Named as one of the Top 10 haunted houses in the nation by USA TODAY and recognized as one of the best haunted attractions in the world by Travel Channel, Fright Dome is celebrating its 15th Anniversary on the Las Vegas Strip. Beginning Friday, Sept. 29, Fright Dome will take over all five acres of The Adventuredome theme park at Circus Circus Las Vegas transforming, it into an immersive and terrifying attraction featuring six haunted houses, multiple scare zones, thrill rides in the dark and more!

New for this season, Jason Egan, owner and creator of Fright Dome is treating fans to the largest haunted house in the event’s tenure, appropriately named Zombie City. For the inaugural launch of the acclaimed haunted attraction in 2003, Egan and his team began implementing zombies into scare zones and haunted houses. To celebrate the 10th anniversary of the event in 2012, Egan teamed up with the late godfather of horror George A. Romero to infuse a new level of zombie-themed scares. Now just a mere five years later, Egan and his team will honor the teachings of their idol with more than 15,000 square feet of zombie metropolis. Guests will be hunted as they make their way through the virus-filled city of the dead.

Known for its dark-twist on Christmas and all things Krampus-lore in years past, the 2017 season also will see Fright Dome take on a variety of festive holidays in its innovative new Happy Hell-idays house. Something wicked lurks within as Egan and his team of experts bring to life the most dreadful of celebrations, including Valentine’s Day, St Patrick’s Day and more. From the blood-stained teeth of the Easter bunny to a Thanksgiving feast where guests may become the main course, this creative addition to the Fright Dome lineup is guaranteed to test even the bravest of festive souls.

Equally as exciting, and available exclusively to guests upgrading to Fast Pass or a VIP tour this season, is the new isolation-style haunted house Lights Out. Upon entering the attraction, guests will immediately be divided from their group and be handed an old flashlight to aid them as they wander through the darkness alone. Separated from everything and everyone, guests will have to rely on their flashlight to illuminate the dreadful inhabitants lurking around every corner.

What’s more, making their return to commemorate 15 years of terrifying mazes are fan-favorite houses Chainsaw Massacre and Killer Clowns in 4D. Lastly, another original creation from Egan’s all-star team, HEX, will make its debut for the 2017 event.

In addition to the six haunted houses and unsettling scare zones, Fright Dome guests can experience all of the thrill rides and games that The Adventuredome theme park has to offer in the darkness and fog, including two roller coasters. Coaster-lovers will dive into the gloom on The Adventuredome’s El Loco, an adrenaline-pumping adventure complete with G-drops, gravity-defying turns and over-the-edge twists. The theme park’s second roller coaster, Canyon Blaster, takes them through a double loop and double corkscrew shrouded in shadow.

Fright Dome is open select nights from 7 p.m. to midnight Sept. 29 – Oct. 31. General admission tickets are $37.95, with additional fast pass upgrades starting at $20 allowing express line entry for all six haunted houses. Updates on Fright Dome are available online at frightdome.com.
