Mark as done to rate

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.

29 escape rooms

Specimen 27 was by far the best escape room we have ever done. The room itself was brilliantly themed, flowed really well and the puzzles were so interesting and unique. The room provided a good level of challenge and we had so much fun. The whole experience was fantastic, our games master Isaac was brilliant - nudging us along when we needed but allowing us to get through the puzzles on our own as much as possible. The team made us feel welcome as soon as we arrived and it is clear they really care about making it a wonderful experience for guests. The extra touch of the certificates and personalised photo keyring we were given at the end really rounded off a great visit. We live a few hours away but are already planning a special trip back to Cambridge just to do the rest of the rooms at Exit Rooms.

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.
