As in the previous games, the player can also find Gorgon Eyes and Phoenix Feathers in large chests, as well as Minotaur Horns, a new item for the game. The player also collects red orbs by killing foes and destroying certain inanimate objects. Green orbs replenish the player's health, blue orbs replenish magic allowing further usage, red orbs provide experience for upgrading weapons-which subsequently upgrades magic and makes new, more-powerful attacks available-and white orbs (replacing the gold orbs in God of War II) replenish the Rage meter for the Rage of Sparta, allowing further usage of the ability. The player finds chests colored green, blue, red, or white, and each chest contains orbs or the corresponding color. The Blade of Olympus is retained, however, it is no longer a primary weapon it is now used in conjunction with the special ability, the Rage of Sparta (equivalent to the Rage of the Gods in God of War and Rage of the Titans in God of War II), and provides temporary invulnerability and increased attack damage. Kratos acquires a new relic (similar to Poseidon's Trident) called Hades' Soul, which allows him to swim in the River Styx without being attacked by lost souls. The relics, Poseidon's Trident, Golden Fleece, and Icarus' Wings, acquired in previous games are automatically retained. the Head of Helios acts as a lantern in dark areas and can reveal hidden doorways). All three are required to advance in certain stages of the game (e.g. These include the Bow of Apollo, the Head of Helios, and the Boots of Hermes. Kratos also acquires three secondary weapons, known as "Items", which have limited use before requiring recharging (which occurs automatically). the Army of Sparta summons a flank of Spartans that cover Kratos in shields while arrows fall from the sky). The use of magic offers Kratos a variety of ways to attack and kill enemies (e.g. Unlike previous games in the series, magical abilities are learned with the acquisition of a new weapon, with each weapon having its own magic: the Army of Sparta can only be used when the Blades of Exile is equipped, just the same, the Nemean Roar can only be used when the Nemean Cestus is equipped. Although Kratos begins the game with the Blades of Athena and the Blade of Olympus at maximum power, he loses these after an encounter with Zeus (the Blades of Athena are replaced with the Blades of Exile and the Blade of Olympus is recovered). For example, the Nemean Cestus are required to break through things made of onyx. The Nemean Cestus (a pair of fist gauntlets) and the Nemesis Whip (similar to the blades) are required to advance in certain stages of the game. As the game progresses, Kratos acquires new weapons-the Claws of Hades, the Nemean Cestus, and the Nemesis Whip-offering alternative combat options. The blades can be swung around to attack enemies. Kratos' main weapon is the Blades of Exile (initially the Blades of Athena): a pair of blades attached to chains that are wrapped around Kratos' wrists. Some puzzles are simple, such as moving a box so that the player can use it as a jumping-off point to access a pathway unreachable with normal jumping, but others are more complex, such as finding several items across different areas of the game to unlock one door. Platforming elements require the player to climb walls, jump across chasms, and swinging on ropes to proceed through sections of the game. Some enemies were created specifically for the game, such as Olympian legionnaires (soldiers). Kratos is guided through various environments while fighting enemies, who come mostly from Greek mythology, such as Gorgons. The player controls the character Kratos in combo-based combat, platforming, and puzzle game elements. The game also features a first-person camera view during two boss battles (a first for the series). It is a third-person single player video game viewed from a fixed camera perspective. The gameplay of God of War III is similar to that of its predecessors.
