Amplitude

Amplitude is a music rhythm game for the PlayStation 2. The game is the sequel to Frequency, and retains most of the gameplay with some graphical changes and different music. Gutiar Hero and Rock Band, also developed by Harmonix, retain many elements from this game and its predecessor.

The majority of the music is licensed from popular bands in various genres of music, though some is contributed from one of the members of the development team and his band.

Online play is no longer available in the U.S. due to Sony shutting down the servers for the game in early 2007. Multiplayer is still available for 2-4 players on the same PS2.
