Guardians of the Galaxy — Mission: BREAKOUT! at Disney California Adventure Park is getting a special Halloween overlay, transforming nightly into Guardians of the Galaxy — Monsters After Dark during Halloween Time, Sept. 7-Oct. 31, 2018.

The Monsters After Dark transformation features Rocket, who has to distract all the monsters he has unleashed inside the Fortress, as he attempts to rescues his little friend, Groot.

The transformation from Mission: BREAKOUT! to Monsters After Dark happens each evening. The Collector’s Fortress goes dark, alarms sound and special lighting on the exterior of the Fortress alerts guests that something inside has gone awry.

As guests enter the Lobby of the Fortress, there are flashing alarms and creepy sounds warning that creatures have escaped their vitrine cages.

In keeping with the dark humor of the experience, an all-new 1970s-style punk rock song, “Monsters After Dark,” was written especially for this attraction by the composer for the “Guardians of the Galaxy” films.

Joe Rohde, creative executive for Walt Disney Imagineering, called this Halloween version “creepy, chaotic and very funny.” Rohde worked on development of the original attraction.

Guardians of the Galaxy — Monsters After Dark is only available during Halloween Time, which runs until Oct. 31. Check park time guides or disneyland.com for the timing of this nightly transformation.
