"Suffering for years, Kratos, the once great general, now known as the Ghost of Sparta, had pledged himself as a champion to the gods of Olympus. In return, he hoped only to rid himself of the nightmares that haunted him for far too long. But for now, his only respite, his only relief from the sins of his past, was found in the heat of battle. And on this day, Kratos had been called upon by the gods to confront an unthinkable evil, unleashed on the city of Attica by the invading Persian army."
