Story
After Ansem, Seeker of Darkness is defeated all worlds are restored, but there still ho sigh of King's return. Sora, Donald, and Goofy walk on the path on lush green field discussing where Mickey could be, when they see Pluto going somewhere. The trio start to chase him.

Pluto leads them to a crossroad. Not sure which path to take, a mysterious man in a black cloak approaches party and speaks to him, but his words are incomprehensible. The crossroads becomes one path and it leads trio to Castle Oblivion. The cloaked man appear before Sora, sampling his memories. After that, he tells party that in this castle "To find is to lose. And to lose is to find" and then gives Sora a card, which he create from boy's memory. The man explains to trio how to use these cards and then disappear in black portal. Sora then use the card to proceed through the castle.

The first world they go to is Traverse Town, where they discover that Leon, Aerith, Yuffie, and Cid have forgotten all about them. Strangely, though, they remember Sora, Donald, and Goofy's names, with Yuffie even mentioning that her heart still holds memories of them, even if her head doesn't. Leon gives Sora a tutorial on fighting and gives Sora a summon card, and the party then leave Traverse Town.

A second cloaked man appears and introduces himself as Axel. He challenges Sora to a fight but Sora fends him off and is given more World Cards, all of them sampled from Sora memories and thus resemble worlds he already visited previously. Sora, Donald, and Goofy go through each floor, they relive their memories from their first adventure, but all of them are somehow distorted in a different way. The party realise that their heads are being manipulated as they begin to lose their original memories. By piecing together their distorted memories, they eventually discover that a Nobody, Naminé, has been reorganizing their memories at the orders of Marluxia, the one who led them to the castle, in order to put herself in Kairi's place within Sora's memories and thus make him easy to control by the Organization XIII and Marluxia primarly. As the boy makes his way to the peak of the castle, Sora slays the Organization members Larxene and Vexen (although Axel is the one who puts an end to Vexen by blazing him out), as well as defeating the Riku Replica created by Vexen who has been progammed by scientist to be loyal to the Nobodies and later reprogrammed by Naminé to think that he's the real Riku.

Meanwhile, Riku chooses to reject the peaceful sleep of the Realm of Darkness and is pulled through a Corridor of Darkness to the basement of the castle. He makes his way through the castle with the assistance of King Mickey, while fending off the temptations of Ansem, who has left a piece of himself within Riku's heart and wants Riku to return to being his host again. Riku denies and go through the Castle's basements, repelling attacks from Vexen, Lexaeus, Zexion, and Riku Replica as well. The Organization wanted to use Real Riku as a weapon to counter Marluxia's use of Sora if he succeed in doing so. Along the way, Riku discovers that not all of Ansem's temptations were made by actual Ansem—some were instead made by DiZ, who was disguising himself as Ansem in order to test Riku's resistance to darkness.

Meanwhile, after another fight with Riku Replica, Naminé explains to Sora that his memories has been manipulated by her, and there's no such girl in his memories back on the Islands. Sora doesn't feel mad at Naminé for such intervenience and instead wants to punish the one who's responsible for these actions - Marluxia.

At the top of the castle, the 13th floor, Sora is ready to put an end to the rogue Nobody. After intense battle, Marluxia defeated by Sora's hands, making him fifth member of the Organization to die. Due to the damage done to Sora's memory, Naminé offers Sora a choise: to restore his memories, although it means he will forget everything in the castle or keep fake memories placed in him and leave Castle Oblivion right now. Sora asks Naminé to return the way that he was. Naminé agrees, but tells Sora that it will take a long time. Sora, Donald, and Goofy is ready to do this and go to rest in the capsules provided by Naminé.

The Riku Replica instead chooses to reject its given memories entirely, and leaves to find his own purpose. Desperate to prove that he is his own person, he is persuaded by Axel to slay Zexion in order to take his power and become something that the original Riku is not, but he is disappointed when it doesn't make him feel any different. Riku, following advice from DiZ to seek Naminé, runs into his Replica at the basement resembling Twilight Town. Enraged, the Replica challenges Riku to a mortal fight. Real Riku wins, and tries to comfort his suffering Replica as the latter fades away. Afterward, Riku finds Naminé and she quickly explain the situation about Sora and two are befriended each other. Naminé offers to manipulate Riku's memories in order to lock Ansem's phantom away, but Riku declines and instead chooses to confront Ansem directly. DiZ supports Riku, by giving him black coat so the Organization won't be able to track him down and also giving him a card to the last basement floor. When Ansem emerges from the basement, and Riku is ready to take him down. Boy manages to defeat part of Ansem's presense in him, but the dark power still lingers inside Riku.

After defeating Ansem, Riku and Mickey go to the crossroads outside of the castle, where DiZ appears once again to ask if Riku will be following the road to light or the road to darkness. Instead, Riku replies that neither suits him and choose the middle road. DiZ asks him is he takes road to the nightfall, to which Riku replies that he's not, and the road he chose is "the road to dawn".

A year later, Roxas waits on top of the clock tower at Twilight Town.

Gameplay


Kingdom Hearts Chain of Memories follows a totally new battle system as well as gameplay. The battle system now revolves around Sora's memories, represented as cards. Using these cards is the only way to attack. Map Cards are used to create rooms on each floor of the castle. What appears in each room depends on what card was used to generate that room. To obtain a map card you must defeat Heartless. Some map cards can only be obtained after getting further into the story for each of the different worlds.

Card Types

 * Attack cards - The most common way to attack, as the name suggests. These are depicted by different types of Keyblades and have red borders.
 * Magic cards - Unleashes magic spells, such as Fire, Ice, Thunder, Cure, and Gravity. These have blue borders.
 * Item cards - Used to restore attack cards or magic cards with Potions or Ethers, respectively. These can only be used once per battle, and have green borders.

Special Cards
There are three types of cards that are different from the other cards in battle:
 * Friend cards - Appear in the battlefield at certain times for pickup and can summon an ally to help fight. These have green borders, like Item cards.
 * Enemy cards - Based on enemies or bosses and can temporarily give Sora (or Riku) better offensive or defensive capabilities. These have black borders, and cannot be used in sleights.
 * Gimmick Cards - Gimmick cards only appear during certain boss battles. Unique attributes of these cards is that they are always green, the card value is always 0, and the picture on the card is a green Mickey Mouse insignia, like the keychain attached to the Keyblade. When used, the colors on the screen inverse, and the boss is either stunned, or the battle area changes allowing you to gain the upper hand. Due to their card value, they always break the enemy's attacks, and their effect prevents the boss from attacking until it is completed.

Standard Uses
Each card has a number from 0 to 9. This is known as Card Value. When a card is played against the enemy's card, the card with the lower value "Breaks" and is discarded. This leaves enemies vulnerable for a few seconds. Cards with a value of 0 can break any attack, but can be broken by any card if played too early.

Sleight
A special ability that can be either learned from leveling up or obtained from boss fights or chests. Some sleight examples are: Sonic Blade, Strike Raid, and Ars Arcanum.

Some of these sleights did not appear in Kingdom Hearts, such as Fire (Blizzard, Thunder) Raid, Homing Fira (Blizzara, Thundara), etc., as well as some friend sleights, such as Blazing Donald. Further sleights were added to Kingdom Hearts Re:Chain of Memories as well.

Combining Cards
Cards can be combined into sets of three, not only creating a higher value combo that is more difficult to break, but is also essential in activating sleights. The cost of combining cards is that the first card used in the combo cannot be reloaded when the deck is reloaded, although certain items, such as Elixir and Megalixir, can reload any unreloadable cards.

Sora's Gameplay
Sora can use any available card to create up to three decks as long as there is at least one attack card in his deck and the player doesn't exceed his Card Point (CP) limit. During Level Up's Sora can increase his CP, in addition to obtaining more HP and new sleights at certain times. Other than using Attack, Magic/Summon, and Items cards, Sora can also use Premium cards, which are special Attack or Magic cards. These cards do not require as much CP to equip although they can become unreloadable cards when used, with the minor exception as the second or third card in a combo. Other than using Moogle shops to obtain additional cards, Sora can also collect cards by smashing or jumping on objects, occasionally making a random card appear. There are certain cases where Sora has to earn the card through the storyline first before it becomes available in a Moogle Shop.

Room Cards
There are cards throughout the game that are used to open doors to different rooms once entering a certain world. They are in the same colors as the magic, item, and attack cards, except they are usually only gained at the end of a battle, and they generally only are used to open doors within worlds. They may have names such as Roulette Room, Tranquil Darkness, Feeble Darkness, Calm Bounty, Martial Waking, and even special room cards called Key to Rewards and many more. They are needed to open all doors throughout Castle Oblivion.

Reverse/Rebirth Mode
After completing the game as Sora, a new challenge arises. Reverse/Rebirth mode follows Riku as he climbs the basements of Castle Oblivion. Riku gets a World Card for each of the worlds Sora goes through except 100 Acre Wood. Riku's deck cannot be changed; however, it changes automatically as time goes on. Riku does not need as much time to reload his deck. Certain enemy cards are only available to Riku, and then unlocked for Sora after completing the game with Riku. Riku can only keep the enemy cards that are based on the bosses after winning them during battle, the others are available in one world only.

Riku's Gameplay
Instead of leveling up HP, CP or sleights, when Riku levels up, he can increase HP, AP (Attack Power), or DP (Dark Points). After Ansem, Seeker of Darkness (who is still alive) tempers the darkness in Riku's heart, Riku can use his dark powers during battle. These powers are triggered by taking damage or breaking his opponent's cards; when the Dark Points reach 30 or more, Riku will automatically go into Dark Mode. In Dark Mode, Riku can use 3 powerful sleights exclusive to his Dark Mode: Dark Aura, Dark Firaga, and Dark Break (these attacks were used by the Riku Replica in Sora's story). How long Dark Mode lasts depends on how much DP he has, and taking damage as well as being card broken reduces the amount of DP Riku has left in a given battle. When the DP counter reaches zero, Riku turns back into his original form. Dark mode can be achieved any number of times in a given battle.

Riku does not have access to any of the friend cards that Sora had. Instead, he has King Mickey as his only friend card. Using Mickey heals Riku, reloads the deck, and stuns enemies for a few seconds. Using more Mickey cards at once increases the power of this attack. Because of his inability of using magic cards, Riku cannot heal as easily during battle, limiting it to the Oogie Boogie and Search Ghost enemy cards in addition to Mickey Mouse. Bosses exclusive to Riku's story are: Zexion (Kingdom Hearts Re:Chain of Memories only), Lexaeus, and Ansem, Seeker of Darkness.

Link Mode
With the use of a, an additional multiplayer mode can be played, where two players battle each other. Decks are loaded from save files of Sora's story. The player controls Sora while the opponent is depicted as AntiSora, although the difference between the two is only cosmetic. Different worlds can be chosen to determine the arena's background. Both players can see each other's battle cards to some extent, though this effect can be blocked with the Darkball enemy card.
