Unlike Final Fantasy XIII, there is scarcely any information surrounding the gameplay and battle system of Final Fantasy Versus XIII because no formal footage has been shown by Square Enix of the gameplay online or within video game magazines.
Within recent Japanese gaming magazine interviews, Tetsuya Nomura has stated that Versus XIII's gameplay will be a realistic derivation of Kingdom Hearts's battle system with some elements of a third-person shooter aspect. Nomura has also stated that the game will depart from the light and magical aesthetic of his previous directorial games (i.e. Kingdom Hearts) and opt for a darker, bleaker world that is intended to counter previous Final Fantasy installments. In formulating a realistic world, Nomura has stated that he wants the characters to be "believable" and thus realistic. As a testament towards his desire for realism; in the PlayStation Premier trailer, in contrast to previous Final Fantasy titles, Versus XIII had a greater display of graphic violence with an instance of blood.

Nomura has also stated in Dengeki PlayStation that he aims to create previously unseen "tricky" battle sequences, reminiscent of the CGI film, Final Fantasy VII Advent Children.[4]
