Crusader Kings Complete invites you to navigate the treacherous political waters of medieval Europe, where fragmented territories are rife with conflict and intrigue. As a ruler from one of the Great Christian Dynasties, you will strive to unite vassals and build a powerful nation. The call of the Pope rings out, urging the faithful to free the Holy Land, promising absolution for those who join the crusade. Can you seize this opportunity to elevate your name and legacy?

With historical multiple-choice events unfolding based on your actions, each decision can impact your realm over 400 years of gameplay. Engage in epic campaigns during pivotal conflicts like the Hundred Years War, the Crusades, and the Mongol Wars. Strengthen your holdings by constructing grand cathedrals and castles, while also combating internal threats like highway bandits and rebellious vassals.

Interact with a vast array of courtiers and nobles, introduce laws, set taxes, and build alliances. Choose to lead renowned religious orders, such as the Knight's Templars or the Teutonic Order, and participate in fierce multiplayer battles alongside up to eight players. Will you rise as a true Crusader King?
