General Information

Changes

Scraps the original typeface of the beatmania IIDX logo used in AC EMPRESS
First IIDX with "charge notes", where you hold down the key for a certain period of time and release it at the end of the note.
First IIDX game with Backspin Scratch, where the player must continually spin the turntable in one direction and, at the end of the note, spin the turntable quickly in the opposite direction.
Dark theme with shades of blue and black, similar to AC 10th style.
Ghost now displays FAST or SLOW along with the EX Score difference.
The option window has changed significantly, showing in the center with one player and showing a list of all options for a key when changing the option for that key.
Has an electric BGM sound
First IIDX game with Party Mode

PARTY MODE Features:

only available for singles play.
For each "event", you are given a specific songlist with the goal of gathering fans.
3 songs per play.
You can use options in this mode.
The number of fans you gathered is related to your EX score.
There are separate events, with events being unlocked as you gather more fans. As of now, there are six events, with five being locked from the beginning.
Seems to be a mode aimed for beginners, as nearly all the songs on the first three events are on BEGINNER difficulty.

This is based on the location test only and may be subject to change.
