Amazing room - fully immersive from the get go (which is absolutely on brand for Deadlocked) which reminded me of some of the TERPECA rooms we have done in Barcelona.
This is a horror escape room BUT it has actual proper puzzles so you need to try and concentrate while feeling tense. The styling of the room is well done and the way you are introduced to the room means that the guidance from the GM does not break the immersion at all - it all makes sense.
The story is great with top notch acting, a few moments of real terror on top of the continuous sense of dread. There is a lot to do and there is some crawling involved, but it is well padded and spacious (we are both over 6ft and had plenty of room) but make sure you are suitable dressed for this.
Not for the faint of heart but, as someone who doesn't like horror rooms (I know...) I am so glad I played it. Don't let the horror theming put you off if it's not normally your thing.
So much fun, I wish I could delete it from my memory and play it for the first time again.
(Play the Time Machine while you are there - it's a fun room with some clever ideas that I have not seen elsewhere)
