Square Enix announced today that they will be relaunching their mobile RPG Kingdom Hearts Unchained χ as Kingdom Hearts Union χ.

Fans will be able to learn more about the Kingdom Hearts history with this upcoming relaunch. The relaunch will come as a free update next month and will include a new “Union Cross” multiplayer mode and more ways to customize the player’s avatar.

Square Enix had this to say about the upcoming relaunch of the mobile title:

With Kingdom Hearts Union χ[Cross], players can create teams of six from their party members or through a matchmaking feature to fight hordes of Heartless enemies and powerful bosses. Players can also take on quests of increasing difficulty as well as unique new missions. To help these teams of friends communicate with each other, the game will now include emotes and text bubbles. Players will encounter both familiar and new faces as the story of the Unions continues to unfold, and the new “Theater Mode” will allow players to relive the drama and rewatch cutscenes.

Fans who pre-register for the update on the official website will obtain exclusive smartphone wallpapers and in-game rewards.

In addition, Square Enix will be commemorating the relaunch and the one-year anniversary of the original app release by awarding players with in-game presents just for logging in after the update.

Kingdom Hearts Unchained χ is currently available as a free download for iOS and Android mobile devices.
