Defender of the Crown puts the player in the role of one of four Saxon knights in medieval England, in a time where the land is in turmoil as the King is dead and his crown was stolen. The Saxons and the Normans blame each other and fight for control of England.
The gameplay revolves around building your army, taking control of additional territories and fighting against the three Norman lords. You'll also encounter some of your own Saxon friends, who may become allies or enemies.
Throughout the game, you can engage in various events and options to fine-tune your play style. This includes jousting contests, castle raids for loot or a princess's hand, and joining houses and territories to gain fame or land.
