Three encore levels are unlocked in each chapter after you complete the finale, for a total of twenty-four levels. Recommend not starting these until completing the story on normal, since these levels are some of the most challenging in the game and will require some more advanced moves to overcome. Like the Finales, these levels are all on a timer and if it runs out it's game over. The time limit on some of these is quite strict, so some practice and memorization will be necessary to succeed. Additionally activating a checkpoint will add ten seconds to the clock. Easiest to do on solo normal.
