Set in richly detailed 3D environments, each with its own distinct styles and themes, Rau, a fierce warrior, must battle the denizens of the dark world to prevent the invoking of an ancient spell that holds the power to unleash great evil throughout the land. Along with his loyal and trusted spirit guide, Kuzo, a large black bird, Rau embarks on an exhilarating journey that requires a combination of stealth, aggressive-action moves and calculated planning. Kuzo plays a strategic role in the quest with the ability to scout ahead to perches for a better view of looming danger, retrieve items and distract opponents.
