While there are dozens of haunted attractions throughout the USA, one Halloween-related event trumps them all: Universal Studios’ Halloween Horror Nights in both Orlando and Hollywood. iHorror was privileged enough to be invited to a recent media preview night for the huge 25th annual Orlando event, and we’ve got the full low-down on what is likely to be HHN’s best line-up to date. Below you’ll find the skinny on all haunted mazes, shows, and scare zones, as well as photos designed to give the curious an early look at what’s in store.

Leading the pack of nine haunted mazes this year is Freddy vs. Jason, arguably the biggest name to grace this year’s event. According to HHN head honcho Mike Aiello, the maze will begin in Camp Crystal Lake and showcase some of Jason’s greatest kills, before heading over to Elm Street and taking guests inside some of Freddy’s most iconic moments. Then, the maze ends with the big showdown between the two icons, ending in a result some may not expect. Wanna know who wins? You’re gonna have to go to HHN and find out.

Next on the maze docket is the return of the fan-favorite maze based on an An American Werewolf in London, which is consistently cited by HHN devotees as one of the greatest ever. This year’s maze will be an almost exact recreation of that triumph, although HHN designer Charles Gray assured us that there would be even more werewolf madness for visitors to enjoy/run from.

One of the coolest mazes by far is 25 Years of Monsters and Mayhem, presented by returning Halloween Horror Nights icon Jack the Clown. As you might imagine, this attraction features characters from some of the best past mazes and scare zones ever to grace HHN’s hallowed history.

Expanding on that theme, the mazes RUN: Blood Sweat and Fears and Body Collectors: Recollections capitalize on HHN’s deep past bench by each combining ideas from two previous mazes to create one new frightening bouquet of terror. RUN combines a Running Man-style deadly game show with the population of the deadly Hellgate prison, while Body Collectors combines the titular ghouls with the residents of the Shadybrook asylum that terrorized guests as part of the Psychoscareapy series of attractions.

Also gracing HHN 25 are mazes based on popular Blumhouse Productions horror series The Purge and Insidious. Both feature iconic moments from all films in their respective franchise, with the former placing guests right in the middle of the annual event where all crime is legal. We press folk got the opportunity to tour the Insidious maze before we left for the night, and wow was it amazing. Even the most hardened HHN vets are unlikely to see some of the craziest scare moments coming. One word: shotgun.

Rounding out the list of haunted mazes are The Walking Dead: The Living and the Dead and Asylum in Wonderland 3-D. The Walking Dead maze takes guests on a journey through season five, including stops in Terminus, the basement of a flooded store that will feature underwater walkers, and the infamous revolving door where poor Bob met his doom. Asylum in Wonderland is an Alice-focused expansion of HHN’s beloved Scary Tales series of mazes, and seeks to answer the question of whether the young woman is really going on adventures in Wonderland or is just really freakin’ nuts.

Of course, monsters and mayhem aren’t only confined to the haunted mazes, as HHN 25 has created five all new scare zones full of horrific scenes ready to scare the pants off attendees. These include a section featuring the aforementioned escaped residents of the Shadybrook Asylum, a section reuniting all of HHN’s famed icons, a section putting a steampunk spin on classic fairy tales, a section focusing on the primal evils that serve as the roots of Halloween itself, and the All-Night Die-In, which alternately features appearances by classic Universal Monsters and modern boogeymen like Chucky and Freddy.

Finally, HHN guests can take in the 2015 installment of staple comedy show Bill and Ted’s Excellent Halloween Adventure, and brave The Carnage Returns, a new show hosted by Jack the Clown himself. If all that wasn’t enough, most of Universal Studios’ normal rides will be open too.

Halloween Horror Nights 25 begins Friday, September 18th and runs on select nights until November 1st. If you’ve never attended, you really need to. There’s nothing else that celebrates the horror genre quite like HHN, and there’s nothing like the breathless feeling you get when placed inside some of your favorite films of all time.
