The next original haunted house coming to Halloween Horror Nights 2019 is not for those with a fear of the ocean.

The story behind the house, called Depths of Fear, is that workers for deep sea mining company have come across a race of parasitic creatures known as Mouthbrooders. As they attack and infect the miners, the mining facility’s self-destruct sequence is set off.

“Picture being trapped in a claustrophobic mining installation underwater with a countless number of these slithering monsters,” Universal content engagement representative Denielle Ricci wrote on the Universal Orlando Blog. “Your worst nightmares will come to life as these fiends spew flesh-eating acidic eggs at human hosts, and you witness miners being driven mad by the infection.”

Unlike the previously announced original house for HHN 2019, Nightingales: Blood Pit, this is an entirely new concept from Universal Creative, not a successor to an older HHN house.

Depths of Fear is the fourth house announced so far for the event. Along with the Nightingales, the lineup currently includes two houses based on intellectual property: one centered around Netflix’s hit series “Stranger Things” and another starring Universal Studios’ classic monsters.

This year’s edition of Halloween Horror Nights will feature a total of 10 houses and five scare zones around Universal Studios Florida. It will the longest HHN ever, running 41 nights from Sept. 6 through Nov. 2.
