God of War: Chains of Olympus is an action-adventure game developed by Ready at Dawn for the PlayStation Portable and prequel to God of War. Loosely based on Greek mythology and focused on protagonist Kratos, the game forms part of a saga - the God of War series - with revenge as a central theme. In this chapter, Kratos opposes the goddess Persephone (who allies the god Morpheus and Titan Atlas) in her attempt to destroy the world and Mount Olympus. The game is similar to other installments in the series, and is a third-person action adventure game containing quick time events, box-based puzzles and boss fights. Kratos' weapons includes the trademark "Blades of Chaos" and new weapons the Sun Shield and Gauntlet of Zeus. New magical abilities include the use of an Efreet; the "Light of Dawn" and "Charon's Wrath". Health and Magic upgrades - Gorgon Eyes and Phoenix Feathers respectively - reappear in addition to normal Health and magic-giving chests. In addition to an array of normal opponents (such as soldiers; harpies; gorgons and the cyclops), major foes include a Persian King, a giant basilisk, the ferryman of the dead Charon and the goddess Persephone.
