The First Templar follows the story of two characters -a French Templar, and his companion, a noble lady who has been proclaimed a heretic. Taking control over these two unlikely allies, the player must uncover the mysteries behind the Templar Order, play a role in a grand conspiracy, and discover the secret of the Holy Grail.
The First Templar features both single player and co-op modes. When playing solo, the player can switch between the two characters, leaving the control of the second hero to the game's AI. At any moment a second player can join in and take control of the AI controlled hero.
