I absolutely love going to the rooms at The Secret Chambers! I've officially done all of their rooms and every single one has been a blast. The scenery is always intricate and well done, the puzzles are great, I love having an interactive host and the storylines are awesome. I even love all of the different effects that I've seen in the various rooms - exploding dynamite, spells, cannons, and so on. They also have some very technically intricate devices in the rooms, too.
I can't recommend them enough and I'm hoping that some of their planned rooms open soon - I'm definitely looking forward the Polybius, The Dragon Hoard, and more!
