Shadows over Camelot is a semi-cooperative game about the legend of King Arthur, in which players, as Knights of the Round Table, undertake various quests to defend Camelot against the forces of evil. Players move to different quests, play cards to complete them, fight siege engines, and sometimes accuse other knights of being a traitor. The Loyal Knights win if they have more White Swords than Black Swords on the Round Table when 12 swords are placed, or if all forces of Evil's win conditions are prevented.
