God of War: Chains of Olympus

God of War: Chains of Olympus is an action-adventure game developed by Ready at Dawn and released by Sony Computer Entertainment for the PlayStation Portable (as the fourth God of War game and the first for the PSP) in March 2008.

Gameplay
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.

A Challenge mode (the “Challenge of Hades”) is also included in the bonus features, which unlocks a secret costume and a behind-the-scenes video.
