Jade Empire Special Edition is now available for free on Origin Games as the newest entry in their "on the house" program (thanks GameInformer). Here's word on the martial arts action/adventure, which was first released in 2005:

When danger threatens, you travel across the world, from the harsh mountains of the Land of Howling Spirits to the lush gardens of the Imperial City.

In your adventures you face powerful human and supernatural foes, learn exotic and magical martial arts, and discover the darkest secrets of the world.

Only by mastering the greatest fighting styles and defeating the most powerful enemies will you earn your place as a master of martial arts in the world of Jade Empire.
