Universal Studios Hollywood has unveiled the final additions to its fan-favorite Halloween Horror Nights event.

Among them are the return of a haunted house based on the 1988 camp slasher classic Killer Klowns From Outer Space. Other new frights include “KILLceañera: Music by SLASH” and “Dead, Deader, Deadest.” There will also be a fiery stunt show based on The Purge franchise. Additionally, the park’s Halloweenified Terror Tram returns with an all-new host, Art the Clown from the Terrifier movies.

Halloween Horror Nights starts on Thursday, September 3 and continues select nights through Sunday, November 1.

Previously-announced haunted houses include those based on Sinners, Stranger Things, Hellraiser and Evil Dead as well as one that pays homage to Ozzy Osbourne, the Prince of Darkness.

Additionally this year, Universal Studios Hollywood will debut “Unmasking the Horror Tour Add-On,” a behind the scenes, daytime experience for guests who want a closer look at the craftmanship that goes into Halloween Horror Nights.

Ticket options for the main event include General Admission, Universal Express Ticket, R.I.P. Tour, Day/Night Ticket and After 2 p.m. Day/Night Ticket. Plus, Early Access Ticket provides entry to select haunted houses beginning at 5:30 p.m. (subject to change). Also, the popular Frequent Fear Pass and Ultimate Fear Pass allow guests to experience scares again and again throughout the season.
