So
@HHNManics and I were discussing The Conjuring's replacement and we came to an agreement out of the blue
Alien
The unofficial code word for this maze was "Uber Fan", which David in Covenant is of the other guy who keeps having music in the film.
Aside from that, I'm sure Murdy could recycle old Alien costumes/ props and have unused props in the maze without the use of the Queen which he destroyed.
Waterworld queue is also large enough to host it. The rumor I heard was that the maze would be one that was "out of the blue" and "pleasantly surprise" both the general public and fans alike...
Again, just speculation, but thoughts?
