Franklin D. Roosevelt inspired legions of Americans when he famously said, “The only thing we have to fear is this haunted house.” Venture bravely into terrifying territory with this Groupon.

$20 for a VIP Fast Pass to the 13th Floor Haunted House and Zombieland Haunted House ($35 Value)

Fast passes enable guests to skip the general-admission line for quicker access to two haunted attractions. In the acclaimed 13th Floor Haunted House, visitors wander a haunted labyrinth, stumbling upon a chainsaw forest and graveyard with intricate mausoleums. Next, Zombieland transports the scream-weary to a city overrun by legions of the undead. Live actors and animals inhabit the space to elicit chills, though they never touch patrons. However, the intensity and graphic nature of both attractions make them unsuitable for children, and neither are recommended for those 12 and younger. Click here for dates and hours of operation.

13th Floor Haunted House

The legend feeds on superstition. Many buildings avoid numbering a 13th floor for fear of welcoming disaster or deterring those susceptible to paranoia. Yet even when the number is lacking the floor still exists, so many contractors have taken to hiding it underground. There, the dead walk alongside those seeking asylum from society as well as rats, snakes, and spiders.

When the brave enter the 13th Floor Haunted House, the elevator that meets them at the front of the line heads down instead of up, revealing a subterranean network of expertly orchestrated haunts and special effects. Hollywood-quality makeup and effects transform a 60,000-square-foot labyrinth into a world full of torment. Fear-stricken explorers run through a chainsaw forest and an asylum packed with bloody, screaming patients. From cobwebbed graveyards to a disorienting tilted room and open elevator shafts, the ghoulish settings leave explorers panting and ready to trade in their night light for a spotlight.

After the 13th Floor, groups stumble up into a second grisly site: Zombieland. This post-apocalyptic world presents a city swarming with more than 100 undead that pursue trespassers past dilapidated storefronts and street intersections, craving a meal of human flesh with a light caesar salad. Paired with the haunted underground, this panoramic experience earned the 13th Floor a spot on Hauntworld.com's Top 13 Haunted Houses in America in 2011.
