Icon Crew is a new crew for DC2. They are represented Frenchy (left) and Marcos (right). Their names are taken from the games choreographers Marcos Aguirre and Frenchy Hernandez. In appearance, they are almost exactly like the icons on the flashcards, hence the name.
They can only be unlocked if you have an xbox live account gold *prepaid* or silver *free* since the game will update its self once online. You don't need a facebook page to do the challenge either. That was just for Harmonix to release the crew officially.
HINT: Starting your first xbox live account you get the first month free. Frenchy's Birthday: April 13th
Marcos' Birthday: April 18th
