Harmonix and MTV Games have both released a new music-based game for the iPod. The rhythm game, entitled Phase, is now available on the iTunes store to purchase and download for play on an iPod Nano with video, iPod classic, or fifth generation iPod for the price of $4.99.

Harmonix's and MTV Games' Phase utilizes the iPod's click wheel to provide arcade-style rhythm gaming using the player's own music collection stored on his or her iPod. Phase players may choose between  the Quickspin or Marathon gameplay modes. The difference between the two Phase modes is that Quickspin involves one song at a time, while Marathon engages Phase players in a five-song series wherein every succeeding song is more difficult than the previous one.

What probably stands out the most, however, is neither the Phase concept itself, nor the game's animated backdrops (created by Artist Aaron Stewart), but the experience that both Harmonix and MTV games want the iPod owners to have. As Kasson Crooker, Harmonix Lead Producer for Phase put it:

We wanted to create something that took users beyond the standard game format, tap into the unique design of the iPod, and give players a fresh, new way to deepen their relationship with their own music--the music they love.
