Universal Studios Hollywood is introducing a new daytime experience for its popular Halloween Horror Nights event. The "Unmasking the Horror" tour provides a "behind-the-scenes glimpse" of the attraction with the lights on, offering guests a closer look at the creative details of the haunted houses.

This guided, lights-on walkthrough allows visitors to explore the "Sinners" and "KILLceañera: Music by SLASH" haunted houses. Guests will have opportunities to take photographs in designated areas within these houses. The tour is an add-on and costs an additional $20 on top of the theme park admission for Halloween Horror Nights.

The "KILLceañera: Music By Slash" haunted house, announced as one of the final additions to this year's event, centers on a teenager named Lola who transforms her quinceañera into a "festival of death" as revenge. Guitarist Slash composed an original score for this attraction, including a song titled "15 Candles."

Other new additions for Halloween Horror Nights include the Terror Tram, which will feature new music from the band Ice Nine Kills, putting a dark spin on classic Christmas songs. The character Art the Clown from the "Terrifier" film series will also be present throughout the park outside of the Terror Tram experience. Additionally, "Killer Klowns from Outer Space," based on the 1988 film, and an original house called "Dead, Deader and Deadest," set in an abandoned funeral home, are new attractions.

Previously announced attractions for this year's Halloween Horror Nights include experiences based on "Obsession," "Hackerz," "Fortnitemares," "El Circo de la Muerte," "Blood Bog," "Murder of Crowz," "Shriek of the Banshee," as well as houses inspired by "Stranger Things," "Hellraiser," "Evil Dead Burn," and "Ozzy Osbourne: Prince of Darkness." Halloween Horror Nights runs on select nights from September 3 through November 1.
