Jourdal has uploaded video of the challenges for 7 out of the games 13 playable characters. These videos showcase Yu, Naoto, Labrys, Aigis, Chie, Elizabeth, and Mitsuru’s challenges set to their respective character music. Jourdal says that this time Arcsys chose to have Challenge mode have 30 combos this time, 1-10 are moves, 11-20 are basics, and 21-30 are advanced combos. 30 is something specific rather than just a really long combo like BlazeBlue.
