A remake of the game, Tales of Hearts R, was released on the Vita in March 2013 and later released in western regions in November 2014. Hearts R was also ported to iOS and released in Japan in October 2013 although it was pulled from the App Store on March 31, 2016, and therefore no longer available for download.

When Kohaku is attacked by a mysterious antagonist named Incarose and infected by a monster called a xerom, Kor attempts to cure her using his Soma, an ancient weapon designed to fight xerom. In the process, he ends up shattering Kohaku's Spiria, the essence of her heart and emotions, and scattering the pieces across the world. Together with Hisui, Kor sets off with Kohaku on a quest to restore her Spiria. Its characteristic genre name, a concept used extensively in the Tales series, is . It represents the game's central theme of people's hearts uniting to overcome strife. For Hearts R, extra story scenes were created and the genre name was altered to .

The remake was mostly handled by different development staff, but the writer and character designer both returned to add new content. Both versions of the game have received strong sales and highly positive reviews in Japan, with the DS version selling 260,000 units by 2009. Reviews of the DS version have been positive overall, while western reviews of Hearts R have been mixed to positive.

Gameplay

Like previous entries in the Tales series, Tales of Hearts is an action role-playing game. The game is split into two main areas: the field map and battlefield arenas triggered upon encountering an enemy. The battle arenas are fully rendered and played out in 2D. Characters are rendered outside pre-rendered cutscenes as 2D character sprites against 3D backgrounds. For the original Nintendo DS version, the top screen shows the main visuals, while the bottom screen shows the navigation map and other functions. Battles are triggered by running into enemy sprites rather than appearing as random encounters. As with previous titles, Skits, extra conversations between characters, are available for the player to trigger.

The battle system is a variant on the Linear Motion Battle System (LMBS) from multiple Tales titles: an action-based combat system similar to a fighting game: button commands instantly trigger various attacks and actions, and different attacks string together to form combos. The system used in Hearts is called the "Combination Aerial LMBS". Up to three characters participate in battle, with one controlled by the player and the other two controlled via artificial intelligence. The two AI characters be assigned to perform different actions such as healing or attacking. The "Combination" element refers to a special gauge that fills up and can be used to perform special attacks with party members not assigned in battle. A second "Emotion" gauge determines how many moves a character can perform: the gauge fills while the character is blocking, and is depleted by performing actions. The lower the gauge is, the lower a character's defenses are. Characters can employ special attacks called "Combination Blasters," Hearts take on the series' staple Mystic Artes ("Hi-Ougis" in the Japanese version). Defeated enemies drop items and materials that can be used to level up character abilities, with certain combinations of items yielding certain abilities and skills. Once enough skills have been learned, a character's weapon can be upgraded via three separate skill trees, with the abilities and power of the character changing according to the choice of skills beforehand.

For the PlayStation Vita remake, the gameplay takes place in 3D environments with fully rendered character models. Along with including a fourth AI-controlled character in battle, Hearts R uses a redesigned battle system titled the Aerial Chase Linear Motion Battle System (called "Arc Chase" in the Japanese version). The "chase link" mechanic enables a character to follow an enemy after knocking it into the air and continue a combo attack. By selecting an ally at the right moment, the player character can perform a Chase Cross attack, while holding down the attack button activates a finishing move. Multiple items found in chests scattered across the land can be used in battle (such as curative items) and for obstacles and objects in the field areas. Multiple elements from the series, including cooking healing recipes, are included. Random encounters with enemies on the field are also present. Characters level up using Soma Build Points (SBP), with the "soma" being a character's signature weapon and points causing the Soma to evolve, granting new abilities. SBPs are assigned to character stat values called Spir Parameters, which strengthen different character stats. Mystic Artes from the original game are carried over, along with new ones. Also added are Union Artes, special attacks unique to a particular character pairing. Characters can be assigned special accessories called "Combo Commands": activated by a specific set of button presses, the accessory grants a character full access to all their Artes for a limited time.

Story

Setting Tales of Hearts is set on the worlds of OrganicaCelland in Hearts and the Japanese version of Hearts R and MineraQuartzia in Hearts and the Japanese version of Hearts R (known to Organicans as the "white moon"), with the events of the story mostly taking place on Organica. Two millennia before the present day, Minera was in a state of war with itself, and Organica's inhabitants were used by the Minerans as a food source for organic weapons called xeroms. The xeroms were designed to attack Spirias, the crystalline essence of a person's emotions, and either destroyed them or infected them with an ailment known as despir. Some Minerans who sympathized with the Organicans' plight and wishes for peace provided them with weapons to fight off the xerom, called Soma.Lithia: Eons ago, the Mineran race flourished, boasting a culture highly skilled in the use of Will artes. But such prosperity led to greed and decadence, and our weak Spirias soon turned against each other. During the course of the unending Will artes war, a weapon was born. / Ines: The xeroms! / Lithia: Yes. Xeroms were engineered to be living weapons that fed off Spirias in order to fuel their monstrous evolutions. Though primitive, you Organicans boasted powerful Spiria, which attracted the attention of we Minerans. / Hisui: So you decided to turn people from our world into xerom chow. / Lithia: We invaded your planet and enslaved your ancestors to power the xeroms' evolutions. [...] No words can express my profound regret. However, know that some among us were gentle souls who detested these actions. My elder sister Fluora was one such person, and she dedicated her life to ensuring peace between realms. She created the Somas and the fortress of Mysticete so that we might be able to bridge our Spiria. In the present day, after Minera was destroyed, the xerom continue to threaten the people of Minera and the people who bear Somas and fight the creatures are called Somatics. Other remnants of the Mineran civilization left on the planet include the airship fortress Mysticete, mostly known to the Organicans as the "Forest of Thorns", and mechanoids, machines with synthetic Spirias who acted as guardians to important Minerans. During the events of Hearts, Organica is under the united rule of the Maximus Empire, which waged a war against the world's other factions eighteen years before in a conflict called the "Unification War".
