Kingdom Hearts Birth by Sleep

Kingdom Hearts Birth by Sleep is a Kingdom Hearts game for the Sony Playstation Portable. It was released in Japan on January 9, 2010, and it will be released in Summer 2010 for North America. The game's name is shared with the secret video at the end of Kingdom Hearts II Final Mix ("Birth by sleep"), which depicts a stylized version of a scene from the game. Kingdom Hearts Birth by Sleep was developed by the same team that created Kingdom Hearts Re:Chain of Memories. Like Kingdom Hearts and Kingdom Hearts: Chain of Memories, the main theme song for the game is "Simple and Clean", performed by Utada Hikaru. This game is the sixth in the series to be released, but is first chronologically.

Story
Kingdom Hearts Birth by Sleep begins in the Land of Departure, where three Keyblade wielders and close friends—Terra, Aqua, and Ventus (more commonly known as Ven)—train to become Keyblade Masters under Master Eraqus. To achieve this rank, apprentices must take the Master Qualification Exam once they come of age. Terra and Aqua take this test together, but while Aqua passes the test, Terra is deemed unfit to become a Keyblade Master due to the abundant darkness in his heart. Afterward, a group of mysterious creatures called the Unversed begin to surface in other worlds, and another Keyblade Master, Xehanort, disappears without a trace. Terra is sent to destroy the Unversed and find Xehanort, who had earlier encouraged him to embrace the darkness in his heart if he desires the strength to become a Keyblade Master. Ven, meanwhile, is goaded into following Terra by Xehanort's mysterious apprentice Vanitas, against Eraqus's wishes. Aqua is dispatched by Eraqus to survey Terra and keep him from falling into darkness, as well as to bring Ven back to the Land of Departure.

Upon arriving in other worlds, Terra, Aqua, and Ventus encounter various Disney characters, new and old, fighting off hoards of Unversed along the way. Among the characters they meet is Mickey Mouse, apprentice of the sorcerer Yen Sid, who is also on a mission to destroy the Unversed. Terra ends up attracting the attention of several Disney villains, who offer him the whereabouts of Master Xehanort in exchange of assistance for their own dark agendas. Terra reasons that Xehanort is after the seven Princesses of Heart—maidens who lack darkness in their hearts—and encourages Aqua to help them strengthen the light in their hearts, hoping it will draw Xehanort out. However, Aqua and Ven grow increasingly concerned for Terra when they hear rumors of him committing sinister deeds throughout other worlds. The three briefly reunite at Radiant Garden, where Aqua meets Kairi, a young girl containing a strong and pure light in her heart, and helps strengthen her light. Aqua and Ven also confront Terra, who distances himself from them to keep them out of the way of his increasingly dangerous dark powers. Terra and Aqua try to convince Ven to return to the Land of Departure, but he refuses until he is certain Terra won't fall into darkness.

Terra and Aqua eventually find themselves at Destiny Islands where they encounter two young boys, Sora and Riku. Terra sees potential within Riku and deems him worthy of one day wielding the Keyblade, while Aqua senses strong ties with Sora and Riku to Ven and Terra, respectively. Ven, meanwhile, comes across Master Xehanort, who reveals his intentions to use Ven's heart to create a final Keyblade known as the Χ-Blade, something Xehanort says Master Eraqus had known all along. Ven returns to the Land of Departure to confront Eraqus, who tries to erase Ven to prevent Xehanort's plans from succeeding. However, Terra, who had been sent there by Xehanort, misinterprets the situation and attacks Eraqus, teleporting Ven to safety. As soon as Terra realizes his error, Xehanort kills Eraqus and tells Terra to go to the Keyblade Graveyard, leaving the Land of Departure to be tornadoed by darkness. At Destiny Islands, Ven once again encounters Vanitas and learns of his hazy past: Ventus was once Xehanort's apprentice, but his heart was deemed too frail for Xehanort to use him as he intended, so he extracted the darkness in Ven's heart and used it to create Vanitas. As with Terra before him, Ven is instructed by Vanitas to go to the Keyblade Graveyard. Aqua, in the meantime, learns of Eraqus's death from Yen Sid, who tells her to go to the Keyblade Graveyard as well.

Terra, Aqua, and Ventus gather at the Keyblade Graveyard, where the remains of the mysterious Keyblade War are found. Master Xehanort appears with Vanitas and reveals his plan to use the Χ-Blade to unlock Kingdom Hearts and unleash the forbidden secrets of the Keyblade War onto the various worlds, as well as to use Terra's body as a new vessel for his own heart so that he may survive long enough to see his plans come to fruition. An epic battle ensues, with Xehanort freezing Ven, and Vanitas knocking Aqua unconscious. In his rage, Terra unleashes the darkness in his heart, inadvertently allowing Xehanort to unlock his own heart and successfully transfer it into Terra's body, which resulted in the birth of Xehanort. However, Terra's soul continues to linger in his discarded suit of Armor, which comes to life and defeats Xehanort. Ven, meanwhile, manages to thaw himself before Vanitas can kill Aqua, and discovers his dark counterpart to be the source of all Unversed. Vanitas merges with Ven, possessing him and creating the Χ-Blade. Aqua awakens under Mickey's care, and the two fight the possessed Ventus while he battles Vanitas from within. Aqua shatters the Χ-Blade as Ven destroys Vanitas, though Ven's heart is lost in the process. The destroyed Χ-Blade unleashes a burst of light, which consumes everyone present and scatters them to the corridors of space, save for Terra's Lingering Sentiment, which remained in the Keyblade Graveyard.

Mickey saves Aqua and Ventus and brings them to Yen Sid's tower, where Aqua learns that Ven has fallen into a deep sleep and will not awaken until his heart returns. Aqua brings Ven back to the ruins of the Land of Departure, where she discovers Master Eraqus's Keyblade and uses it to unlock the Chamber of Waking and create Castle Oblivion from the ruins. After leaving Ven within the chamber, Aqua goes to Radiant Garden where she encounters Xehanort still in Terra's body, but having lost some of his memories. Aqua then battles Xehanort who attempts to unlock his own heart again losing his memories completely in the process. Soon after, Terra's body starts sinking into darkness, but Aqua dives into the darkness and saves Terra from disappearing. She ends up getting trapped in the Realm of Darkness and beginning a journey to return to her friends. Xehanort is discovered by Ansem the Wise, ruler of Radiant Garden, and goes on to become his apprentice. Finally, Ventus's wandering heart finds its way to young Sora, merging with the young boy's heart.

An unlockable secret ending shows Terra and Master Xehanort lying dormant in Xehanort's body, waiting to see which will control it in the end, with Eraqus's heart revealed to be sealed within Terra. Shortly after the end of Kingdom Hearts II, Aqua encounters Ansem the Wise in the Realm of Darkness. Ansem, who had survived the explosion of his Kingdom Hearts Encoder with few of his memories remaining, reveals to Aqua that while darkness threatens to swallow the worlds again, hope lies in the form of Sora, who prepares to set out on another journey to help all of those whose hearts are connected to his.

Scenarios
The game is divided into three separate scenarios, with each scenario surrounding an individual of the three main characters: Terra, Ven and Aqua. The gameplay of each scenario differs based on the personalities and abilities of each character such as power, speed and magic. Players are able to choose which of the three scenarios to begin with and are able to switch to another scenario, midway through playing a scenario. Each character's story will take about fifteen hours, hence the total amount of gameplay hours would be forty-five hours (excluding deck-editing and retries), making Kingdom Hearts Birth By Sleep the longest game in the series to date.

Abilities
Kingdom Hearts Birth by Sleep features several new abilities, such as Deck Commands, Shoot Locks, and Mode Changes. Each are triggered via the battle menu. Deck Commands are the standard abilities, equipped via the menu with a certain cool-down time similar to the deck system of Kingdom Hearts Re:Chain of Memories. Shoot Locks are unique attacks that involve precise timing to unleash a dangerously powerful assault on an enemy. Mode Changes are even more deadly abilities that are unique for Terra, Ventus, and Aqua, just like the Shoot Lock.

Command Board
Besides leveling up the normal way in the other games in the Kingdom Hearts series, players can also play on the Command Board, where they can land on special squares in a system similar to a game of Checkers or Chess in order to gain special prizes, certain boxes summoning Disney characters or having other effects.

D-Link
Past Kingdom Hearts games have allowed the player to summon unique Disney or Final Fantasy (only in Kingdom Hearts: Chain of Memories) characters to their sides, each with their own abilities and usually not encountered anywhere else in-game. Kingdom Hearts Birth by Sleep views this ability in a new light, via Dimension Links (shortened to D-Links), which grants the wielder the powers of a unique character for a short time. Wireless D-Links are also possible, allowing a player to connect with a friend's PSP to summon their character to the friend's side. D-Links have their own menu, and are each granted a special ability, summoned via the battle menu.

List of D-Links

 * Cinderella
 * Snow White
 * Experiment 626
 * Zack
 * Mickey Mouse
 * Peter Pan
 * Donald Duck
 * Goofy
 * Terra
 * Ventus
 * Aqua
 * Maleficent
 * Vanitas

Multiplayer Mode
Like its predecessor, Kingdom Hearts 358/2 Days, Kingdom Hearts Birth by Sleep contains a multiplayer mode known as Joint Struggle. While only a differently colored armored form Terra, Aqua, and Ventus are playable, new abilities are usable only through this mode, and players can obtain bonuses for use in Story Mode. Up to three players can battle Unversed with customized names. They will also be ranked, this rank demonstrated by colored symbols that look like those Terra, Aqua, and Ven wear. A new world known as the Mirage Arena is also only accessed via the Joint Struggle. You can also play on the Command Board in multiplayer mode with a specific Mirage Arena game board.

A New Enemy
As Kingdom Hearts Birth by Sleep is a prequel to the first Kingdom Hearts, and incidents with Ansem the Wise and the Heartless have yet to happen, Nobodies yet to be created, a new enemy known as the Unversed fills this gap. Ranging from very small Shadow-like creatures to large monstrosities like the Wheel Master, they attack Terra, Ventus, and Aqua along their journeys to countless worlds.
