Players use their characters' special abilities and the cards they draw throughout the game in order to complete quests, compete in tournaments and battle Saxons and Picts. Players work together to complete the quests before accumulating enough defeats or character deaths to cause the game to end.
The game has had several expansion sets:
- Sir Bedivere. This character was released as a reward to people who pre-ordered the game.
- A Company of Knights
- Merlin's Company
