"Marking Kratos' second foray into portable gaming, God of War: Ghost of Sparta stands as a spin-off nestled between the events of God of War and God of War II. Despite ascending to the title of the god of war, Kratos remains haunted by nightmarish visions. One such vision compels him to embark on a new journey when he witnesses his mother, Callisto, imprisoned in Atlantis under the dominion of the sea god Poseidon. Against Athena's counsel to ignore the vision, Kratos sets forth to unravel his past and, in the process, rescue his long-lost brother, Deimos, from the clutches of the god of death, Thanatos.
