God of War: Rakujitsu no Hisoukyoku

Kratos makes his first appearance on a portable platform in the third title in the God of War series. Chains of Olympus is a prequel set ten years before the original God of War. Gameplay is similar to the predecessors but with some minor changes. Kratos goes through levels killing enemies and bosses, solving box-based puzzles and doing quick time events. He also collects red orbs to power up his weapons and abilities, Gorgon eyeballs to increase his health and Phoenix feathers to increase his magic power.

The game's controls were adjusted to fit the PSP's reduced amount of buttons. Both the shoulder buttons and the analog stick are now required in order to dodge. The most well-known God of War weapon, the Blades of Chaos, are also present. There are several new weapons and magic spells available, including Sun Shield, Efreet spell and Light of Dawn. The game starts when the Gods send Kratos to the city of Attica to defend it from the invading Persian army. But later when Morpheus strikes, Kratos will need to use all his power to save the world once again.
