God of War: Chains of Olympus is an action-adventure game where the player controls Kratos, a Spartan warrior who serves the Olympian Gods. This game is the fourth in the God of War series, as well as a prequel to the first God of War. It is largely based on Greek mythology and is set in ancient Greece, with the major theme of retribution.
The goddess Athena directs Kratos to seek out the Sun God Helios, as the Dream God Morpheus has put many of the gods to sleep due to Helios’ absence. Morpheus and Persephone, Queen of the Underworld, plan to demolish the Pillar of the World, and therefore Olympus, using the Sun’s strength and the Titan Atlas’ help.
