ATLANTA: This fall, the gates of NETHERWORLD Haunted House burst open once again for its 29th Season of Screams, cementing its reign as one of America’s most iconic haunted attractions.

“Each year we push ourselves further,” said Ben Armstrong, NETHERWORLD co-creator and industry veteran. “For our 29th season, we’re going bigger, longer, and more overwhelming than ever before – these are some of the most massive haunts in NETHERWORLD’s history, covering the combined walking distance of 10 football fields. We want guests to feel completely transported…like they’re running through a living nightmare.”
