How to play Drakengard on Mac

Drakengard follows the story of a kingdomless prince named Caim who fights for the Union against the Empire. Under the Union's protection are the Hierarchs and the Goddess, currently Caim's sister Furiae, who is a human manifestation of one of the four seals that protect the world from being broken.
