Kingdom Hearts χ


stylized as Kingdom Hearts χ, is a Japanese role-playing browser game developed by Square Enix, BitGroove and Success, and published by Square Enix for web browsers as the eighth installment in the Kingdom Hearts series. Gameplay involves players navigating a customized avatar through Disney-inspired worlds fighting enemies, along with taking down bosses in multiplayer matches in competition with other teams. A version of the game for mobile devices called Kingdom Hearts Unchained χ, was released as the ninth installment of the series in Japan in September 2015, and worldwide in 2016. In April 2017, Unchained χ was rebranded as Kingdom Hearts Union χ. It was rebranded once again in June 2020 to Kingdom Hearts Union χ Dark Road with the release of the stand alone game Kingdom Hearts Dark Road, the thirteenth installment in the series. Dark Road is accessed within Union χ.
Kingdom Hearts χ is a prequel to the Kingdom Hearts series as a whole, taking place centuries prior. It takes place before the Keyblade War, which established the organization of the Kingdom Hearts universe as of the original game. The player assumes the role of a Keyblade wielder who joins one of five factions led by Keyblade Masters fighting for control of the limited light existing in the world. Unchained χ/Union χ acts as a sequel, retelling part of the story of Kingdom Hearts χ before diverging and telling a new story set after its events. The game's plot is connected to Kingdom Hearts III. The title refers to the χ-blade, a weapon central to the series' story arc. Kingdom Hearts Dark Road explores the origins of series antagonist Xehanort and his eventual turn to darkness.
The game was designed as a playing experience that newcomers to the series could come to. Its presentation was compared to that of a fairy tale, as depicting the usual style of the series would have been difficult on the platform. Both Tetsuya Nomura and Yoko Shimomura, veterans from the main series, returned as director and composer respectively. The game received favorable reception from critics. A companion film, Kingdom Hearts χ Back Cover, was released as part of Kingdom Hearts HD 2.8 Final Chapter Prologue in January 2017.

Gameplay

Kingdom Hearts χ is a role-playing video game set in the universe of Kingdom Hearts which includes original characters and locations as well as ones from Disney and Final Fantasy media properties. Before beginning, players create their own character. Players can customize the gender, hair, and clothing, and choose accessories themed after both Square Enix and Disney universes present in the Kingdom Hearts series. Story missions are unlocked by the player. After a certain amount of the available content has been completed, new story missions become available. Players navigate their surroundings by dragging their cursor across the screen. Players navigate different worlds, defeating monsters known as the Heartless. The base game is free to play, with optional microtransactions. Actions use up AP, which can be replenished by either waiting or by using potions, which can be earned or bought. Rare items such as special cards can also be purchased. Alongside the single-player mode, there is a multiplayer mode where teams of players take on Raid Bosses, gigantic Heartless with high HP.
Enemies appear on-screen, and can be engaged by clicking on them. During the player's turn, three cards are randomly drawn from a deck of nine, each resulting in an attack. If the cards' combined strength and attached skills are insufficient to exhaust the enemy's HP, the heartless will counterattack. If the player survives this attack, or continues by spending additional AP, a new turn begins. Upon defeating an enemy, the player earns Lux, experience points, and Munny. The player also earns Fragments, cards based on the characters original to the Kingdom Hearts series and those from Disney and Final Fantasy franchises: the fragments are imbued with different properties depending on the character, such as physical or elemental strikes. Players can level up their cards to improve their attack and defense. Players can strengthen their Keyblade using materials found in each world, and new Keyblades are acquired as the story progresses. Each strengthens different types of cards; for example, Starlight is an all-around Keyblade offering boosts for Power-, Speed- and Magic-type cards, while the Snow White-inspired Treasure Trove is Power-type focused.
The mobile version of the game, entitled Kingdom Hearts Unchained χ, shares multiple gameplay features with its browser counterpart: the main exception is that this version is tailored for a touch screen. The ability to travel freely between different Disney worlds is also replaced with a stage system. These stages, called quests, are confined to specific areas of specific worlds. Instead of spending AP on individual actions, AP is paid to start a quest, and the player can attack as many enemies, collect as many materials, and open as many chests as he or she can find before defeating a target Heartless. If the player's HP is fully depleted, a choice is offered between forfeiting all progress in the quest or continuing to fight by spending Jewels, a new general-purpose in-game currency. Lux is considered another name for character-leveling experience points. Clothing, hair, and accessories are obtained through Avatar Boards, which each contain an array of nodes on branching pathways. These nodes are unlocked, in set sequences, with Avatar Coins, and may also yield such benefits as increased limits for AP and HP. Cards from the browser version are here replaced by Medals, which are no longer drawn randomly in battle. Instead, each equipped Medal is presented one at a time, and the player is given the choice of attacking one enemy, attacking all enemies, or using the special attack granted by the Medal. Medals can be combined with matching Medals to improve their special attacks.

Synopsis

Setting

Kingdom Hearts χ is set in a world called Daybreak Town in the distant past, prior to the other games in the series. The game begins before the legendary Keyblade War, a conflict sparked due to disputes between Keyblade wielders over the light that created the world, triggering a calamity that reshaped the world into that seen in the rest of the Kingdom Hearts series. Prior to the war, a precognizant Keyblade Master known only as the Master of Masters bestows a Book of Prophecies to five of his six apprentices, the Foretellers, before disappearing. The book has the ability to manifest objects and people from the future, and contains an account of future events, from which the five Foretellers learn of a prophecy foretelling the world's destruction. To prevent this, the Foretellers use their books to manifest future worlds and defeat the Heartless infesting them to gather pieces of light, called Lux. Each Foreteller creates and leads their own "Union" themed around their individual animal icon: Unicornis, governed by Ira; Anguis, governed by Invi; Leopardus, governed by Gula; Vulpes, governed by Ava; and Ursus, governed by Aced. The player character, a newly awakened Keyblade wielder, chooses to support one of the Unions and works to ensure the chosen faction's supremacy.
Kingdom Hearts Unchained χ takes place after the events of Kingdom Hearts χ in an alternate data worldline, with the player reliving the past to forget the events of the Keyblade War. Due to the Book of Prophecies' loss of power without the Master or Foretellers present, the Keyblade wielders instead visit simulated datascapes based on the various Disney worlds. Unchained χ initially repeats the story of the original, but diverges partway through the narrative. New stories feature the player forming a new team with four other Keyblade wielders, who become friends. Other major story events that do not involve the player are delivered via game updates, serving to expand on the story of Kingdom Hearts χ and continue the narrative after the events of the Keyblade War.
Kingdom Hearts Dark Road is set many years after the Keyblade War, between the events of Unchained χ and Kingdom Hearts Birth By Sleep. The story explores the origins of series antagonist Xehanort and his eventual turn to darkness.

''Kingdom Hearts χ'' story

The player character awakens as a Keyblade wielder and is given a choice of joining one of five "Unions", after which a Dream Eater named Chirithy explains the player's role of destroying Heartless to collect Lux. Under Chirithy's direction, the player visits illusions of future worlds to carry out their mission. As they continue, Chirithy explains that the Foretellers have learned from the Book of Prophecies about a great battle in which the world will be consumed by darkness. To save the future, the Foretellers use the book's powers to project the future into their era, hoarding Lux to protect the world's light.
The player befriends Ephemer, a Keyblade wielder from a rival Union who wishes to explore the Foretellers' tower in the center of town. The player agrees to help, but Ephemer disappears shortly thereafter. Later, the player meets another wielder from Ephemer's Union named Skuld, who is investigating his disappearance. Exploring the tower, the player and Skuld are caught by Ava, who challenges them to a duel. Upon her defeat, Ava reveals that she is recruiting Keyblade wielders to the Dandelions, a group who will be sent to another worldline to keep them out of the impending war so they may rebuild the world in its aftermath. She explains that Ephemer is one of those chosen, and offers the same to Skuld and the player; Skuld accepts, but the player is uncertain. As time passes, other wielders accuse one another of stealing Lux, and the Foretellers – suspecting one among themselves to be a traitor – begin rallying more wielders to their Unions to bolster their forces for the coming war.
Seeking a solution, the player, Skuld, and Chirithy find Gula, who believes the only one who can stop the war is the now missing Master of Masters. Ava tracks down the Master's sixth apprentice, Luxu, who vanished to watch the war unfold as per the Master's instructions; believing Luxu to be the traitor, Ava attacks him, starting the war as prophesied. Skuld returns to the Dandelions while the player participates in the war alone, battling for as long as they can before collapsing in exhaustion. The war ends with the player as the sole survivor, reuniting with Chirithy, Skuld, and Ephemer before losing consciousness. Sometime later, Chirithy awakens the player and lies to them that the events surrounding the war were all a dream. Unbeknownst to them, Maleficent appears nearby – having traveled back in time after being defeated by Sora and his friends – and makes plans to conquer her world in the past.

''Kingdom Hearts Unchained χ'' / ''Union χ'' story

A series of flashbacks set before the Keyblade War depicts the Master of Masters giving Ava a list of five Keyblade wielders who are to become the new Union leaders. Under his instructions, she gives each of the chosen a special rulebook to follow, but defies his orders by giving one of them, Brain, a Book of Prophecies. Another of the new leaders, Strelitzia, secretly follows the player throughout their journey, being fascinated with them. As the war starts and she realizes the player is not a Dandelion, she tries to find them and convince them to join, but she is ambushed and killed by an unknown figure.
After the Keyblade War, the Dandelions reside in a datascape of Daybreak Town, with all but the Union leaders made to forget what had happened. In the real world, Ephemer meets with Skuld in the Keyblade Graveyard, revealing that they are two of the new Union leaders selected by Ava. They are met by three others: Ventus, Brain, and Strelitzia's older brother, Lauriam. The five agree to keep the world's destruction a secret and form a single Union, Union Cross, to prevent the past from repeating. Meanwhile, Maleficent encounters an unknown figure who explains that the world she is in is only a data simulation. Refusing to let her stay due to the damage her knowledge of the future could cause, the figure guides her to the tower in Daybreak Town, telling her to use the Ark at its center to return to her time.
Lauriam investigates Strelitzia's disappearance, aided by his fellow party member Elrena, before confronting Maleficent in the tower. Maleficent defeats Lauriam and escapes back to her time, but the Ark is damaged during the fight. Meanwhile, glitchy afterimages of events from before the Keyblade War begin appearing in Daybreak Town. With the player's help, Brain discovers the glitches are an effect of the datascape being forcibly connected to a data world that was never connected to the original Daybreak Town, and that they are now all trapped in the datascape. While searching the Book of Prophecies for a solution, Brain finds the Master's list and discovers that Ventus is not one of the intended Union leaders, suspecting that Ventus was manipulated into replacing Strelitzia.

''Kingdom Hearts Dark Road'' story

Xehanort, living bored on the Destiny Islands, is approached by Ansem, his Heartless from the future, and is shuffled through a portal to Scala Ad Caelum, a world where Keyblade Wielders are trained. Some time later, Xehanort, now a Keyblade Wielder, and his classmates Eraqus, Urd, Bragi, Vor, and Hermod are told by their master Odin that seven upperclassmen have gone missing before their Mark of Mastery exam, with the sister of fellow classmate Baldr among them. While they are far from ready, Odin tasks the youths to find the missing seven by scouring the many worlds.
Before they leave, Xehanort and his classmates discuss the state of the worlds: even long after the events of the Keyblade War, many fragments of the World are still forming, and those that have already formed flow on different timeframes — while one may be far in the future in terms of technology, another may be still in the beginnings of bearing life or basic technological advancements. With that in mind, and the order not to interfere in the affairs of other worlds, Xehanort and his friends begin their search, splitting into two teams. While they do not find traces of their friends at the end of the day, they remain resolute.
Four years later, Xehanort, having just put fresh flowers on four gravestones, says his goodbyes to Eraqus, stating he's going off on his own, to see what the master hasn't shown them. While Eraqus hates the idea, he isn't going to stop him, knowing that he'll be back since they need to settle the score for their games.

Development

Kingdom Hearts χ was co-directed by Tetsuya Nomura, one of the series' creators, and Tatsuya Kando, who had previous directed Nintendo DS game The World Ends with You. The game's music was composed by Yoko Shimomura, a regular contributor to the series' music. The game was co-developed by Square Enix and Japanese studio Success Corporation. Square Enix originally handled the planning and design itself, but due to their developers' inexperience with creating browser games, development was transferred to the Success Corporation, who were familiar with the process. Despite multiplayer elements being included, the game was "fundamentally single-player", as with most other entries in the series. Chirithy, the player characters' companion, was designed around the concept of a supportive yet unobtrusive guide. Nomura based the character's design on the Scottish Fold domestic cat.
Due to difficulties that arose adapting the core Kingdom Hearts experience into a browser game, the presentation was designed in a fairy tale-style instead of the locations encountered previously by series protagonists Sora and Riku. And because the game was to be played with a mouse instead of a game controller, the gameplay focus became simple controls and "flashy" battles. In an interview, Nomura stated that the work on developing Kingdom Hearts χ was paused for a time so developers could work on Kingdom Hearts III. He also stated that at the time they were exploring ways to allow more fans of the series to experience the game. The stories of Kingdom Hearts χ and Kingdom Hearts III were both written at the same time, and thus share a strong connection. Despite this strong link, it was described by Tetsuya Nomura as a title where story was not the focus, and that its content was completely separate from the main series, making it accessible for newcomers. The game's title refers to the χ-blade, the original Keyblade and a weapon central to the Kingdom Hearts storyline.
The creation of a mobile version of the game was decided upon while the browser version was still being developed. Nomura initially planned to release both titles simultaneously, with each being updated individually. However, as development went on, the team's efforts became focused on finishing Kingdom Hearts χ, and development on Unchained was halted. The original plan was to make the game a simpler version of its browser counterpart, but with the increasing specs of mobile devices, the workload increased, contributing to the halt to development. As mobile devices employ a different control set-up to web browsers, Unchained could not work simply as a port of Kingdom Hearts χ. Its title "Unchained" signified the gameplay and story of Kingdom Hearts χ being released into a mobile format. One of the changes instituted during the games mobile remake was to make the gameplay more "casual" than Kingdom Hearts χ, with battles being shorter and potentially easier.
In March 2017, ahead of the first anniversary of the North American launch of Unchained χ, Square Enix announced that the mobile game would be rebranded as Kingdom Hearts Union χ in April 2017. The relaunch of the title would include a new Union Cross multiplayer mode, allowing parties of up to six players to take on the Heartless together through the game's matchmaking feature as they communicate with each other through emotes and text options, and a theater mode to rewatch unlocked cutscenes and animations. In September 2018, a series of special "Classic Kingdom" minigames was added to Union χ; by completing certain objectives in these minigames, players were able to unlock a special "Starlight" Keyblade for use in Kingdom Hearts III.
In January 2020, a new mobile game called Kingdom Hearts Dark Road was revealed, being developed by the same team working on Union χ. It was later clarified that Dark Road would be a standalone game accessed within Union χ and that the app would be rebranded as Kingdom Hearts Union χ Dark Road upon Dark Roads release. Players would be able to access Dark Road without needing to meet certain criteria within Union χ and would have the ability to link the two games.

Release

The game was first announced at the Tokyo Game Show on September 20, 2012 alongside Kingdom Hearts HD 1.5 Remix under the tentative title Kingdom Hearts for PC Browsers. Its official title was announced in February the following year. To promote the game, codes for special items and in-game currency were included with first-print copies of Kingdom Hearts HD 1.5 Remix. A closed beta for the title began on March 22, 2013, with Beta recruitment beginning on March 13. The test was available for users who had a Yahoo Japan ID, and included in-game items and currency as a starting gift. An open beta test began on July 9, 2013, and the game's official service began on July 18 of the same year. Since the original release, the game received constant updates to its story missions, providing additional content to players. In April 2016, Square Enix announced that the browser game would be discontinued in September 2016.
Disney Interactive was forced to delay a western localization of the game when the game's publisher Playdom, a social game network owned by Disney, was shut down. Despite this, planning continued for a western release with playtesting taking place to improve upon the game before launch. The western localization was revealed to the public with the title Kingdom Hearts Unchained X at the 2015 Electronic Entertainment Expo. Unchained χ was released in Japan on September 3, 2015, in North America on April 7, 2016, and in Europe on June 16, 2016. Union χ became available on the Amazon Appstore for Amazon devices on January 29, 2019.
Kingdom Hearts Dark Road will be available worldwide on June 22, 2020.

''Back Cover''

In September 2015, Square Enix announced a new game entitled Kingdom Hearts HD 2.8 Final Chapter Prologue. The collection features Kingdom Hearts χ Back Cover, a 60-minute cinematic film that focuses on the Foretellers, elaborating on their actions during the events of the game and their attempts to determine who is the traitor among them. It was released in January 2017.

Reception

By September 2013, 200,000 users were announced to have enrolled for the game. During the 2013 WebMoney Awards, Kingdom Hearts χ was among the games voted into the "Best Rookie of the Year Good Games" category, with most voters praising the game for being accessible to series newcomers, and fun to play. Richard Eisenbeis of Kotaku was generally positive, saying that despite it being similar to other Japanese browser games and using a micro-transaction system, it was "an enjoyable little time waster."
Unchained was also well received, with Metacritic giving the game a score of 70 out of 100 based on 5 reviews. AV Club praised the game for being a true Kingdom Hearts title despite its free to play format. TouchArcade gave the game three out of five stars, praising the music and graphics while calling the gameplay shallow with an overcomplicated user interface. Gamezebo called the title "better than expected", citing the game's fun but simple combat and extensive character customization but critiquing the game's dialogue for being cheesy and the story for being weaker than the console Kingdom Hearts titles. In the month after it was released, the mobile version was downloaded over two million times.
