Universal Studios is rolling out its houses of horror across the country—opening three major hubs that monster fans can make their Halloween season travel destinations—in this month’s theme park news.

io9 was invited by Universal to experience the very big bag of tricks and treats the theme park creatives are unleashing into the world for fandom fiends seeking thrilling frights. On the West Coast, Universal Studios Hollywood prepares to open the vault with the Fallout house inspired by the Prime Video series and Bethesda video game franchise, alongside its other horror property offerings, come September.

Meanwhile in Las Vegas, AREA15 has opened the gates of Universal Horror Unleashed, a desert warehouse that holds haunted gateways to chilling cinematic experiences. And of course things are already getting started at Halloween Horror Nights Orlando with Terrifier’s Art the Clown being set loose alongside the Five Nights at Freddy’s gang.

Universal Studios Hollywood Fallout lights on tour

HHN Hollywood creative director John Murdy walked through the Fallout house with press to explain the story guests would be experiencing nightly during the Halloween event’s run. “Going through the series, my initial reaction was, ‘Wow, this is a huge world,’ and there’s three different kinds of storylines going on with the show. There’s Lucy’s storyline where she’s searching for her father, there’s Maximus’ storyline with the Brotherhood of Steel, and then there’s the Ghoul and his storyline—kind of going from being a TV actor cowboy to his transformation into this bounty hunter character.”

“So what we decided ultimately to do is we would pretty much be following in Lucy’s footsteps,” he shared, as we saw the under-construction vault setting for the wedding leading to her eventual breakout through the vault door.

“So we’re gonna be taking you from the vault to the wasteland, meeting all the characters along the way,” Murdy continued, and elaborated that Hollywood’s version of the house will offer different set pieces than Orlando. One major difference is that the West Coast will get the mutated Yao Guai bear, whereas Florida will get the Gulper.

Murdy knew one thing for certain: “And then for us, when I saw the Super Duper Mart sequence, which is actually the fourth episode of Fallout, I was like, that is tailor-made for a finale to a Halloween horror house because it’s when all the ghouls are breaking out.”

Murdy acknowledged that the Fallout house would also include many Easter eggs for the show and the games, such as a final scare piece to hype up season two of the Prime Video series.

Murdy also discussed the making of the other major horror video game and now movie franchise Five Nights at Freddy’s with press on a more extensive and detailed BTS tour showcasing the Jim Henson’s Creature Shop puppets, which can be found here.

Universal Horror Unleashed at AREA15 Las Vegas

In Las Vegas, Universal’s year-round horror haven is now officially open with houses that feature The Texas Chainsaw Massacre, the Universal Monsters, The Exorcist: Believer, and HHN West’s fan-favorite Scarecrow. The Sin City attraction, which io9 attended as a media guest, is the gem of AREA15 Zone 2; it aims to attract immersive-experience fans to a new side of the Strip that elevates experiential entertainment and dining.

Universal Horror Unleashed features spooky sips and eats in addition to live acts, including HHN East’s icons Jack the Clown and Chance—who perfectly suit the chaotic clownery of Vegas.

Many HHN fans will notice that neither Orlando nor Hollywood features a Universal Monsters house this year and that’s because of Universal Horror Unleashed. And when we say it’s the best one yet, we mean it mostly because it finally debuts the Creature From the Black Lagoon as part of the action.

There’s a whole under-the-sea sequence where you wade past seaweed to come face-to-face with the creature that is swimmingly well executed. On top of that you’ll encounter Frankenstein’s Monster, the Bride, the Phantom of the Opera, Quasimodo, the Wolf Man, and the Mummy—along with the Gill-man—in an all-out mash that you’ll want to go through over and over again.

Universal Studios Orlando HHN and Epic Universe

While we haven’t yet visited HHN Orlando, the fun officially kicks off this weekend with the annual event’s opening. To celebrate, Art the Clown from Terrifier has taken over the social media account to show he’s taken Jack’s place as the resident clown at Universal Studios in Florida.

And of course, if you’re hoping to see the Universal Monsters while you travel to the East Coast, you can make a day of it at Epic Universe with a visit to Darkmoor and Frankenstein Manor for Monsters Unchained—and then of course go scream your face off at HHN. There’s also no telling what monsters you’ll run into; there could be an Invisible Man or a wild Ygor looking for the Frankenstein creations.
