Über Düper Achievement
Collected 600 moves and unlocked the Übertroopers.
See "The Complete Package" for tips.
In order to collect a move, you need to get a flawless rating. When you get a flawless the ring around the dancer’s feet will turn purple and the flash card will turn gold. Do this 600 times across all songs and routines and the achievement will unlock immediately. You will also unlock the Ubertroopers characters which are basically just new skins for the 6 main dancer characters.
