Kalypso Media announces The First Templar, a cooperative action/adventure game being developed by Haemimont Games for release in Q1 2011 on PC and Xbox 360. The first The First Templar screenshots accompany the announcement, and here's a bit on the game:

The game portrays a dark and gritty view of the late 13th century where old friends become enemies, corruption spreads throughout the Church and fallen knights oppress the weak and renounce their oaths.

The First Templar follows the story of two main 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 heroes face powerful opponents at every turn, in the face of the Saracen, King Philip IV of France and the Inquisition.

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.
