Leaked from an upcoming issue of Famitsu is the Kingdom Hearts series' first journey onto smartphones, Kingdom Hearts Unchained Key, a port of the previously browser-exclusive Kingdom Hearts X[chi]. This announcement arrives amidst hints from Tetsuya Nomura that a smartphone title was in the works.
Kingdom Hearts Unchained Key is slated for a 2015 release in Japan, and will be free-to-play with micro-transactions and an updated gameplay system to suit the mobile way of gaming. It will also feature new plot elements for the iOS and Android versions.
The following was translated by Goldpanner following a tweet on the confirmed product.
We'll no doubt have more information when the full Famitsu article is released and translated, and when Square-Enix properly reveals the title. The game may only be confirmed for Japan at the moment, but given the teaser from Square-Enix Germany's Facebook page and Kingdom Hearts X[chi]'s relevance to the upcoming Kingdom Hearts 3, Unchained Keys will likely make its way to the palms of worldwide audiences.
