The final story expansion, Mysteria Ecclesiae, has been released for Kingdom Come: Deliverance 2

Warhorse Studios has released Mysteria Ecclesiae, the final storyline DLC for the action RPG Kingdom Come: Deliverance 2. In the new DLC, hero Henry travels to the monastery in Sedlec, where he must investigate an outbreak of a deadly plague and discover the source of the infection threatening the monks and surrounding villages. The add-on features a dark atmosphere, combining elements of exploration with the series' traditional medieval realism.

Mysteria Ecclesiae is the third and final major DLC for the game: the studio previously released Brushes With Death in May, in which Henry assisted a mysterious artist, and then Legacy of the Forge, in which the protagonist returned to Kutná Hora and restored his father's forge, with the option to expand it and furnish his personal quarters.

The original game launched on February 4th and is available on PC, PlayStation 5, and Xbox Series X|S; with the release of the final DLC, the developers conclude their planned post-release support cycle.
