Ready to venture into the Upside Down? The eerie otherworld will be open for visitors this fall when a "Stranger Things" maze debuts at Universal Studios' Halloween Horror Nights attraction.

The 2018 maze will be based on Season 1 of Netflix's supernatural drama and "bring the chittering, predatory Demogorgon to Halloween Horror Nights to stalk unwitting guests as they encounter iconic scenes, characters, and environments from the mesmerizing series."

"Stranger Things" creators Matt and Ross Duffer and producer Shawn Levy are working with the Horror Nights designers to build versions of Joyce Byers' home (including those flashing Christmas lights), Hawkins Lab, and of course, the spooky Upside Down woods.

For fans of the show, it'll be a scary treat while waiting for Season 3, which does not yet have a release date.

Halloween Horror Nights has done TV-themed mazes before, like a "Walking Dead" one that was turned into a permanent attraction at the Hollywood theme park.

The "Stranger Things" maze opens September 14 at Universal Orlando Resort and Universal Studios Hollywood, and September 28 at Universal Studios Singapore.
