Go behind the scenes at Netherworld, 1 of America's top haunts

NORCROSS, Ga. — Chainsaws, soul eaters, toxic foam -- it's just another October night at one of the country's top haunted attractions,

Netherworld

in Norcross.

This year marks the 20th year of haunts, terrifying screams and fear at Netherworld.

"We have so much crazy new stuff," co-owner and creator Ben Armstrong said. "We've got these creatures called soul eaters. They are these bizarre monstrosities.They're all over the place. They're upstairs in 'Monsters.' And downstairs, in 'Meltdown,' it's a nuclear meltdown. There's missiles. There's a reactor. There's mutants. It's absolutely insane."

Netherworld features two haunts. There's "Monsters" upstairs and "Vault 13 Meltdown" downstairs.

In "Monsters," there's an invasion of horrific aliens released from the unknown. They threaten our world and only the return of ancient creatures from Netherworld’s past can defeat them. It has been 20 years since Dr. Colber opened the doorway to Netherworld and now the invasion of our planet reaches a fevered pitch in an epic war of the monsters. Experience the Flying Angel, the Lair of The Sea Witch, the Feasting Vampires and an army of hideous Soul Eaters in "Monsters."

Descend into Netherworld’s dark basement to a secret government facility filled with unnameable horrors in "Vault 13 Meltdown!" During the events of last year’s "Vault 13 Unearthed," the mad artificial intelligence Proteus seized control of Vault 13 and used its resources to capture his creator, the Mangler. Proteus now demands that the Mangler create him a “bride” or the world will be destroyed with the massive nuclear arsenal of Vault 13. Can the chaos be stopped or will mutations, aliens, robots and nuclear destruction be unleashed on an unsuspecting planet, slaughtering millions? Vault 13 includes the Xenomorphic Terror, the Collapsing Missile, the Blast Off Inferno, the return of the Toxic Foam Room and more.

"You can't describe it," visitor Austin Kunis said. "It's like you're in a movie. It's like everything is around you. You look up and there's something. You look down and there's something. It's all around you."

A number of fan favorites from the past 19 haunts are back this year. Armstrong and co-owner and creator Billy Messina have resurrected legendary characters such as the Collector, the Harvestman and the Boogeyman.

Netherworld Haunted House has been rated one of the top high-tech haunts in America and noted for having one of the best haunted house casts by Hauntworld.com. USA Today Reader’s Poll named Netherworld as one of America’s best haunted attractions.

It's open every night through Halloween and select nights in November.
