With support of enough fans, Harmonix reached its goal via Kickstarter to get sufficient funds in its last day to bring a revival of the Amplitude to the PlayStation 3 and PlayStation 4.
The rhythm-action game Amplitude, along with Frequency, brought new meaning to interactive music during the PlayStation 2 generation.
Now that the first and most important goal of $775,000 has been reached, Harmonix could get more support to add online head-to-head multiplayer support.
