Kingdom Hearts Re:Chain of Memories Walkthrough and Card Battle Basics
Re:Chain of Memories is the prequel you play before Kingdom Hearts II, and its card-based battles are the part most players need to learn first. This guide explains how the battles work and how to move through the story.
In this article
A Kingdom Hearts Re:Chain of Memories walkthrough can carry you through the whole game, and playing it first sets you up for Kingdom Hearts II. Re:Chain of Memories follows Sora's adventure in Castle Oblivion [1]. It works as the prequel step before the main series, so the story makes more sense when you reach the later game.
This article covers how the card battles work, how to get through Castle Oblivion, and what to do once the story ends. Walkthroughs exist for several versions, so check which one you own before you follow one. Match the guide to your copy, and the steps will line up with what you see on screen.
How do the card battles work?
Battles in Re:Chain of Memories are fought with cards, so your job in each fight is to decide which cards to play and in what order. That choice is the main decision you make in every room, more than timing or movement alone.
The StrategyWiki walkthrough groups its card information into separate appendix pages, including Card Points, Sleights, and Powerful Decks [2]. Each one covers a different part of the system, so it helps to skim them before you dive into the floors.
- Card Points are the resource that limits what you can play in a turn.
- Sleights are combinations of cards that work together.
- Powerful Decks are prebuilt setups you can use as a starting point.
Learning how these parts fit together early makes the later rooms much easier. Early floors are a good place to test how cards interact, because a mistake costs you less there than it will later.
A practical way to practice is to pick a small set of attack cards and use them for a few battles. Notice which ones finish enemies quickly and which ones leave you exposed. Once you understand that pattern, you can build a deck around what works for your style instead of guessing each turn.
Pay attention to the enemy you are facing before you commit cards. A fight against a single tough enemy calls for different choices than a room full of weaker ones. Matching your cards to the situation is the skill that carries over to every floor of Castle Oblivion.
When you reach a fight that keeps beating you, go back and look at which cards you used. Swapping one or two cards often changes the outcome more than trying harder. Treat each loss as information about your deck, not as a sign you are doing something wrong.
With the card system under control, the rest of the walkthrough becomes much easier to follow room by room.
How do you get through Castle Oblivion?
Work through Castle Oblivion one floor at a time, and clear every battle on the early floors before you move on. The cards you collect in those early fights are what you will rely on higher up, so skipping ahead usually leaves you underpowered.
Use this routine for each floor:
- Enter the floor and fight every enemy you can reach before you open doors or take stairs. Treat a room as finished only when its enemies are gone.
- After each battle, update your deck with cards that suit the enemies you just faced. Keep the cards that worked and drop the ones that did not.
- When you get stuck, open the walkthrough and find the section for your current room. StrategyWiki hosts a Re:Chain of Memories walkthrough page you can use for this [2]. Destiny Islands splits its complete walkthrough into separate pages, so you can jump straight to the room you need [3].
- Save before every tough fight, especially a boss or a room where you have already lost once. If you lose, you replay only that fight, not the floors you already cleared.
- After a loss, reload your save, adjust your deck, and try the fight again. Small changes to your cards often matter more than a faster button press.
The save habit is the one that protects your time most. A long floor with no save point can cost you a lot of progress if a boss wipes you, so save before you walk into anything you suspect is hard.
If you move through the floors in order, clear each battle, and save before the hard ones, you will reach the later rooms with a stronger deck and fewer restarts.
Which walkthrough should you follow?
Pick the walkthrough that matches the release you are playing. Re:Chain of Memories appears in more than one form, and each form has its own guide options.
If you are playing the PlayStation 2 original
The PlayStation 2 release has its own FAQ-style walkthrough [4]. It is a question-and-answer style guide, so you can jump straight to the spot where you are stuck instead of reading the whole route.
The guide is listed on GameFAQs as a Guide and Walkthrough by falconesque [4]. Because it is written for the original PS2 disc, use it only for that release.
If you are playing the HD 1.5+2.5 ReMIX
The HD 1.5+2.5 ReMIX version includes Re:Chain of Memories [1]. You get it as part of the collection, not as a separate purchase.
For this release, read the walkthrough page on TrueAchievements, which is titled HD 1.5+2.5 ReMIX - - Re: Chain of Memories Overview [1]. It gives you the story setup before you start the route.
If you want the whole route in one place
A wiki walkthrough covers the full route in one place [2]. The StrategyWiki page works as a single document from the first floor to the final battle, so you do not have to hop between pages.
The page also links to appendix pages such as Card Points and Powerful Decks [2]. Open those when you want to build a deck before a tough room, since the card system is where most fights are decided.
Why the versions can differ
The PS2 original and the HD 1.5+2.5 ReMIX are separate releases, so the steps may not match one for one. A guide written for one release can send you to the wrong room in the other.
If you switch between a PS2 guide and a collection guide partway through, slow down and compare the room names before you follow a step. Sticking with one guide from start to finish keeps your progress easy to track.
What happens after the credits roll?
Reverse/Rebirth is a second story mode that opens after you finish the main story. Re:Chain of Memories follows Sora's adventure in Castle Oblivion, and the new mode unlocks once that story ends [1]. Finish Sora's route first, then start the second mode.
When the unlock happens
The unlock comes after the credits roll, not partway through Castle Oblivion. That means you do not need to search for the mode while you are still clearing floors and battles. Your only job until the ending is to keep moving through Sora's story.
Think of it as two steps in a row. First you play Sora's full story from start to finish. Then Reverse/Rebirth becomes available as the follow-up.
A different main character
Reverse/Rebirth follows Riku instead of Sora [1]. You will see the same world from another character's point of view, so the story can feel fresh even in places you already know.
Pay attention to what Riku knows and what he wants. His route gives the second half of the experience its own direction, so it is worth playing for more than the extra time.
The order to follow
- Play Re:Chain of Memories from the beginning and follow Sora through Castle Oblivion until the credits roll.
- After the ending, start Reverse/Rebirth, which is now unlocked.
- Play Riku's story from its opening scene.
Keep this order in mind. If you jump into the second mode before finishing the first, you may miss the unlock and have to come back to it later. Finish the main story, then move on to Riku's route.
Once you reach the end of Riku's story, you will have played both halves of Re:Chain of Memories. That gives you a clear finish to this part of the series before you move on.
Where should you go after Re:Chain of Memories?
Once you finish Re:Chain of Memories, move on to Kingdom Hearts II. The card battles you have practiced are the foundation for the rest of the series, so the next step is to keep going with the main story.
Before you start, read the Kingdom Hearts II walkthrough overview. It covers which version to play and what the import release means for English-speaking players, so you know what you are getting.
If you are unsure what else to play first, check the play order guide. It lays out what to play before Kingdom Hearts II so the story stays easy to follow.
The one thing to remember is simple: finish the story here, then take the next step with Kingdom Hearts II.
