You and your friends have snuck in to the laboratory of world revered scientist, Professor Wotamesser, in the hope of finding the ingredients you need for your practical jokes.
You’re just reaching for the bottle of snake venom when you accidentally knock over a bubbling flask, releasing an evil smelling gas into the air. Oh no!
Will you be able to find the antidote before the fumes finish you off and will you complete the science experiments and escape before the professor returns to discover who has messed up her life’s work?
The clock is ticking…

I think 4 was the right size team for this game - although it's non-linear, there's only so much you can do at once as you kind of need to know what everyone else has done in order to get the final escape. You really need to trust your gut - if you think it might be something, have a go! This room really made us think; there are so many puzzles and codes that everyone should get at least one thing.

I found this room quite overwhelming and think it's probably better suited to larger teams. We had a good go though and escaped with 5 extra minutes and some clues. This room contained some very clever puzzles and some surprises along the way. The hosting by Tessa was great again. Thank you.

A taxing room, so much to do and nicely themed. Paniced a little bit at one stage, but we got that back under control.

Reviews by escape room review sites

Newly opened in Oakham, One Way Out’s first game had only been running a couple of weeks when I tried it, earlier than I’d usually visit a new game. While the name Gas Alert might suggest something industrial maybe set in a factory, it is instead set in an academic laboratory with a setting that instantly reminded me of school chemistry lessons.

Many escape room themes have you heroically saving the day, but in this one you’re extricating yourselves from a mess entirely of your own creation - a...

This felt like a game of two halves for us, we loved the first half but struggled in the second. Either way, this is a solid game with a massive space to explore!
Gas Alert shines with authenticity and passion for the subject
A tough but really immersive room that will challenge any team. If you want a real test take it on as a pair or bring a larger group and tackle the game together. Either way, make sure you go along as Gas Alert is well worth the trip to the smallest county in England.

For those who want to get together for some games. Try and keep them north of Oxford and south of Manchester but outliers are ok if we all want to do them!
