Final Fantasy XV is an action role-playing video game being developed and published by Square Enix for the PlayStation 4 and Xbox One. It is the fifteenth main installment in the Final Fantasy series, and forms part of the Fabula Nova Crystallis subseries, which also includes Final Fantasy XIII and Final Fantasy Type-0. Originally a spin-off titled Final Fantasy Versus XIII exclusive to the PlayStation 3, it is a heavy departure from previous games, providing a darker atmosphere that focuses on more realistic human characters than previous entries. The game features an open-world environment and action-based battle system similar to the Kingdom Hearts series and Type-0, incorporating the ability to switch weapons and other elements such as vehicle travel and camping.
