Amplitude was a pretty groundbreaking PlayStation 2 release back in 2003 and very much served as the precursor to Guitar Hero, Rock Band and whatnot. It was also an awesome game with a great soundtrack, so they are interested in seeing how fans react to this Kickstarter campaign.
They are looking for at least $775K to get this project going, and with 2,400 backers and $7,100+ pledges so far, they may be on their way.
Check out the video preview and concept art they'be put together for the project, below.
