Amplitude (PS2)

Amplitude is a music video game developed by Harmonix for the PlayStation 2. It is the sequel to Frequency. The game was released on March 25 2003 In Amplitude the player controls a beat blaster ship across a lane of six tracks, each track representing a musical instrument and containing note gems that the player shoots at in time with the music. The player earns points for accurate playing and increases their scoring multiplier by playing a series of flawless sequences; the player loses energy by missing too many notes and can end the song prematurely if they run out of energy. Compared to the original Frequency which used more electronica and trance music, Amplitude included additional pop rock songs in its soundtrack.
