authority and the Dynastic Cycle
China’s systems center on the Hegemony title and Celestial government. Rulers can earn Merit through deeds or Imperial Examinations, while the Dynastic Cycle gives imperial rule a distinct political framework. The Imperial Treasury can be used for Great Projects, disaster response, and statecraft.

Why Paradox says the expansion reaches East Asia
“We’ve always seen Crusader Kings as the story of the entire medieval world, and you can’t fully tell that story without East Asia,” said game director Alexander Oltner in the October 8, 2025 reveal. That framing helps explain the expansion’s scope: it pairs a wider playable world with regional political systems rather than treating East Asia as a uniform map extension.
