Kingdom Hearts Chain of Memories

Kingdom Hearts: Chain of Memories is a Game Boy Advance sequel to Kingdom Hearts. It was published by Square Enix and developed by Jupiter, and was released in 2004. It is the second game of the series and the third game of the timeline after Kingdom Hearts Birth by Sleep and Kingdom Hearts.

Story
Sora, Donald and Goofy walk down a long path that seemingly goes nowhere. They see Pluto and start to follow him. He leads them to three paths. While deciding which path to take, a mysterious man in a black cloak approaches Sora and speaks to him, but at that moment his words are incomprehensible. The path becomes one and it leads them to Castle Oblivion. The cloaked man appears as they enter the castle and gives them a card. They 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, yet they strangely remember Sora's, Donald's, and Goofy's names, where Yuffie comments, "You're not in my memory, but my heart remembers you." After Leon gives Sora a tutorial on fighting, they leave Traverse Town.

The man appears once more after they arrive on the next floor. Another cloaked man appears and introduces himself as Axel. Sora battles him and when defeated, Axel gives him more cards, disappearing soon after. Sora, Donald, and Goofy go through each floor, experiencing their memories, among the castle floors. They start to lose their memories. A Nobody named Naminé begins to replace memories of Kairi with fake ones of herself. It turns out she is good and is manipulating his memories under the orders of the head of the castle, Marluxia. This escalates to a final battle in the end, for Sora's life, and Naminé's freedom.

Meanwhile, Riku awakens down in the castle, and as he goes up the basement levels of Castle Oblivion, he must take control of the inner darkness inside of him, dealing with Xehanort's Heartless, the Riku Replica, and three members of Organization XIII, Vexen, Lexaeus, and Zexion, along the way.

Sora's Story
Sora's Tale I

''Our friends may be here... ''

It was that thought that led us to Castle Oblivion, where cards rule over all.

''A mysterious man gave Sora a card, using it to took us to Traverse Town--of all places! ''

''It turned out the town was just a figment of our own remembrances, the first world of many that lie in Sora's heart. ''

''And so our journey through these worlds begins. ''

Sora's Tale II

''It seems we're slowly losing our memories of what happened before the castle. And all my notes about the last journey have vanished!''

But in exchange, Sora is remembering other things he must have forgotten until now--like a girl he knew when he was little.

While fighting Larxene, Sora finally remembered the girl's name...

''Naminé. ''

Sora's Tale III

''Sora pressed on in his search for Naminé, and can you beleive it? He found Riku, his best friend whom we thought was lost.''

Sora was so happy, but Riku attacked him just like that, saying, "I'll protect Naminé!"

''What could he mean? Will something happen if Sora finds Naminé?''

Sora is chasing after Riku...and the answers.

Riku's Tale
Bored with his secluded island life, Riku dreamt of seeing other worlds.
 * Riku's Tale I

He got his wish when darkness devoured Destiny Islands and he was thrust into the outside world.

While looking for his lost friend Kairi, he met Maleficent, and accepted her help.

''But Maleficent had her eyes on Riku's strength and was working to make him her underling. She gave Riku the power of darkness, but as he used it, it gained power over him.''

This is why Riku fought his best friend, Sora, and how his heart fell to Ansem, pursuer of darkness.

''But Riku was freed by Sora's light. Riku, Sora, and the king worked together to close the door to darkness, but Riku was trapped inside, in the realm of darkness.''

Will he see the realm of light again?

Led by a mysterious voice, Riku made his way through the card-worlds, but met only dark beings within.
 * Riku's Tale II

Riku was told that because he rejected the other things in his life to claim darkness, his heart is now devoid of anything but the darkness he sought.

Unable to accept this, Riku encountered Ansem, who tried yet again to conquer him.

The king intervened to save Riku, but Ansem had not let go of his heart.

And so Riku must fight the darkness within.

Embattled with the darkness in his heart, Riku met someone who looked just like him, a replica crafted by Vexen, a member of the Organization.
 * Riku's Tale III

The replica commanded darkness freely, and called Riku cowardly for shunning the dark.

''Meanwhile, agents of the Organization laid their rivalry bare. Sora and Riku seem to be the reason they control the castle—but why?''

Vexen took his replica of Riku and headed for the surface, but finally fell at Sora's hands.
 * Riku's Tale IV

Lexaeus confronted Riku, intending to bring him to submission using all force necessary.

''It was then that the powerful darkness in Riku's heart awakened. The darkness defeated Lexaeus, then dragged Riku into the realm of darkness.''

There, Ansem's shadow loomed large, but Riku was again saved by the king's light.

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, Cure, Gravity, etc. 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 two 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 off of 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.
 * Trick Cards - Trick 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.

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
Main article: Sleight

A special ability that can be either learned from leveling up, or obtaining them from boss fights or chests. Some sleight examples are: Sonic Blade, Strike Raid, and Ars Acarnum. Some of these sleights did not appear in KH1, such as Fire (Bizzard,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. For more info on the game, search it in this wiki. For more info on sleights click the link above.

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 you don'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 the doors within world. 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.

Worlds
This is the only world that is actually visited during Chain of Memories, as all other worlds are merely recreations - based on Sora's and Riku's memories - inside the castle.
 * Castle Oblivion

Memory Worlds

 * Traverse Town
 * Wonderland
 * Olympus Coliseum
 * Agrabah
 * Halloween Town
 * Monstro
 * Atlantica
 * Neverland
 * Hollow Bastion
 * 100 Acre Wood
 * Twilight Town
 * Destiny Islands

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 off of 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 Xehanort's Heartless (who is still alive) tempers with 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 exceed 30 or above, 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.

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 (Re:CoM Only), Lexaeus, and Xehanort's Heartless.

Kingdom Hearts Re:Chain of Memories
Kingdom Hearts Re:Chain of Memories is a Playstation 2 remake released in a package along with Kingdom Hearts II Final Mix. The game features 3-D graphics and voice-acting, along with all-new cards and cutscenes. It was released in North America on the 2nd of December, 2008.

Trivia

 * In Kingdom Hearts Re:Chain of Memories, when Jiminy declares that all the pages in his journal were erased and that each page is blank, if players look closely, there is an entire page filled with random scribbles that represent words. This may be the mysterious page from Kingdom Hearts coded.
 * In Japanese, Reverse and Rebirth are homophones.
 * By holding down you can enable an event skip feature.
 * In Kingdom Hearts: Chain of Memories, Monstro and the 100 Acre Wood are the only worlds with minigames (Monstro is a battle oriented world though).
 * According to director Tetsuya Nomura, the game was originally going to be called Kingdom Hearts: Lost Memories.
 * Even though a trick card is a 0, the easiest card to break, a boss will never use a card to break it, as it freezes time.
