I feel a little silly for not knowing what the 'Montauk Project' is/was, all I know was that Reddit said it was a must-go Escape Room while in Brooklyn, so we went!
Boy was I in for a surprise. This room was themed so fantastically, every single room including the starting "outdoor" area was just phenomenal. All the puzzles were themed and nothing felt out of place or obvious particularly. It was a little creepy and spooky, but it absolutely floored us with its ingenuity. None of the puzzles felt unfair, and when they seemed difficult it was because we overlooked something on the way.
If you are anywhere near this room on a trip or otherwise, make a stop. You will not regret it!
