The Binding of Isaac: Unholy Edition is a DRM-free PC and Mac version that includes a free Steam gift key, the full soundtrack, a poster and a 40-page art book. Developed by Edmund McMillen of Super Meat Boy's Team Meat, The Binding of Isaac premiered on Steam in September along with an adorable plush from the Team Meat Shop on Etsy.

If you don't yet know why that darling doll is crying, go ahead and pick up The Binding of Isaac on Steam for $5, or wait for the Unholy Edition to launch at an unknown price. Or you can just listen to this song, whose recurring line is "To the basement, people, to the basement / Many surprises await you / In the basement, people, in the basement / You hid there last time, you know we're gonna find you."
