The lyrics were written by director Soichiro Morizumi, and the themes were composed by Yuzo Koshiro. The game's opening and ending themes, 'Sekai wa Hitotsu no Butai' (All the World's Stage), and 'Tsuki Akari no Curtain Call' (Moonlight Curtain Call) were both performed by marina. Unlike the previous game, the western versions features no altered content from the Japanese version and are in multiple languages. The game was originally going to have a simultaneous worldwide release, but the North American and European releases were later delayed to early 2016. It was confirmed in an interview that the game will address the criticisms of the original (such as the story) and that there will be some 'surprise' announcements.

The game was officially revealed to the public three days later. Before its expiration, Project X Zone 2 was announced early to attendees of Bandai Namco's 'Level Up' press event in Milan, Italy on April 10, which was prematurely posted on Italian news website E-duesse before being retracted. On April 8, 2015, launched a teaser website with a countdown that would expire in five days, revealing a secret project from Bandai Namco Entertainment.
