Back in 2008, Dylan Fitterer released Audiosurf, a game where you race through block-filled levels generated from your own music library. Since then, there have been ramblings of a follow-up called Audiosurf Air. Well, Audiosurf Air has been renamed to Audiosurf 2, and it's hitting Steam Early Access today, according to the developer's own Twitter.
I'm 99% certain I'm the only one here whose heard of Audiosurf, which is a DARN shame.
Game was stupidly addicting and the sequel looks great.
