Which studio developed God of War: Ghost of Sparta for PlayStation Portable?

Ready at Dawn developed God of War: Ghost of Sparta for PlayStation Portable. The studio created the handheld title in collaboration with Santa Monica Studio, which supervised the broader God of War franchise.

Ghost of Sparta was released in 2010 and follows Kratos during the Greek mythology era of the series. Its story explores his search for his brother Deimos and adds background to Kratos's family history and his relationship with his mother, Callisto.

The developer is often confused with Santa Monica Studio because Santa Monica created the main console entries and is prominently associated with the franchise. Ready at Dawn also developed God of War: Chains of Olympus, another PSP prequel. Ghost of Sparta was designed to bring the series' combat, cinematic presentation, and mythology to Sony's portable system.
