Harmonix has successfully matched its $775,000 goal on Kickstarter for Amplitude with 21 hours remaining in the campaign. The Dance Central developer recently admitted that its crowdfunding goal amounted to "less than half of the project budget for the game," the rest of which will come from the studio's wallet. Harmonix held a telethon via Twitch to raise funds for the game, performing songs and playing the original Amplitude for viewers.

The original Amplitude achieved cult-hit status after its 2003 release on PlayStation 2. The game was a follow-up to Harmonix's 2001 music game for PS2, Frequency. Harmonix's goal with the new version of Amplitude is to re-create the frenetic action of the rhythm games, where players guide a ship down a colorful highway and press buttons to match notes in line with the music being played at the time.
