Rock out to your favorite music in this music and rhythm game from the creators of Guitar Hero and Rock Band. Phase is played in a forced single-point perspective view of a three line track. Down each line come colored circles, and the player must click the corresponding button on the click wheel when the circle reaches the bottom of the screen. The circles are arranged on the track in relation to the beat of the music track being played. Additionally, there are occasional series of smaller, more closely spaced dots that will sweep across the track. These require the player to swipe their finger across the click wheel at the correct pace, instead of clicking the wheel buttons. The game comes with Easy, Medium, and Hard settings available for immediate play. After completing a marathon with the Hard difficulty setting, Expert mode is made available. In the same way, completing a marathon on Expert unlocks Insane mode. The difficulty settings control the speed of the track and the number of the dots, as well as their value.
