Beatmania IIDX 16: Empress

Beatmania IIDX 16: Empress is the 16th game in the Beatmania IIDX series of music video games. It was released in arcades by Konami on November 19, 2008 (11 months after the arcade release of Beatmania IIDX 15: DJ Troopers). The game features over 50 new songs, some of which are unlocked over Konami's e-Amusement platform. The design of Empress's interface is based on a pink color scheme, dominated by sparkles, butterfly wings, and motifs of royalty and jewellery. A PlayStation 2 port for the game was released on October 15, 2009, simultaneously in Japan and South Korea.

Gameplay
Core gameplay remains the same on Empress. A new hidden modifier called "ALL-SCRATCH" changes most of the notes to scratches. More tutorials have been added to the Tutorial mode from DJ Troopers. Many sound effects in the user interface have also been changed. A new mode that is introduced before DJ Troopers CS, "Hazard Mode", instantly fails the player if a combo is broken many times (effectively requiring a full combo in order to pass the stage). To access this mode, All the black buttons must be pushed (When highlighting Free mode in mode selection) to activate the Hazard mode.

The upgrade to Empress also comes with a new turntable design, which has been built to be easier to trigger, and also features a more textured surface.

e-Amusement
More advanced statistics can be accessed through e-Amusement's online components. Jewels can be collected for the Empress Place system using e-Amusement.

Empress Place
Empress Place is the extra stage system used by Empress. During regular play, players randomly accumulate colored jewels (the algorithm has not been disclosed). These jewels are used to unlock the 3 songs located in the its first set of stages, each stage representing a famous empress. The 3 currently known stages are Kung-fu Empire by 飛燕流舞 (Consort Yang Yuhuan), Arabian Rave Night by dj MAX STEROID (Cleopatra), and Marie Antoinette by Marguerite du Pre'.

New songs
*1 NΦ CRIME had 2 versions in Empress.

*2 was originally only playable in Beginner mode. A patch over e-Amusement unlocked it for regular play.
