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. Guitar 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.

In Amplitude, the player controls a ship (referred to as a "Beat Blaster") moving down a path of varying shapes and lengths, containing up to six tracks. Each color-coded track corresponds to a different aspect of the song, such as percussion, synth, bass, or vocals, and contains a sequence of notes. As the player hits buttons corresponding to the note placement on the track, the notes activate a small portion of the track. If the player successfully activates enough notes in sequence, the track is "captured" and the section will play automatically for a number of bars, freeing the player to capture another section.

The object of the game is to capture a sufficient amount of sections to reach the end of the song. If the player continually misses notes, an energy meter empties until the game is over.
