➤ The complete solution of Kingdom Hearts: Chain Of Memories 🕹

Please note:

The solution is based on the American version of the game, so it is possible to find differences for the Spanish version.

After the opening cutscene and the dialogue about where the king is, a figure in black will appear telling you that you have lost your powers and will introduce you to the card combat mode. Shortly after you can choose the world to visit, choose the only one possible which is Traverse Town.
Once you arrive you will discover that you are alone and stuck in this area, immediately afterwards the battle will begin (Tutorial) and at the end the mysterious figure will speak to you again and you will be able to learn the other techniques of the cards (quite intuitive) and how to change them and finally you will discover that with the Select button you can manage your cards.
After the scene with your two friends you can move the character again, hit the door with the key and choose the right card to continue and thus begin your wonderful adventure.

First floor: Traverse Town

The first room will have no enemies but only a black diamond which if touched will save your game, immediately afterwards a barrel will fall which if destroyed will give you a card and then an enemy will appear and you will have to beat him. Remember during the battle to collect both the blue orbs for the experience, both the cards that the enemies will drop. Now go on and hit the door with the key and then use the right card to pass (I don't say that anymore, it's always the same thing).
In the new room you will have to kill all the enemies before receiving the card that will allow you to continue in the upper door, in the third room there will be two doors, you after killing all the enemies (it is not mandatory but doing experience is essential ) go to the door on the left and go through to get to the fourth room (here you will have to use a special card you will have).
Take your friends' cards and then talk to Leon and Yuffie, Leon will eventually learn you a new battle technique. Listen to the instructions and you will learn the combos, very useful in battle. After the battle Leon will give you a precious gift, the special Simba card.
You will return to the previous room and the door you just passed will be gone, kill everyone again and then go through the door at the top.
Another scene this time with Yuffie and Aeris and at the end of the dialogue you will receive another special card, go back and enter the top door to continue the adventure. Eliminate the enemies and then go through the door on the left with the green card you now have. Another conversation this time with the legendary Cid Highwind (for Final Fantasy fans since the first legendary episode) and in the end you will see it with a nice Boss.

BOSS 1 : Guard Armor Boss di Traverse Town

Victory Award: Guard Armor Card

Easy this Boss taken directly from the first Kingdom, hit the enemy and remember to take all the Mickey Mouse cards you see to block the monster and be able to attack it more easily, first destroy the legs and then take care of the arms, only after you have it abundantly handicapped you can take care of the body, watch out for its attacks in running and jumping which are quite powerful. After destroying it, take the experience and its card and you will return to talk to Aeris, after the conversation you will be in another room.
Here, go up to save and then take the door nearby to return to the Castle.

Cloud's attacks are only via combos so you can prevent them quite easily, remember that if you are hit it will take away a lot of energy (the sword hurts). However you will see that there will be no problems, Cloud's slowness will allow you to attack him without taking big risks.
In the third special room there will be the Boss and here the trouble begins.

BOSS 6 : Hades Boss del Colosseo

Victory Award: Hades Card

This is one of the toughest bosses in the game. You must have a level of 20 or more to beat him and your card level must be high because otherwise you will never be able to attack him. Hades can be either blue or red, if he is blue there is no problem because he has only one type of attack, a beam of fire that is easy enough to avoid.
The problems come when it turns red where the attacks become three and are very dangerous, the hands of fire take away energy but can be avoided, then the flamethrower when it throws fire from your hands (stay away from it because it hurts a lot) and finally the easily avoidable fireball.
Always move and attack him when he is in blue, when he is red use the hit and run technique, after beating him you will receive the Cloud Card, very useful later.

BOSS 7 : Parasite Cage

Victory Award: Parasite Cage Card

He would be a difficult Boss if he didn't have a weak point to fully exploit: Fire. The Boss has three attacks, a sphere of energy, a direct physical attack (it comes on you) and then a short attack where it randomly hits the ground with its tentacles.
The simple trick is to hit it with fire, this will paralyze the enemy and you can attack him without problems, you will also receive the Mickey Mouse Card that will allow you to fly towards the monster. Beware of the green liquid which if stepped on too much will harm you.
After beating the Boss you will find Pinocchio and you will receive the Golden Card to continue.

This is a simple battle and without great difficulty, in fact the Boss before attacking you will let himself be hit, use the most powerful combo you have and be very careful to flee as soon as it's finished because his shot will paralyze you for a few seconds. Watch out when reloading because you will be vulnerable, move a lot and soon the Boss will flee. When that happens, go up the stairs to the next floor.

BOSS 13: Malefica Boss di Hollow Bastion

Victory Award: Maleficent Card

Maleficent has three primary attacks, in the first he will launch a green fire at you which will leave some fires scattered around the screen, avoid the direct flame and then hit the fires to put them out. In the second attack it will hit the ground, jump at the right moment to take no damage. In the last attack he will try to bite you, dodge him by running away. The technique is to escape until Maleficent launches the green fire, put out one of the fires to bring up the Mickey Mouse Card which if taken will create a stone bridge that will allow you to easily hit the dragon's head, continue like this until Maleficent does not die, then return to the Castle.

Eleventh Floor: Twilight Town

Oblivion Castle

As soon as you get back you will have to deal with Vexen and it will not be easy.

BOSS 14 : Vexen

Victory Award: Mega Ether

Vexen has several attacks, you will understand that he will use Freeze when he opens his hands and shouts, at this point run around without stopping until the danger is not avoided. He might hit you with his shield but the attack is easy to avoid. Last attack is the ice ball that she will throw at you if you stand in front of her (also simple to avoid). You can only hit it from behind and do not use the frost spell because it will give it energy instead of removing it, after beating it you will have an object and a World Card, go upstairs.

Eleventh Floor: Twilight Town

Castelllo di Oblivion

You will see a scene where a mysterious man will give orders to Vexen to eliminate you, soon after you can enter this new and extravagant world (first save that it never hurts).

Twilight Town

This world is totally new and was not found in any version of Kingdom Hearts, Sora remembers other details of Namine. With my solution you will not have to visit all the rooms in the world, it would be the case, however, to gain experience to visit them all and kill all the enemies.
In the first room go left and then continue upwards until you can, when you can't go up anymore go left to enter the special room. As soon as you enter there will be a beautiful dialogue with Vexen that you will have to face immediately afterwards.

BOSS 15 : Vexen

Victory Award: Vexen Card

The attack technique to beat Vexen is the same as before, in fact only attacking him from behind will you be able to damage her. This time, however, his speed has increased and the number of attacks has also increased. In addition to the old ones there is the very dangerous ice daggers which is almost impossible to avoid, the only thing is to try to block his attack with a special card, also watch out for his direct attacks which are very dangerous. Always keep the healing cards ready and remember that to avoid a block you must have high value cards. After winning Alex will make an appearance and the next scene will be terrible, soon afterwards go back to the Castle.

Twelfth Floor: Destiny Islands

Oblivion Castle

Scene full of revelations that I do not want to ruin, as soon as you enter Riku will wait for you that after an intense dialogue something will go wrong and you will have to fight it.

BOSS 16 : Riku

Victory Reward: Mega Potion

The real danger of Riku is always Dark Firaga, devastating if it hits you but it has to hit you and if you are attacked and keep hitting it his dangerous sphere will not do you any damage and will pass over you. The cards must be of a high level and if you need to seek or heal yourself, move away from him and take refuge in one of the corners of the room.
After the battle there will be a big discussion with Donald and Goofy and in the end you will go upstairs alone.

Twelfth Floor: Destiny Islands

Oblivion Castle

New discussion of the brotherhood that seems to have lost some of its security and more and more we understand that Alex is moving the ranks of the game, you will see it with an animated conversation with the Jiminy Cricket and after having removed it you will go to the last world left.

Destiny Islands

Sora returns to his island and finds all the old friends left there a long time ago, this world is similar to the others but has two important peculiarities, the first is that you cannot count with Goofy and Donald and the second is that here the enemies are really strong and eliminating them will not be easy at all. In the first special room you will see it with Riku, but this time it is not the Riku of the Castle, it is the one who created your memory and after the fight you will go in search of Namine.
You will return to the first room, go to the second special room that you will find always going up and then to the right, here you will clash in a Boss very familiar to the players of the first Kingdom Hearts: Darkside.

BOSS 17 : Darkside

Victory Award: Darkside Card

This Boss has three and a half bars of vitality but is not very strong, however the battle will be tiring and it will take you a while to beat him. The strategy to beat him is very simple, get close to his legs and wait for him to hit the ground with his fist, when he does it if you are close to the legs you will not suffer damage and you can immediately hit his hand in order to cause damage, repeat the procedure until you beat him.
After eliminating the Boss Sora will find Namine and after a dialogue he will understand that it is not she who is looking for but Kairi, go to the final room to exit the world and return to the Castle.

Thirteenth Floor: Oblivion Castle

Oblivion Castle

Another dialogue with Naminè, the story is finally understood well and you do not have time to rejoice because the usual Riku will return to challenge you.

Boss 18 : Riku

Victory Award: Riku Card

Here is your worst enemy! (one of the worst), mandatory at least you 0 cards and three very high value healing cards, Riku uses the Combos in two different ways, both devastating, the usual Dark Firaga you know how to avoid and Dark Aurora, this unstoppable attack is very powerful and the only way to avoid it is to use a 0 card as soon as you see that the screen begins to darken (a sign that the attack is about to be unleashed). It will still be very hard and a level above 50 is required to have any chance, move a lot and hit him from the back as soon as you can, reload often and always keep a 0 card in the deck.
After defeating him, you don't have to go near Riku !. Instead, go back to Destiny Islands and save and recover your energy at the save point. Now go back to Riku who will want to kill you but Namine will stop him and will explain that Riku has never actually been there at the Castle and that it is only a magic of Vexen. After the conversation with Naminè there will be another very hard battle.

BOSS 19 : Larxene

Victory Award: Larxene Card

Larxene is faster than Riku but the strategy of staying close to her and attacking her constantly does not change, remember to go to a corner when you have to reload the deck. The witch has several direct attacks but using the 0 cards and always being close to them you shouldn't have big problems, after killing Larxene you will talk again with Namine and eventually you will go upstairs.

Thirteenth Floor: Oblivion Castle

Oblivion Castle

Save the game as usual and then walk through the door to end up in the world of the world.

Oblivion Castle

Sora is constantly wondering who is the person that Naminè made her forget and will finally get back the company of Goofy and Donald, moreover he will know a new powerful attack technique the Trinity Limit (you will do it using a Donald Duck Card, a Goofy Card and a Attack card).
This floor is completely different from the others in fact it will not be a world to face but the castle itself. At first go right until you get to the fourth room, from there go up until you can go left, do it and continue to the fourteenth room, here you will discover Alex's plans and various betrayals in the room. organization, in the end it appears that Alex kills Marluxia.
From here go one room up and then one to the right and then back up again, open the door on the left and you will be in the first special room with a very important Boss.

BOSS 20 : Axel

Victory Award: Axel Card

Here, as always, the 0 value cards and the healing ones are mandatory, you will always have to attack him except he will not try to hit you with one of these two very powerful attacks: Firewall and Firetooth.
With Firewall Alex will make a fire barrier, run to the area opposite to him and you will see that it will take some time for the fire to reach you, take the opportunity to reload the deck or to heal yourself and then avoid it with a jump. The second Firetooth attack will create two fireballs that will attack you at the same time, be careful not to get caught because they hurt, if you are agile you can avoid them but a 0 card would be more appropriate.
At the end of the meeting Alex will say some strange words and you will return to the previous room, from here go one room to the right, one up and then always to the right until you reach a room where you can save (do it is convenient). Now study your deck well and put the most powerful one you have because the clashes will be terrible in a while. Once the tidying up is finished, go out the upper door and go back to the Castle (but weren't you already there?).

Final

Oblivion Castle

Big discussion between Marluxia and Naminè to take away Sora's memory, after the witch's refusal only a fight with Marluxia can make you win the game !.

BOSS 21 : Marluxia

Victory Award: Marluxia Card

Here you will see it with a Boss with very high value cards and whose attacks are exceptionally powerful, also watch out because he will always be on you with his attacks and the risk of a devastating Card Break is always around the corner (you will also have difficulties to cure you).
These are the cards you will need:
Attack cards of level 7 and higher
Level 0 cards
High level healing cards
Maleficent Card (to be enabled as soon as the fight begins)
Neosoldier Card (to be used immediately after Maleficent Card)
The trick here is to never stop and always move non-stop, almost all attacks can be avoided, when he uses the attack of the petals wait for them to cover you to jump and avoid the attack, when he uses the attack of the ax you will have to avoid it in order not to die immediately but you will have immediately after some time to heal yourself or to counterattack it. Cloud attacks are very effective.
After the defeat of the Boss you will discover a terrible truth, Marluxia was not the real one and while Riku will stay with Namine to cure her you will regain control of Sora and you will first go to the left door to save and recover energy and then to the right door to start the last and terrible battle.

BOSS 22: The Real Marluxia and The Robot

Victory Award: -

Here he is finally the final villain, you will not only have to kill him but also that strange robot he is using, first you will have to try to destroy the hands, when you have done so you will notice three roses circling over you, destroy them and then avoid his attack. Now the Boss will turn and you can hit the other arm, do it until it is destroyed.
Once you have destroyed the two arms you can concentrate on Marluxia, it will have two nice full bars and even if it will not be difficult to eliminate it it will cost you a lot of time.
Boss Attacks:

- When he gets up he is ready to jump and hit the ground, when he is about to hit the ground jump to avoid being hit (when he is in the air you will have time to reload).

- When he disappears from the screen he will try to run over you, when he approaches jump to avoid the fight, if you manage to do a Card Break when he uses this attack he will stop in the middle of the room and you can get on the robot and hit the Boss.

- When you see a circle of roses around him he will be about to hit you with a gust of wind, you can try to avoid it but it is really difficult, the only one is to use a Card Break.

- When you have the roses above you in the shape of a sword you will have to destroy them because they are slowing you down, with a Card Break you will destroy them all immediately.

Usually he uses two attacks at a time, as soon as you manage to avoid the second attack him, remember that he will not have very high cards so if you have them you should not have particular problems. As soon as Marluxia is beaten, the Robot will also destroy itself, killing the Boss as well.
Eventually Sora will return to the Castle and seal the door with the Keyblade, Riku will greet you and at the end you will talk to Namine. He will tell you that in order to put things right he will have to make Sora forget the facts of the castle or those of the past. Sora obviously chooses to keep the old memories and promises Namine to look for her in the real world!
