The game sounds like an action-RPG remake of the Japan-only mobile game Kingdom Hearts: Coded, in which a virtual Sora retraces his steps through the original Kingdom Hearts. "Jiminy Cricket is looking over the journal he used to document his first adventure with Sora when he discovers a mysterious message," according to the description of Re:Coded included in Square's E3 press release. "He didn't write it – so how on earth did it get there? King Mickey is determined to find out, so he and his friends decide to digitize the journal and delve into its deepest secrets. Inside this "datascape" dwells a second Sora who is about to embark on a grand adventure of his very own."
The game currently has a "TBD" release date. Square Enix didn't specify how much of the game would be shown, but considering it's just been announced, we expect little more than a trailer.
