Crossplay

Is Kingdom Hearts Re:Chain of Memories crossplay?

Crossplay does not apply to Kingdom Hearts Re:Chain of Memories: it has no online multiplayer.

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"
