How do you get ninja and icon crew on dance central 2?

[Victor Cavazos]

I noticed today that I have a new crew on my dance central 2 game called the Icon crew? My sister plays when i'm not home and she's not old enough to understand if she did something, so I have no idea how it happened? I read on wikipedia that a ninja crew is also available? How do you unlock these things? And on a seperate note, are there more original costume unlocks besides Angel and Aubrey??

Icon Crew & Ninja Crew can be unlocked by the Harmonix Company.
With this being said Crews need to be unlocked by what the community is doing.
Like for example: On Dance Central 2's Main menu you'll see on the left side "Community Stars"
Harmonix wants people to shoot for that milestone To pass 100 Million Stars.
Now that we have passed it they have gave us a free crew "Icon Crew" W// Marcos & Frenchy.

The Next Milestone is to hit 10,000 Sign ups for Dance Central 2 Challenge App On Facebook.
That will unlock us The Most wanted crew "Ninja Crew" With Pink Ninja (Male) & Blue Ninja (Female)

There are other Milestones but, Those are for original costumes for Taye & Emilia From Dance Central 1.
