The digital soundtrack albums for Costume Quest and Costume Quest 2 by Psychonauts series composer Peter McConnell are hosted on developer Double Fine's Bandcamp page.

Costume Quest launched in October of 2010 for PlayStation 3 and Xbox 360, along with Windows, Mac and Linux. The game takes place on Halloween and tasks a party of trick-or-treaters with exploring the local neighborhood collecting candy and costume items. The eight-track soundtrack is also streaming on Spotify and Amazon Music Unlimited.

Costume Quest 2 followed in October of 2014 for the gaming platforms, in addition to PlayStation 4 and Xbox One. This time, the party travels through time to thwart a villainous dentist's plan to eliminate Halloween from human history.
