Kingdom Hearts Re:Chain of Memories

Kingdom Hearts: Re:Chain of Memories is set immediately after the events of the first game. It is set in Castle Oblivion, a mysterious castle kept by Lord Marluxia. Sora and his teammates are told that the castle causes visitors to lose their memories upon entering. The lobby and areas between floors are white with flower-themed decorations, but each floor can be transformed into a different world from the first Kingdom Hearts game using "world cards" created from Sora's memories. Like before, many of the worlds of Disney and Square Enix reappear.

Unlike the previous game, the worlds are created from Sora's memories. As such, many of the events experienced in Kingdom Hearts are relived in this game, Sora encounters memory-based versions of Disney characters that he has met before. The individual plotlines differ from those in the original game and revolve around the theme of memory. Just as Kingdom Hearts had several worlds created specifically for that game, Re:Chain of Memories introduces Twilight Town as a world created from memories on "the other side of Sora's heart", in addition to the original worlds of Kingdom Hearts.

Kingdom Hearts Re:Chain of Memories is a full remake of Kingdom Hearts: Chain of Memories, originally released on the Game Boy Advance. It was originally remade for the PS2, and eventually remastered in the collection "Kingdom Hearts HD 1.5 ReMIX". The game was also changed in that completing the "Kingdom Hearts 358/2 Days" cutscenes would unlock additional Enemy Cards that would have been unlocked in the original by having save data from "Kingdom Hearts II: Final Mix"
