text: Combat Kratos' main weapon is the Blades of Chaos: a pair of blades attached to chains that are wrapped around the character's wrists and forearms. In gameplay, the blades can be swung offensively in various maneuvers. As the game progresses, Kratos acquires new weapons—the Sun Shield and Gauntlet of Zeus—offering alternative combat options. Kratos only learns three magical abilities, as opposed to four in previous installments, including the Efreet, the Light of Dawn, and Charon's Wrath, giving him a variety of ways to attack and kill enemies. He acquires the relic Triton's Lance—similar to Poseidon's Trident in God of War— which allows him to breathe underwater; a necessary ability as parts of the game require long periods of time there.
  The challenge mode in this game is called the Challenge of Hades (five trials), and requires players to complete a series of specific tasks (e.g., Burn 50 soldiers with the Efreet). It is unlocked by completing the game. The player may unlock bonus costumes for Kratos, behind-the-scenes videos, and concept art of the characters and environments, as rewards. Completion of each of the game's difficulty levels unlocks additional rewards.
  Synopsis
  Setting
  As with the previous games in the God of War franchise, God of War: Chains of Olympus is set in an alternate version of ancient Greece, populated by the Olympian gods, Titans, and other beings of Greek mythology. With the exception of flashbacks, the events are set between those of the games Ascension (2013) and God of War (2005). Several locations are explored, including the real-world locations of the ancient cities of Attica and Marathon, the latter including fictional settings of the Temple of Helios and the Caves of Olympus, and several other fictional locations, including the Underworld, which features scenes at the River Styx, Tartarus, the Fields of Elysium, and the Temple of Persephone.
