As punishment for breaking this oath, Kratos is sentenced to an eternity chained within a prison for the living damned while enduring endless torture by the Furies who want to break his mind. Kratos will have to battle his way through the prison as he seeks his freedom, redemption, and the clarity to avenge his family.
In December 2008, Sony reported that God of War III would be the last game in the series. However, in January 2010 John Hight told Joystiq: "While God of War III will conclude the trilogy, it won't spell the end of the franchise ... We're going to be really careful about what we do next". Asmussen mentioned the possibility of downloadable content; the game would be shipped with the regular challenge mode, and new challenge modes might be released as downloadable content to maintain the series. In March 2009, it was reported that Sony was seeking opinions about a collector's edition from PlayStation 3 owners. In October, an Ultimate Edition was unveiled for North America, and an Ultimate Trilogy Edition was announced soon afterwards for a limited European, Australian, and New Zealand release. A Trilogy Edition was announced for Japan, where the Computer Entertainment Rating Organization (CERO) gave the game an adults-only Z rating after the previous two versions were considered suitable for players 17 and older.
The engine for God of War III was from the first two installments. Santa Monica senior producer Steve Caterson said that the development team ported God of War II's engine to the PlayStation 3 and were able to quickly play the game. Everything that Kratos could do in previous games, he could do on the PlayStation 3, which allowed the developers to immediately begin designing new content. As the game was being developed, the code department would swap out PlayStation 2 components with PlayStation 3 components. They replaced the renderer, the particle system, and the collision system. Feldman said that although they were re-using the engine from God of War II, the core engine for God of War III was brand new. Between the 2009 Electronic Entertainment Expo (E3) and the time the game shipped, morphological anti-aliasing (MLAA) was added, which graphics engineer Ben Diamand said "improved edges dramatically and saved substantial amounts of frame-rate." MLAA is "now a popular edge-detection process that can cost-effectively remove jagged edges from each frame", which helped Santa Monica free up the processing cycle and "allowed them to add to the spectacle in other ways." Diamand also said that "depth-of-field, motion blur, crepuscular 'god' rays and refraction were either added or improved in quality and speed" during that same time period.
At E3 2009, the God of War III demo was unveiled, with Kratos on the cliffs of Mount Olympus battling Olympian legionnaires, a centaur, a chimera, and a cyclops. He decapitates Helios, encounters Perses, rides harpies, and uses the Blades of Athena and new weapons (the Nemean Cestus and Bow of Apollo). On October 28, 2009, SCE Europe sent emails to PlayStation Network members with an activation code for the demo. On October 30, GameStop began providing voucher codes for customers who pre-ordered the game, and early copies of God of War Collection had a voucher code to download the demo. The Blu-ray version of District 9 included the God of War III demo and a "making of" featurette, and the demo was released to Qore subscribers on February 4, 2010. On February 25, Sony Computer Entertainment released the demo for download on the PlayStation Store in Europe and North America. Just before the game's release, Eurogamer published an article comparing the graphics in the God of War III demo to those in the final game, reporting improved lighting and realistic motion blur in the final release.
In October 2009, Santa Monica Studio announced the God of War III Ultimate Edition, available by pre-order in North America. The package included a replica Pandora's Box, a limited-edition The Art of God of War III book, and downloadable content (DLC) from the PlayStation Network, which included the "Challenge of Exile" mode, Kratos' "Dominus" costume, the God of War: Unearthing the Legend documentary, the God of War Trilogy Soundtrack, and the God of War: Blood & Metal EP. A limited Ultimate Trilogy Edition was released in Europe, Australia, and New Zealand and included the contents of the Ultimate Edition, as well as God of War Collection, four Kratos costumes, and God of War postcards. A God of War III PS3 bundle, with a 250GB PS3 and a copy of God of War III, was also available in Europe. A God of War III media kit with special packaging and content was distributed to journalists in the PAL regions, and several were given as prizes on PlayStation Europe's website during the week of March 22, 2010. In Japan, God of War III was released in two packages: a standalone version and a God of War Trilogy Edition. The latter included God of War III, God of War Collection, an art book, and a Kratos skin.
For pre-orders, some retailers included a premium costume for Kratos: the Apollo, Forgotten Warrior, and Phantom of Chaos skins from Amazon.com, Game Crazy and Play.com, and GameStop, respectively. GameStop pre-orders also included a 17-by-24-inch (43 cm × 61 cm) poster signed by God of War III concept artist Andy Park and an entry in its "Be the Envy of the Gods" sweepstakes. 7-Eleven issued a God of War III poster for pre-orders and sold a Kratos' Fury Slurpee in God of War III cups. The cups and their specially marked Mountain Dew bottles had codes usable on the Slurpee website for God of War III downloadable content, including a behind-the-scenes video, wallpapers, PlayStation Home content, and an in-game Kratos skin, the Morpheus Armor.
The game has 36 trophies, awarded for player achievements (for example, "Releasing the Floodgates" for killing Poseidon). When players received the platinum trophy, they were linked to the website spartansstandtall.com. On May 4, 2010, the site became the official website for God of War: Ghost of Sparta, the next installment in the series and the second for the PlayStation Portable. Early copies of Ghost of Sparta (and all digital copies in Europe) included a voucher to download Kratos' brother Deimos as a costume for use in God of War III.
God of War III Remastered is a remastered port of God of War III for the PlayStation 4 console. It was first released in North America on July 14, 2015, followed by Australia and mainland Europe on July 15, and the UK on July 17. Santa Monica's Creative Director Cory Barlog announced the remastered game in celebration of the God of War franchise's tenth anniversary. Ported by Wholesale Algorithms, the remastered version has full 1080p support targeted at 60 frames per second and features a photo mode, allowing players to edit their photos and share their favorite moments. All of the DLC that was released for God of War III is included with God of War III Remastered. By the end of its first week of release, God of War III Remastered was ninth in sales at retail in the UK. For the entire month of July 2015, the downloadable version was the seventh best-selling PlayStation 4 title from the PlayStation Store.
In March and April 2010, God of War III: Original Soundtrack from the Video Game, composed by Gerard K. Marino, Ron Fish, Mike Reagan, Jeff Rona, and Cris Velasco, was included as downloadable content in the God of War III Ultimate Edition and Ultimate Trilogy Edition. Its CD was released on March 30 by SCE and Sumthing Else. The soundtrack was recorded by the Skywalker Session Orchestra and the Czech National Symphony Chorus. Each composer provided a different aesthetic to the score: for example, Marino's approach was brooding, rhythmic, and percussive, and Fish set hopeless and somber moods. In an interview with Game Music Online, Mike Reagan said that although the composers might have used each other's themes, they did not collaborate with each other. Reagan said the real collaboration came from Clint Bajakian, Senior Music Supervisor at Sony, and his team. In scoring for God of War III, Reagan said that the composers were "able to explore more melodic development than we were on the first [God of War]." The score was recorded under the new American Federation of Musicians video game agreement and because of Sony's vision and support, the composers were able to record locally with some of the best musicians in the world. In an interview with PlayStation.Blog, Clint Bajakian described the different ensembles that recorded the score: the brass section is the "lead guitar", the choir gives the game its epic feel, the strings are the body of the sound, and the percussion is the foundation.
A free-for-all sandbox campaign focused on a Daemonic invasion of Grand Cathay, where players fight for control of key settlements. Players can join in as Grand Cathay, Ogre Kingdoms or one of the four Chaos Daemon races (Kislev and the Daemon Prince do not feature).
A free download of the demo, desktop wallpaper, character profiles, and more are available on the Morning's Wrath website at Morning's Wrath is available for sale in electronic download version for $19.95 and $29.95 in CD format.
