Both a new Humble Bundle and a new Indie Game Music Bundle have come out this week (coincidentally, as they’re otherwise unrelated).
The Humble Bundle includes Bastion, Amnesia: The Dark Descent, Psychonauts, LIMBO, and Superbrothers: Sword & Sworcery EP.
The Indie Game Music Bundle includes the OST’s of Terraria, Plants Versus Zombies, Dustforce, Ilomilo, and Frozen Synapse (plus much more if you pay over $10).
