The sibling has a Nintendo DS and showed me the game she's been playing.
I am sooooo hooked to it.
The following is just the ad. It doesn't reveal the game's true awesome-ness.
This is just one of the rounds you get to play.
It's bloody DDR for a touch-screen, except with catchier tunes, like 'Sk8er Boi', 'La la Song', 'Material Girl, 'YMCA'. And each round has a storyline, that may be wacky, but by God! The agents will boogie till everything has been solved.
