Kingdom Hearts Birth by Sleep

Birth by Sleep is an action role-playing game with hack and slash elements that introduces a gameplay aspect to the series called the Command System. This system allows players to customize a Command Deck with techniques and abilities that they can perform at will, called Deck Commands. Performing ordinary attacks and Commands fills a gauge displayed above the Command Deck. When certain requirements are fulfilled and the gauge is full, the player's basic attack is changed to the "Surge" Command, which racks up powerful combos depending on the active Command Style. Filling the gauge a second time replaces the "Surge" Command with the more powerful "Storm" Command. Unlike previous games in the series, the game does not utilize Magic Points (MP) for spells or magic casting. It instead uses a system known as Focus, which is displayed in an orange gauge on the interface. The player can use Focus to perform a technique called Shotlock, in which they enter a first person mode to attack enemies with homing spells that differ with each character and technique, depleting the gauge relative to the number of enemies targeted. Once depleted, the Focus gauge gradually refills with every attack and Deck Command the player lands on an enemy. Another aspect introduced in the game is the Dimension Link (D-Link), measured in a blue gauge on the interface. It is used to draw power from certain companions who the player characters meet during the game, such as Experiment 626, temporarily replacing the commands in the player's customized command deck with a pre-determined set of commands that differ with each D-Link. Once the command gauge is filled while performing a D-Link, a powerful finishing move is activated to take out enemies. Each finishing move has two levels which can render a finishing move more powerful than before, similar to that of the Command System. The D-Link can only be used when its corresponding gauge is filled completely, and can be activated by pressing right on the directional pad to access the D-Link menu, followed by selecting the chosen ally. Scenarios The game is divided into three separate scenarios, with each one focusing on one of the three main characters: Terra, Aqua, and Ventus. While the first ten minutes of the story are the same regardless of the chosen character, the events that follow differ in each scenario, with each character's narrative occurring parallel to the others and intersecting with one another at different points. The recommended scenario order of play by Nomura is Terra, Ventus, then Aqua, as it allows the player to best understand the story. In each mode, players control one of the three main characters. In Versus, players fight against each other in a deathmatch-style game, while in Arena players fight co-operatively in a "Survival Mode" style of gameplay against waves of Unversed. Rumble Racing features players racing against each other competitively on their Keyblade vehicles, which can also be used to attack rivals. Command Board is a board game using the in-game Command Board mechanic, where players try to reach the end first as in traditional board games. Setting records in the Mirage Arena earns players medals which can be exchanged for rare items in-game. Only Ad-Hoc wireless multiplayer, where all of the players need to be physically near each other, is allowed. ==Plot==

Setting Birth by Sleep is a prequel set ten years prior to the first Kingdom Hearts game. Like other games in the series, the player progresses through a collection of various worlds, based on various locales from the Disney animated features canon: Dwarf Woodlands (Snow White and the Seven Dwarfs), Enchanted Dominion (Sleeping Beauty), Castle of Dreams (Cinderella), Olympus Coliseum (Hercules), Deep Space (Lilo & Stitch), Neverland (Peter Pan), and Mysterious Tower (Fantasia). As with the Heartless in Kingdom Hearts and the Nobodies in Kingdom Hearts II, Birth by Sleep introduces a new type of enemy: the Unversed, "fledgling emotions" that are "not well-versed in their own existences" and feed on negativity. As with other games in the series, Birth by Sleep features an extensive cast of Disney characters. As Birth by Sleep is a prequel to the first Kingdom Hearts, the staff decided to add Zack since he is the protagonist of the Final Fantasy VII prequel, Crisis Core: Final Fantasy VII. Story Master Xehanort brings a comatose Ventus to the Destiny Islands after his heart is damaged; a newborn heart senses Ventus's heart and connects with it, saving him. Years later, at the Land of Departure, Terra and Aqua take an exam to achieve the Mark of Mastery. Xehanort manipulates the exam so Terra fails while Aqua passes, lessening Terra's control of the darkness in his heart. Shortly afterward, Xehanort disappears and a horde of Unversed appear throughout the worlds. After learning about these developments from Yen Sid, Eraqus sends Terra and Aqua to travel across the various worlds to destroy the Unversed and find Xehanort. Meanwhile, Vanitas convinces Ventus to follow Terra against Eraqus's wishes, while Eraqus orders Aqua to monitor Terra's darkness and retrieve Ventus. As the three travel through several worlds, Terra attracts the attention of villains who offer him Xehanort's whereabouts in exchange for assistance in their own agendas. He eventually finds Xehanort, who urges him to use his inner darkness to gain power. Xehanort further instructs Terra to destroy Vanitas, the source of the Unversed, who was created from the darkness extracted from Ventus's heart. The three friends briefly reunite at Radiant Garden, but a schism forms between them when they argue over Terra's presumed actions and Aqua's espionage. Ventus encounters Xehanort, who reveals his intention to recombine Ventus and Vanitas's hearts to create an all-powerful Keyblade called the χ-blade. Xehanort sends Ventus to the Land of Departure to confront Eraqus, who attempts to destroy Ventus to foil Xehanort's plan. Terra arrives to save Ventus and duels Eraqus; upon Eraqus's defeat, Xehanort vanquishes him and enshrouds the Land of Departure in darkness, telling Terra to go to a world known as the Keyblade Graveyard. Ventus is instructed to do the same by Vanitas, as is Aqua by Yen Sid upon being informed of Eraqus's demise at Xehanort and Terra's hands. Terra, Aqua, and Ventus reunite at the Keyblade Graveyard, where Xehanort and Vanitas reveal their plan to use the χ-blade to unlock Kingdom Hearts and start a Keyblade War, an apocalyptic event that nearly destroyed the world in the past. Terra's heart is consumed by darkness in the ensuing battle, and Xehanort takes over his body to replace his own aging one. However, Terra's mind remains within his discarded armor, which comes to life as the Lingering Will and defeats Xehanort. Meanwhile, Ventus is forced to fuse with Vanitas to create the χ-blade. Aqua and Mickey fight the possessed Ventus and destroy the χ-blade, while Ventus defeats Vanitas in a metaphysical battle within his own mind, but loses his heart and falls into a catatonic state as a result. After learning of Ventus's condition from Yen Sid, Aqua puts his body in stasis at the Land of Departure, which she transforms into Castle Oblivion. At Radiant Garden, Aqua battles the possessed Terra. When Terra struggles for control of his body, Xehanort impales himself with his own Keyblade, causing him to sink into the realm of darkness. Aqua dives into the realm and rescues Terra, but becomes trapped in the process. Ansem the Wise finds an amnesiac Xehanort still possessing Terra's body, while Ventus's heart merges with that of a young Sora, the newborn who had previously saved him on the islands. In the game's secret ending, Aqua meets Ansem in the realm of darkness and learns from him about Sora, who has the power to save those connected to his heart. Sora has learned of Terra, Ventus, and Aqua's fates from a letter sent by Mickey and undertakes another quest to save them. ==Development==

Development of the game began in June 2005 and was originally intended for the PlayStation 2 with Sora as the prototype protagonist of the game. Birth by Sleep was developed by Square Enix's fifth Product Development Division, based in Osaka, During development of Kingdom Hearts II, the Osaka-based team had requested to be involved in a spin-off if one were to be made. Nomura has referred to the game as "Episode 0", saying that the game is on the same scale and plays as big an importance as Kingdom Hearts and Kingdom Hearts II. Early during the game's development, Nomura already had various scenes in mind such as Terra's and Riku's conversation in order to explain the latter's ability in the original games. Various parts from the plot had to be modified to make the game more light-hearted such as Eraqus' death at the hands of Xehanort after being defeated by Terra, how Aqua's scenario was supposed to end with her already trapped in the Realm of Darkness, and the relationship between Ventus and Sora. The Disney worlds were chosen to expand the characters of the Princesses of Light as well as Maleficent's who are connected with the events of the first Kingdom Hearts game, while the worlds of Neverland and Deep Space were chosen to add variety to the game, and Olympus Coliseum was selected to reflect the game's earlier setting compared to the original Kingdom Hearts. Birth by Sleep was directed by Nomura and co-directed by Tai Yasue. New trailers were shown at the 2008 Jump Festa in December 2007 and the DKΣ3713 Private Party, an invite-only event by Square Enix for fans, in August 2008; a playable demo was also available at DKΣ3713. The June 5, 2009 issue of Famitsu covered an interview with Tetsuya Nomura, where he said that the game was, at the time, at the voice recording stage. Nomura also confirmed in an interview that Birth by Sleep would contain a secret ending like in Kingdom Hearts and Kingdom Hearts II for the next game in the Kingdom Hearts series, which he confirmed to be a main game and the one which Nomura stated would link up Birth by Sleep, 358/2 Days, and coded. He also confirmed that a Birth by Sleep demo would indeed be playable at the 2009 Tokyo Games Show together with a new trailer. As with coded and 358/2 Days, Yoko Shimomura, the series' main composer, composed the most prominent themes, while the rest was created by other composers. Like Kingdom Hearts and Kingdom Hearts Re: Chain of Memories, Birth by Sleep uses Hikaru Utada's theme song "Hikari" for the Japanese version and its English version, "Simple and Clean", in the other releases. The game made its final public appearance before its Japanese release at Jump Festa 2010 on December 19, 2009, where a playable demo as well as new footage from the game were present and shown. Like previous console titles in the series, the game contains a secret movie at the end, which had been described as being more like a "true ending" rather than a teaser for the future like previous ones. Development of the movie began in October where Nomura noted in the blog that the game would contain a teaser to the next major Kingdom Hearts game similar to the teasers in previous games in the series. ==Reception==
