The game was originally announced back in June during the 25th Anniversary celebrations of the original Final Fantasy VII. During an interview in July, producer Yoshinori Kitase stated that fans should consider Crisis Core: Final Fantasy VII Reunion a part of the larger FFVII Remake efforts, hinting that it might not be a 1 to 1 remake or remaster of the PSP entry. Possibly good news for those of us who got emotional at the ending of the original.
Crisis Core: Final Fantasy VII follows Zack Fair, a young SOLDIER operative who works for the Shinra Electric Power Company. Zack dreams of making it to 1st class under the tutelage of his mentor Angeal, and his hero, Sephiroth. It acts as a prequel to Final Fantasy VII offering more details about the FF7 world as a whole, and the characters and objects that populate it. Such as a certain flower girl, mako energy, and the famous Buster Sword.
Pre-orders for standard and ‘Hero’s Legacy’ steelbook copies of the game are live now on most retailers. However, Japan wins again with a deluxe edition exclusive box. Styled after the confiscated letters you-know-who sends to Zack, this edition includes an artbook, a Zack Fair kai-arts figure and a mini soundtrack.
