There already were a few dead ends - the shower scene being one of them. I doubt that it will have changed much.
Still, great to have it back! (imo)
Can't wait for Fright Nights now
EDIT: Is it me or do all of the maze descriptions sound like there will be less actors?
"The asylum opens it's doors to new patients." - I thought that the theme was always that the actors were the patients?
Also, later on it says "watch your back as you encounter dead ends, hidden corners and eyes that watch you from the shadows"
Nothing mentions actors on the Asylum's description, in fact it seems to suggest that there won't be many.
