Door One was Trailers, not a surprise. There might be some minor changes to the scenes but nothing notable considering how quick you go through each one.
Side note: Saw people complaining on Twitter saying why are they announcing a maze we already knew was returning. They wouldn’t announce anything new straight away, common sense?
The doors thing is confusing, if the doors were part of the maze, they wouldn’t tease each video as door one (and I assume there will be door two ect ect)
Is it just a way to market each scare at fright nights?
