After months of speculation, Universal Orlando has revealed their latest frightening house; Havoc: Derailed.

“WARNING: In this all-new original house the train convoy has derailed and the bloodthirsty maniacs are loose.

Escaping them this time will be a hard feat…the “Dogs of War” return to HHN23 in this sequel house, Havoc 2: Derailed.”

Some additional information on the house was also revealed via Twitter:

“These are the things that are known: An experimental super soldier program known as the Dogs of War went horribly wrong. Shadow Creek, the base that housed the program, was lost..the DOW’s had taken it, but with great causality were eventually neutralized. Six weeks have passed since the incident the surviving DOWs are being transported aboard a military convoy train. Shadow Creek was to continue experiments en route to see if DOW subjects could be contained/pacified. 6 minutes into transport, all contact was lost.”

The original house was a part of the house line-up during Halloween Horror Nights XX.

This is the 3rd house announced during Halloween Horror Nights Reveal Week. Yesterday, Universal announced that “Afterlife: Death’s Vengeance” will be featured at this year’s event as an original, 3D house.

Universal Studios’ “Halloween Horror Nights” events have a more than 20-year history of creating incredibly entertaining, horrifying Halloween experiences that are consistently rated the nation’s best.  The events on each coast feature highly-themed, disturbingly real, haunted mazes based on everything from films to nightmares — and streets filled with hundreds of specially trained “scareactors.”

Stay tuned to Orlando United as Universal plans on revealing more information throughout the week at midnight.
