Big 6 themed scarefest. Know they wouldn't have 6 mazes but still...
The smiler: Probably still end up with sanctuary for smiler
Oblivion: based around fear of falling/fear of being forgotten. Obviously with 3d effects painted on the floor to look like holes and would have to feature Lord of darkness. Ends with being trapped in a cage above a bottomless tunnel (which is really an illusion missing mirrors)
Nemesis: Phalanx are trying to stop nemesis alien that is escaping. Lots of effects including giant alien. Each person gets a laser gun and go into a maze where they must shoot at the other team who's mind is being "controlled" by the alien.
Air: hard to make anything scary out of this but maybe a scare zone with mutant birds (trying to keep with the theme of flying and can't think of anything better
)
Rita: maze where you must find your way through the dark forest and ends with the "you must escape go go go!" Announcement that means everyone must Sprint out of the maze.
Th13teen: (a replacement for TotT) the forest has begun to take over more of the park and the towers are full of wraiths and trees.
Everyone who goes into the Maze gets a fast track for the ride (or discount for one) they can use on their next visit
I know it wouldn't happen and it would mean losing the existing mazes but with the state of scarefest at the moment it might be at the point where it needs to be changed completely.
