God of War: Ghost of Sparta , the second PSP title in the series, follows Kratos as he delves into his past to uncover the truth about his mother's fate and rescue his brother Deimos from the god of death Thanatos. His nightmarish visions continue to haunt him, drawing him on a perilous journey.
The gameplay is largely similar to its predecessor, with a few new mechanics added to the mix. Kratos wields his Blades of Athena once again, which can now be empowered with the magic of Thera's Bane, resulting in stronger attacks. Other new magic items and a secondary weapon are also introduced. The game features a story mode, as well as a "Temple of Zeus" location where players can spend orbs collected in the Battle Arena to purchase art and bonuses.
