Step once more into the heart of medieval Bohemia in Mysteria Ecclesiae, a gripping new chapter for Kingdom Come: Deliverance II. When a mysterious illness strikes the secluded Sedletz Monastery, Henry is sent to uncover its source, but what begins as a mission of mercy soon spirals into a web of deceit, faith, and forbidden knowledge. Within the monastery's sacred walls, secrets fester, loyalties waver, and even salvation has a price.

Set in a stunningly realized historical environment, Kingdom Come: Deliverance II Mysteria Ecclesiae invites players to explore the Sedletz Monastery in greater depth than ever before. Once a place of worship and quiet study, it has now become a labyrinth of fear and suspicion. Every corridor, cell, and cloister hides a clue or a lie. As Henry investigates the growing crisis, he must navigate between rival factions, uncover the truth behind the epidemic, and determine who can be trusted in a time when faith itself is faltering.

This expansion enriches the core experience with new gameplay systems, quests, and items. Players can master the art of alchemy to create rare potions, don a specialized outfit suited for plague work, and wield a new weapon forged for close encounters in tight, shadowed halls. Each decision has lasting consequences that shape the story’s outcome and Henry's place in it.

Kingdom Come: Deliverance II Mysteria Ecclesiae stands as both a mystery and a moral test, weaving together the series’ hallmark realism with an atmosphere of creeping dread. The expansion delves deeply into questions of belief, corruption, and redemption, all set against the turmoil of a land on the edge of ruin.
