Final Mix in a set, Kingdom Hearts II Final Mix+. A manga series ran in Monthly Shōnen Gangan in Japan, and was later released in the United States. It is accompanied by three novels—two set during Sora's storyline and the third during Reverse/Rebirth, Riku's story. Like with the Final Fantasy games and the first Kingdom Hearts game, Square released an Ultimania book on Kingdom Hearts: Chain of Memories following the release of the game. In North America, BradyGames released a strategy guide with a comprehensive walkthrough. Re:Chain of Memories Kingdom Hearts: Chain of Memories was remade for the PlayStation 2, titled Kingdom Hearts Re:Chain of Memories. It was developed by Square Enix's fifth Product Development Division, based in Osaka, and released as the second disc of Kingdom Hearts II Final Mix+ in Japan on March 29, 2007 and as a standalone title in North America on December 2, 2008. It has not been released in Europe or Australia for the PlayStation 2, but has seen a worldwide release as part of Kingdom Hearts HD 1.5 Remix. The remake includes polygonal 3D battles and worlds using the same graphics as Kingdom Hearts, as well as voice acting and an improved soundtrack. While the card-based battle system and room synthesis aspects of the gameplay stayed mostly the same, there were additions, such as the "Reaction Command" function from Kingdom Hearts II. Voice-acted scenes occur only in Castle Oblivion, as well as in the Destiny Islands and Twilight Town simulations. The remake also includes new cutscenes and battles that were not in the original game. IGN ranked it as the 92nd best PlayStation2 game. The staff felt that it stood out among other card-based RPGs. Manga Like the first Kingdom Hearts, Chain of Memories was adapted into a manga by Shiro Amano, following the same plot as the video game. It was serialized in Square's Monthly Shōnen Gangan in Japan, then released in two volumes in Japan and later in the United States by TOKYOPOP. The first volume was released in Japan on October 22, 2005. A year later, it was released in English on October 10, 2006, followed by the second volume on February 6, 2007. The manga series has had moderate success. The first volume was ranked 112th on USA Today's "Top 150 best sellers" during the week of its release. IGN praised Amano's renditions of the characters and the humor
