Warhammer 40,000: Rogue Trader

The Infinite Museion launched in June 2026 as the third story expansion for Warhammer 40,000: Rogue Trader, adding new quests, narrative elements, an encounter with Trazyn the Infinite, and the Tech-Priest Manipulus companion. Its augmentation layer created a major new progression path, while Processional of the Damned was announced as the final expansion but remained unreleased after its delay.
