-Project DIVA- X is the eighth main installment in the Project DIVA series. The game was released March 24, 2016 in Japan, for the PS Vita. The PS4 version, a first for the series, was released on August 25, 2016. The game was released in North America for the Vita and PS4 on August 30, 2016. The game's theme song ("Tsumi no Namae") is composed by ryo.
A new "Live Quest/Cloud Request" is a new feature in which quests are listed on the bulletin board in Diva Room/Home. The quests vary depending on the areas/clouds, which are five in total (Neutral, Cool, Cute, Beauty and Chaos). By "filling" up the power of song, the quest is progressed and eventually passed when a right amount of "Voltage" is met.
In Live Quest/Cloud Request Mode, there are five types of areas/clouds that exist: “Neutral,” “Cute,” “Cool,” “Beauty,” and “Chaos.” The rhythm game’s songs are stationed throughout each area. Each module and accessory equipped has a set element. If the player coordinates a module and accessories with the element of the rhythm game, the initial value of the Voltage Rate will increase and they can earn Voltage more efficiently. 2.1 The North American release will re-title some of the attributes: “Classic,” “Cute,” “Cool,” “Elegant,” and “Quirky.”
In addition to obtaining modules by purchasing them with Live Points, a new module acquisition feature has been added. The "Module Drop" feature will be reward a random module by the completion of a quest/request, if the quest/request conditions and “Chance Time” are both cleared. In it an event will trigger conversations among the characters in the quest/request.
The new "Rush Notes" feature sets up an alternative for players to gain higher scores. This can be done by pressing the corresponding buttons repeatedly when the word "RUSH" appears on the screen.
In accordance to theme of the game "Live & Produce", players can now produce their own "live" and change the stage of the song, along with the modules and accessories, as seen in previous games. Consequently, -Project DIVA- X isn't expected to have any "Story PVs", and the new PVs are all supposed to be in a "live" style.
For each module there are set “skills” that influence the rhythm game. Example skills include “Recover,” which cover up mistakes made during the rhythm game, “Rate Up,” which lets players earn more Voltage, skills that influence module drop rate, and more.
The 'HD' in the Japanese PS4 title apparently stands for "Honki DIVA".
Also, while the PS Vita version runs at 30fps, the PS4 version runs at 60fps.
When the PSVR came out alongside with the worldwide release of Hatsune Miku VR Future Live with Project Diva, the game receives a patch to add the VR Viewer Mode in Live Edit/Concert Editor Mode.
Also, another patch is released when the PS4 Pro came out. Not only it improves the reflection quality and the ability to play the game and take snapshots in 4K, but the VR Viewer Mode in Live Edit/Concert Editor Mode runs at 90fps. This also applies to Hatsune Miku VR Future Live with Project Diva.
Some songs in Live Edit/Concert Editor Mode have full versions of those songs.
