Netherworld is distinguished by having developed an original theme which was not based on popular movies, such as slasher films, but rather on a unique storyline.

In 2000, a third event was added at a remote location for one year, called Bloodfeast, a replica of a Medieval Torture Chamber.

Netherworld has always created original monsters and props, rather than using movie or television intellectual properties, as many other haunted attractions customarily do.

A number of actors also stalk the queue line and Midway before the haunted house actually begins, starting the experience the moment guests get out of their cars.

Rob Zombie's Halloween II film also rented props from the event and used Haunted House staff.

Many Netherworld crew are now involved with production of the AMC TV series, The Walking Dead.
