The game is a downloadable title and was released on October 20, 2010 on the
PlayStation Network and
Xbox Live Arcade services. A port to
Microsoft Windows through the
Steam platform was released about a year later. It was later released on
Linux and
OS X as part of the Double Fine
Humble Bundle. The original
Costume Quest prototype was released for
Microsoft Windows as part of the
Amnesia Fortnight 2012 bundle on November 19, 2012.
Expansions An additional downloadable chapter, "Grubbins on Ice", was made available on December 21, 2010, alongside a free patch to correct some of the game's performance and gameplay problems. Taking place some time after the events of the main game while winter falls upon the kids, they find a portal to the monster's world, Repugia, where Lucy is captured by the monsters during a revolution. The other three kids don their costumes to help save Lucy. While many of the core game's features carry over into the add-on, new costumes and abilities are available in the expansion.
Windows version Costume Quest was originally released as an Xbox 360 and PlayStation 3 downloadable game. According to Schafer, while they would have liked to create a version for Microsoft Windows, they as the developer did not have the final say on which platforms would be supported. Schafer commented that THQ did not see a financial benefit for creating the Windows version at the time. However, a year after
Costume Quests initial release, a version of the game for Windows was released through the
Steam platform. This version was funded by Steven Dengler's Dracogen Strategic Investments, who had also previously funded a
OS X port of Double Fine's
Psychonauts a few weeks before this new release. The Windows release includes the "Grubbins on Ice" content. Though the full terms of the deal was not announced, Dengler stated that he didn't expect to make a large profit on the investment but to at least repay the investment "and then some".
Sequel Costume Quest 2 was announced in March 2014, and was released on October 7 of that year. It was released for Linux, OS X, PlayStation 3,
PlayStation 4,
Wii U, Windows, Xbox 360, and
Xbox One in October 2014. Wren and Reynold return in the sequel, which introduces more costumes and features a "deeper and juicier" battle system according to Schafer. The game's plot involves Wren and Reynold traveling into both the past and the future in order to undo the actions of the evil time-traveling dentist Dr. Orel White, DDS.
Other media Double Fine has teamed with
Oni Press to produce a one-off comic book,
Costume Quest: Invasion of the Candy Snatchers, written and drawn by Zac Gorman, to be released around the same time as the game sequel's release. Gorman had previously drawn a
Costume Quest comic for his
Magical Game Time webcomic series, which got the attention of Double Fine and led to this collaboration.
Frederator Studios had announced in May 2015 that it was producing an animated short based on
Costume Quest. The short had been planned to be written and storyboarded by Zac Gorman and directed by
Pat McHale. In February 2017, Frederator Studios announced the project has now become an animated series to be distributed as
original programming for Amazon. For the series, Bryan Caselli and
Will McRobb serve as the showrunners with
Fred Seibert, Kevin Kolde and Eric Homan serving as executive producers. Having worked on the original short, Zac Gorman was initially approached as showrunner, but turned it down, though his style became crucial to the show's look, and he contributed as a writer on 2 episodes.
Costume Quest is Frederator's first project with Amazon. The first half of season 1 was released on March 8, 2019. The second half of season 1 was released on October 11, 2019. A holiday special
Heroes on Holiday was released on November 21, 2019. ==Reception==
