Harmonix, the original developer of Guitar Hero and most recently known for its upcoming Rock Band, snuck out a tasty little treat for iPod owners this week. Available exclusively from the iTunes Music Store, phase is essentially a miniature Guitar Hero.
Phase: What is it?
Phase is an interactive music game that challenges you to tap out the beat of a song. The premise is simple and very similar to the "scrolling circles" gameplay made popular by Guitar Hero. As tracks on the iPod play, circles and sweeps / phrases--swirl-y lines to follow with the iPod's touch wheel--scroll toward you. Hit them correctly with the wheel and center button and you'll earn increase your streak and earn more points.
This looks familiar, doesn't it?
Unlike Guitar Hero, each song is divided by checkpoints that function as phrases. You're judged on the fly by the familiar "star" rating--more stars means a better performance--at each checkpoint. Each phrase in a song has a specific star requirement that you'll need to reach to complete that phrase. Mess up and you lose one of four "life" hearts--lose all your hearts and its game over.
