Loosely based on Greek mythology, the game is set in ancient Greece with vengeance as its central motif. The player controls the protagonist and former God of War, Kratos, after his betrayal at the hands of his father Zeus, King of the Olympian Gods. Reigniting the Great War, Kratos ascends Mount Olympus until he is abandoned by the Titan Gaia. Guided by the spirit of Athena, Kratos battles monsters, gods, and Titans in a search for Pandora, without whom he cannot open Pandora's Box, defeat Zeus, and end the reign of the Olympian Gods.
