Since I'm purposely stayed up for this announcement, here it is...

American Werewolf in London house revealed... From the HHN Facebook page:

As the full moon rises, you will learn to fear the beast.

Based on the John Landis horror classic, An American Werewolf in London, you’ll come face-to-face with the bloody chaos of werewolf attacks in this horrifying house.
So officially revealed:
CABIN IN THE WOODS
EVIL DEAD
WALKING DEAD
URBAN LEGENDS: LA LLORONA
AFTERLIFE: DEATH'S VENGEANCE
HAVOC 2: DERAILED
AMERICAN WEREWOLF IN LONDON

Here is my original list:
CABIN IN THE WOODS (revealed)
HAVOC 2 (revealed)
RESIDENT EVIL
LEGENDARY TRUTH
AMERICAN WEREWOLF IN LONDON (revealed)
THE EVIL DEAD (revealed)
WALKING DEAD 2 (revealed)
GRIMM: LA LLORONA (revealed although GRIMM was removed and replaced with URBAN LEGENDS)

EDIT TO ADD INFO: The wolves in the maze will be articulated puppets, not team members in costumes... The facade will be the SLAUGHTERED LAMB, the bar from the original movie... I'm sold!!!

So that leaves Resident Evil and Legendary Truth, providing they wind up as houses... I'm starting to get a sense that Legendary Truth isn't a house, but something else for guests to interact with while at the event...

I'll post how BALLOONS fits into this once Dr. Jimmy posts his decryption of his cryptic clue...
