In 1967, researchers in Cambridge detected a mysterious radio signal unlike anything ever recorded. The transmission was nicknamed “LGM-1” — short for “Little Green Men” — after some believed it could have originated from intelligent extraterrestrial life.

Now, a new transmission has been detected. As you investigate the message hidden within the signal, the transmission suddenly stops…

You awaken inside a dimly lit room. The walls vibrate with the sound of strange machinery.

The transmission was only the beginning.

What an amazing room. I love this, some great things in rooms we have never seen before which means it is really fresh. The host, and owner, was amazing. We are really looking forward to coming back for the other rooms - really want to do the Christmas one as the experience was so good. 

A 'must visit' escape room!

My wife and I have completed 40 escape rooms together, in multiple cities and countries. 

This is 100% the best room we have ever seen. The hosts were amazing, really caring and gave us a very unexpected photo keyring at the end. 

The room itself was absolutely amazing, really well themed, unique puzzles that were challenging and cleverly designed.  There was a lot to do, much better with the additional 30 minutes and for the first time in an escape room (for us at least), we didn’t come away from it not sure how we solved any of the puzzles. Everything made sense and tied together well. 

I couldn’t recommend this room enough.

This is an incredibly well built room, the theming is really well thought out and the puzzles are very fitting to the story. Some of the puzzles were extremely clever!  It is obvious why this room came in 7th in the top UK rooms voting, it really is a masterpiece of building.  Hosting was superb, very friendly and chatty just as we like.

We've played a few 90 minute rooms before but this room had so many long puzzles (to us!) that by the time we ran out of time we still had a long way to go. Interestingly another couple played the room before us and also failed even though they too were experienced escape room enthusiasts.  Our lovely GM allowed us to finish the room even though we were 12 minutes over the time.

I think it was a reflection of our age and younger, more energetic 😂 escapers may love the packed nature of this room.

As a side note, it was a shame that the exit to the game is passed on the way to the entrance. It gives away the ending which should have been a lovely surprise!! Maybe put a screen around until the group is in the room, just a thought!

we really enjoyed this room! the theming was super immersive and the puzzles were thought-provoking but not overly difficult of the point of being impossible to work out. definitely would not recommend for escape room beginners!

Had a really fantastic time with this room! Lots of fun details we hadn't seen before and the story flowed well. 90 minutes was a good amount of time to get stuck in.

A truly fantastic escape room. The set design is astonishing. Puzzles are all on theme and hugely varied. A fantastic atmosphere throughout the room. So much to explore and so well thought out. Would recommend especially to smaller teams so everyone can get involved, as the room is linear. A wonderful escape room.

Really enjoyable game with lots to do and some really creative puzzles. Enjoyed the multilayered steps and immersive atmosphere / clue system. I’d recommend a small team size as the game is linear- definitely the best Exit / Cambridge Escape Rooms have made to date!

Amazing room. Having done over 200 rooms I can still say there were things in there that I had not seen before!  It's so hard to write these reviews without giving anything away, so just go and do it!

We beta-tested this so can't review the final experience, but would 100% recommend trying the finished product, which has clearly had a lot of love and care dedicated to it. Great hosting as well.

Specimen 27 is a superb, top-tier room that shines on every front. It's jam-packed with beautiful, immersive, innovative and well designed puzzles.

It's a 90min room and we'd call it fairly challenging simply because of the sheer quantity of puzzles to get through in the time, especially as it's linear. Everything makes sense and flows well, and it's clear a lot of thought has gone into balancing puzzles well even when multi-step/source, so they hit that "challenging" point without being frustratingly hard or easy.

The room looks and feels very high quality and the attention to detail is next-level. Props, scenery and tech are all brilliant and really elevate the experience to the next tier. Isaac was a great host, very welcoming and knew just when to nudge us or let us ponder a bit longer! The room has a strong narrative which, alongside a sequence-driven set, really contributes to building a particularly fun, immersive experience.

An outstanding game from Isaac and the team. The set design and build quality is next level. There’s lots to do here, it’s a linear game that kept two experienced players busy for the entire 90 mins. There is a wide range of tricky puzzles, well signposted with no logic leaps. Many, many “that’s cool” moments and lots of unique interpretations that we hadn’t seen before. Bravo Isaac, this was quite simply a joy to play!

An absolutely superb, high difficulty room. Construction quality and set dressing are extremely high quality and the puzzles are creative and challenging. Forget what you assume from other rooms, if it doesn't specifically tell you not to touch it anything could be part of a puzzle.

We take our first defeat at the hands of this room without shame.

👽The Truth Is Out There… and It’s in Cambridge


We’ve completed nearly 100 escape rooms around the world, and this company is genuinely among the very best we’ve experienced. If you’re in Cambridge, don’t miss it.

We just completed Specimen 27, and it had everything you could want from an escape room: fun, challenging puzzles that really made us think, all wrapped up in an immersive theme. The set design was impeccable, and every puzzle felt like it belonged naturally within the story.

We’ve now completed two rooms at the old location and two at the new one, and every experience has been exceptional. This is easily the best escape room company we’ve found in Cambridge and, honestly, it’s right up there with some of the best in the world.

Beyond the fantastic rooms, the personal service is second to none. The team genuinely cares about creating a memorable experience, and thoughtful touches like the take-home souvenir make it even more special.

If you’re looking for an escape room, stop searching and book here—you won’t be disappointed.

A great escape room, lots of puzzles and brain teasers. The area had a power cut half way through, no fault of the venue, they handled it so professionally, resetting aspects, letting us have a sit down, adding lost time back all whilst being very friendly and apologetic.

I enjoyed the look and atmosphere, they'd really put a lot into the rooms, the tech and lighting. Highly recommend!

A really excellent room. Despite it being very new everything worked perfectly and they have clearly very well tested the game and worked through any teething issues.

I would say this is most likely the most difficult room I've done, though nothing felt unfair, I would perceive first timers may have a rough time as everything had depth.

The craftsmanship on the room itself was amazing, and there was clearly a lot of effort put in to even the minor details in the room. Props felt sturdy and well built, no poor quality hinges or janky locks. Tech where integrated all worked well without any frustration.

The host offered the perfect amount of assistance to keep us on track, and it never felt intrusive, and clues were freely given when requested.

Definitely a few puzzles in here I'd not seen before, and new twists on old concepts. I'd say this will likely be the case for all but the most experienced teams.

I have really enjoyed every room Cambridge Escape Rooms has done so far and this was extremely fun! We actually ran out of time and they gave us more time to finish which was lovely and all of the puzzles were really intriguing and some even funny! Probably my favourite one so far and I will always go to Cambridge Escape Rooms above any other company as they are the only people I've experienced so far that have such immersive aspects to their games. I would choose all the positive tags if I could as I genuinely think all apply.
