We are usually quite critical of games and vary the ratings accordingly as we're reasonably seasoned players of escape games - but we can't fault this one. It was logical, fair, most of the puzzles were unique, the hosting was good, the hint system was fair and sensible with them being typed by the attentive host (Alex) on a remote keyboard but only when necessary.
There are two main objectives that need to be completed for the objective to be met and their are 3 extra objectives that CAN be completed if you want to continue subsequent to the objectives completing, so if you're lucky (as we were) and hit a day that's not too busy you might be able to get a few extra minutes to complete the remaining objectives to see how long it would have taken you (+6 in our case).
As we've completed all of the tasks we can say that they're all fair and would allow a larger team to work on independent puzzles without getting in each other's way.
It's an independent company and designs and builds its puzzles specifically for their company so most of the puzzles are unique and have less of a flavour of the "mass produced" chain style puzzles that we see quite a lot of.
A nice range from simple standalone to complex which would allow the focus of many brains but I wouldn't say it's ideal for a full team of novices to approach - fine for a team with one slightly more experienced person to guide a little more - that said I'm sure the host would be prepared to hint a little more to a novice group.
Excellently hosted, excellently built, no broken tech, everything logical. 5 stars.
PS - Forgot to say - worth admiring both toilets - they both really are quite special! Seriously!!!


Our second escape room based on a recommendation and boy what a great game, as soon as you walk in the door the building is very clean and looks amazing, the actual escape room is also well maintained and looks fantastic.
Alex greeted us and led us to Sub Terra where the three of us had to escape from, the puzzles are very good and non linear which is perfect for larger groups as the three of us were always doing different parts, time absolutely flies in this game but the puzzles keep coming and they are all very well done. We completed the main task within the hour and also managed one more bonus objective just about in time.
All in all I can honestly say that this room is the standard to which all rooms should be held to, if you've never done it, book now! My only negative comment would be the small video clip at the start of the room didn't seem very convincing but in no way did it spoil the experience.

This is a fabulous game that looks great, the puzzles are very well designed and include elements I've never seen before. I've always regretted never playing Professor Dunstan but this really should be on your playlist.

First class, very original room.
Very happy with whole experience, also did the other room available.
Highly recommended!

Loved this! Such creative puzzles that all made sense to the theming - some were refreshing takes on known styles and the use of the game environment was brilliant. Thoroughly enjoyed!

Excellent room. Host was great, puzzles had variation and challenged us. Would definitely recommend playing this room!

The best escape room in Swindon hands down. Can't wait for Co-Decode to re-open with a new room. The room was beautiful, the theme was great and the puzzles were a wonderful mixture of high and low tech. There was enough to do that we split up into two smaller teams of two. We could probably play the whole room again without repeating anything

Code-decode are one of the best escape room companies I've been too.
Firstly they let us reschedule short notice (3 days before) as I tore 2 ligaments and ended up on crutches. They were very understanding and rescheduled for 6 weeks time.
Secondly the amount of love and thought that has gone into their games is profound.
Sub terra is in my top 5 games the puzzles were original and flowed well, due to having to find 4 hard drives as well as complete the game simultaneously. You alway have direction and can break up and complete different elements.
Cant wait for code decode to reopen at there new location, going to do crew for my birthday
Reviews by escape room review sites
Sorry theme park enthusiasts this isn't a blog post or review about Alton Tower's Sub Terra ride. This is however a review for Co-Decode's Sub Terra escape room which we got to play at the weekend. Located 5 mins (Driving distance) from Swindon train station is this award winning escape room. They have two rooms here in Sub Terra and Professor Dunstan and the Search for the Ancient Statuette. We were here to play Sub Terra. You are investigative journalists looking into a tip about the mines being used for experiments and you are there to find the data that would reveal everything. Going into this room I knew nothing, not even that synopsis. I went in blind and I think that worked to my advantage.
