Discombobulator

You are the greatest inventor / musician of your time; you have created the... Discombobulator. But you are too good of an inventor, and accidentally made your crude music machine a sentient weapon of mass destruction that will level your continent if it's artistic expressions - melodies - aren't kept in check.

Battle against your own creation in the "campaign" , or hop into sandbox mode to lay some sick grooves.
