Dance Dance Revolution A20

All NONSTOP courses can be switched to CHALLENGE MODE if the LIFE GAUGE option is set to RISKY or LIFE4.

Class, intended to measure the player's skill, places a stricter rules on the gameplay; the player cannot change Turn and Assist options and is forced to play on the "Grade" life gauge, which starts out full and depletes faster if it goes down.

With the installation of the blue interface, it's possible to switch languages in-game, including Japanese, English and Korean as options.

For players in Asia territories and North America, this requires "Premium Play" to be selected when the game starts.

For players in Japan, Premium Play requires Konami's PASELI payment system.

EXPERT charts require two stage clears or equivalent progress from failed attempts.

Part 2 started on July 7, 2020, and ended on September 7, 2020, and all songs are unlockables via EXTRA SAVIOR PLUS since March 8, 2021.
