The Kickstarter campaign for Amplitude has been funded, with Harmonix attracting the required funding with very little time to spare. With just hours to go, the rhythm action game has now cleared $800k (they asked for $775k), although it's looking decidedly unlikely that the game will get anywhere near it's first stretch goal (online head-to-head multiplayer). The game, which is now heading to PS3 and PS4, is inspired by the 2003 PS2 title of the same name.
