Halloween Celebration Update!

The Universe is both fascinating and frightening!

We celebrate the success of our last two updates and our recent nomination for the TIGA Games Industry Awards 2014. Finalist - Most Original Game and Best Social Game!

Many thanks to the Cloud Chamber investigators who are making the game a fantastic experience.


  • STEAM avatars:
    Players can now choose Steam avatar as profile image.

  • Restricted nodes:
    Unlocking of restricted nodes has turned out to be more difficult than intended - because it is difficult to get likes from other players. This means that unlocking restricted nodes becomes a little too difficult. This seems to be because players are simply commenting more than they are liking. So, to help fix this problem, we have changed the algorithm, so it now counts comments as likes for the sake of unlocking restricted nodes. This means that, in order to unlock the restricted nodes in, say Part 4, you will now need 4 players to either like something you have written in Part 4 OR comment on a post you have written in Part 4 (any combination of the 2 will also work).

  • New encoding of intro video that some players had problems seeing.
  • Fixed bug when scrolling in feed or forum. Feed and forum should no longer freeze up while attempting to load more content and should load smoother.
  • A number of changes to communication between game and server to reduce risk of disconnections. Improved error messages to help troubleshoot connection issues.
  • After some controversy about Quicktime, we are now offering QT Lite as a lighter and less intrusive alternative - as suggested by some of our forum users.
  • The detection of old versions of QT has been significantly improved.
  • Fixed bug. Downvotes now no longer help unlock restricted nodes or win "best" badges
  • Fixed a few bugs and styling issues in message function.
  • Fixed a few bugs in the "Flag" function.
  • Fixed bug. Deep links in "Top Contributors" should now work.
  • Fixed path between the nodes "missing worlds" and "It's a big universe"in part 5 (used to send players on a detour)
  • Fixed bug. Clicking tagged usernames in the forums now opens the correct window.
  • Additional minor changes to leaderboard, spelling in some nodes etc.

Well, geez... where to begin? I'm not so sure I would even consider this a game so much as a social media experiment in the form of an interactive sci-fi thriller. It definitely has the feel of an old-school FMV combined with a mysterious set of nodes, following your progression in each 'part' of the game. The experience was pretty engaging, and I was always looking to 'connect the dots' when posed with a lingering cliffhanger (to which there are many). If anything, Cloud Chamber is certainly ambitious for what it tries to accomplish, and for the most part, it succeeds. Having said this, I could really do without the social media aspect of the game. Granted, it's a cool addition to encourage a sense of community in trying to piece everything together, but here's where it falls apart (in my opinion)... parts of the game will not be available to you unless you take a very active role in the 'mini forums' I'll call them. And even then, there's no guarantee people will 'like/agree' with what you have to say, thus not allowing you to view some locked content. Bummer if you ask me. I think participation alone should be the defining factor here, but what do I know? Anywho, enough about that. Overall, the 'game' was enjoyable, and it got me thinking about 'big' things (hint, hint) that have real world meaning... almost eerily so. 3.5/5

Great concept but overall, the way they handle the gameplay sucks. They should have each node's "message board" have a max of 20 people (or so) access it. In an environment where to advance you have to get people to like your comments, it's pretty impossible when there's already hundreds of comments all saying anything of interest. The reason discussing movies works is because you're discussing them with people you either know or someone that, if annoying, you can just walk away from. This game tries to capture that by dumping you into a room of hundreds of people, some of which you may not want to associate with. Keeping the "rooms" limited, possibly making it so each group "travels" together, you form relationships with the other players and may actually enjoy the discussion.

And requiring QuickTime was just icing on the crap cake.

Quite frankly, the developers should be embarassed at calling this a "game". You watch a bunch of videos that amount to not much of anything, dont influence the goings on in the story whatsoever, theres nothing solve or play or to do except make smart alek remarks about the videos in game (why bother when we can just make them here) and hope you get enough likes to unlock other pointless videos.

My wife bought this game for both of us under the expectation that it was some sort of co-op puzzle game (see co-op, MMO & multiplayer tags, which are laughable). Personally after the first couple of videos (which didnt work for me anyway because quicktime wouldnt install properly) I just uninstalled it and gave her my login details so that she could "like" herself through the content of the "game".

This title is possibly the biggest waste of money on steam. Invest in a couple of happy meals instead. I wish I had.

SUMMARY: This game is a carrot on a stick. You will not reach any satisfying conclusion to the story. A big deal for a completely story driven game.

I have played this for more than 30 hours, unlocked and viewed all content, was active on the discussions (more of lurker, but had 30+ posts as well). I did not want to review the game till I was sure I'm "qualified" to give an honest review.

I'll first describe how the game works. It's a "massively multiplayer story game" where you access a 3D database that is presented in the form of 10 chapters, each with a sequence of "nodes" for you to investigate, each node containing something to drive the story forward: a video (with human actors), text, portions of documentaries, letters, diary entries, photos, etc, The story revolves mostly around 4 individuals portrayed by human actors and is presented as a Sci-Fi mystery. The multiplayer aspect comes in play in these nodes. Once you're done checking the content of the node, you may choose to participate in discussion with other players. As in a forum, you may post a discussion or reply to an existing discussion of the node. You may also like/dislike individual posts. Liking a post rewards the post's author. In each chapter there are locked nodes accessible only after receiving a certain number of likes. This number increases the deeper you get into the game. This feature encourages players to participate in the discussions to piece together the story.

As to why I cannot recommend the game, there are reasons pretaining to the story and there are technical reasons. In regards to the story, it starts pretty strong and you feel that you want to find out where it will all lead. Very positive first impression. Unfortunately, with every passing chapter, the story grew more cryptic, secrets were piled upon secrets and nothing was resolved with clarity. The biggest revelations usually come in the video clips with the human actors, however those are aren't very common and it's aggravating when you finally reach a video node and discover that it's the same video you saw in the last chapter, with a few more seconds added in that have no real bearing, nor provide any revelation.

You will spend hours agonizing over blurred photos, spliced video frames and cryptic doodles, all because you think that a revelation is just around the corner, but you only get buried deeper and deeper into the mystery. It just feels like the authors threw a bunch of cool ideas together and presented it to their audience, thinking their audience will be satisfied filling in the gaps. I don't mind a good open-ended story that stimulates discussion, but this is just a skeleton of a story and towards the end of the game major plot points are never resolved. You conclude the game with more questions than answers.

As to technical issues, the game prouds itself on its innovation and creating this new format of storytelling. I do commend them for it and I appreciate it when developers come up with new ideas in the increasingly saturated games market. However, the format is broken. It can be fixed, and I believe it can work, but in its current form it is broken:

1) Discussions are mandatory to unlock content. That's really cool, it makes people participate. However, by the time you'll probably play it, most of the nodes have been discussed to death. There is nothing useful you can add. You will struggle to find something of value to say, yet you do have to say something if you want to unlock content.

2) Liking AND disliking both unlock content! This is probably a bug, but IMO it is a major bug. It allows trolls to spout aggravating posts which people will dislike (helping the troll unlock content) while thoughtfull well-writted posts get buried.

3) There is an activity feed that gives you notifications when people like a post of yours, comment on a post you liked, reply to your discussion, etc. This feed is broken. It only allows you to see about 15 notifications, the rest won't load and thus you will not find out what people replied to you. This is in a game that focuses on discussion as a primary form of gameplay. I have reported this (and players) to the developers, but nothing was done about it.

EDIT: Point #3 was addressed (19.09.14)

I was honestly enjoying it up till around the middle. Towards the end I felt the excitement fizzle out of myself and fellow investigators (you will see familiar names as you progress). All the investigations we did never really got us to anything concrete and nobody can claim to know what the story is really about, it is just theories at this point.

My suggestion to the developers is to fix the technical issues and rethink some of the social aspects in this game and come back with a story that actually has a plot, climax and ending. They are on to something with this idea, they are just not there yet.

Cloud Chamber is a strange beast, it’s an ARG (Alternate Reality Game, for those that don't know) that isn't an ad campaign about strange signals coming from someplace unknown. It focuses on a fictional laboratory in Denmark and the daughter of the institute director in her search about her mother's past and her research in strange phenomenon that ended with her death. Gameplay is watching videos and reading documents and discussing them with other players in the in-game message boards. There is an upvote system and helpful discussion is meant to be rewarded. The acting does its job, the actors are definitely not 90’s FMV tier, but it’s not exemplary. The story itself is interesting enough and any of the possible reasons behind everything are potentially interesting and not pants on head stupid.

There are flaws in the execution though. You're gated off of content due to the upvote system, you need certain amount of upvotes to access them and you're not guaranteed upvotes, especially because people tend to have already asked good enough questions. The other big potential flaw is that if you don't get into this game now, you will most likely miss out on everything. Seeing is that an ARG is all about the mystery once the community solves it, it’s essentially over. (It hasn't yet though) So I really don't see this game having real lasting appeal to make it to a Steam Sale, could be wrong though.

Overall I enjoyed the experience, though it’s definitely not for everyone and it’s not a mind-blowing must play game or anything. I do appreciate that the devs tried to do something different when it comes to game narratives, even if it have its flaws. I recommend it for people that are up for something different and unique, but as I said I have a feeling this game will lose its impact before a sale rolls around unless the devs actively update it with more material, so I don’t think a lot of people would be interested. Still worth getting into now though.

From the beginning Cloud Chamber has introduced me to a new form of gaming, it's an immersive play style that captivates its players into an intelligently designed world. The community as a whole is great, I doubt you will find many other communities that present themselves to be this "unified" and who have achieved so much in such a brief time.

The developers (Investigate North Aps) have expressed a keen interest in involving themselves within the community, to the benefit of improving the game, through integrating the thoughts and ideas of community members. I was surprised that the development team did work so effectively and efficiently in such a short time to overcome any quandaries that community members have faced and have already began to make improvements to Cloud Chamber.

The creative team behind all this is also very active within the community, answering questions, discussing improvements. I have found that they are not only working for the progress of the game, but also express an extremely friendly and dedicated passion towards the entirety of the community.
Investigate North have proven that they are not money orientated nor avaricious, I truly get the feeling that they want to please us in any way or form they can and believe me, they do.

The game can be slow or fast-paced, it can be tailored to your play style, and it's whatever you make it. For instance whenever I find a new clue, I'll drown myself into research about said clue, while others go through it at a much faster pace, you can play this game the way you like. That being said I find that the game urges me to play more and more as I progress, as with this type of game you would believe that it can become repetitive, however through every single event of playing Cloud Chamber, I have felt that the story has only pulled me in deeper and deeper.

Personally I stopped reading comments from other players, first I write my own speculations down and only after that I start reading what other players have to say. Which is often jawdropping due to the higher levels of intelligence I have witnessed within the community. I have witnessed that everyone has their own unique way of developing and concluding the ideas and evidence they have found from the events within Cloud Chamber, not only this, but I find that it is beneficial being able to compare and contrast my ideas with that of others, making the communal aspect of Cloud Chamber an integral but also distinctive part of the game.

This is not your average gaming experience, trolls, racism and swearing do not exist here, instead Cloud Chamber pertains to a much more mature audience, in which I can work together with people who also want to dedicate themselves to an enhanced gaming experience. That's something I rarely see in any type of game and it's what sets Cloud Chamber a universe apart(pun intended) from the rest.

In the end I'd like to suggest this game to any person that likes to think, re-think and think some more. Space enthusiasts, Indie lovers, sci-fi fans, fantasy geeks, daydreamers, philosophers and just most gamers in general are up for a treat with this little gem.

Storyline (so far) 9/10 (I'd love to give a 10, but there's always room for improvement in any game).
Graphics/Visuals 8/10 Original, never seen anything quite like it.
Audio 8/10 It's either your taste or it isn't, nonetheless it's great and really adds to the experience.
Community 9/10 As mentioned before, the community is one of the best I've ever encountered.
Innovation 10/10 For an Indie developer to take such "risk" shows balls, and it turned out they've put their money on the right bet.

As a last note, the game requires Quicktime (mentioned on the storepage) which many people didn't realize.

Okay I am really noy sure where to start here. If it would be a (short) movie and i would have seen it in cinema or on TV then it would be a good movie. After the end I am still not entirely sure about what happened but I think thats up for everyones own interpretation. I would call it a science mystery thriller.

The whole "game" has 10 chapters and in each chapter are about 5 to 15 parts of movie, pictures and writings each which gives clues to the story and unfold it more and more as you go through it. Some parts are locked though. For every part there is a comment function and players can leave comments which can be up or downvoted by other players. You can sort the comments by latest comments and most upvoted. You can unlock the locked parts if you get your comments upvoted, which I think is a downside. I left plenty of (I think) good comments and haven't unlocked any of the "hidden" parts yet.

I can only recommend this adventure though. It leaves me with something only few movies do, to think about it afterwards and what all that means. I am inclined to go through it all again to see if I can find clues I haven't noticed before. Maybe there is something like a definite answer to the question which keeps me hooked in this adventure, maybe I haven't found it out yet. But I think it may be deliberate to leave questions unanswered.

Pro: - Good actors which have an amateur touch to it which makes everything more believable instead of pro actors
- Well written story with a neat amount of science accurancy and a big mystery feel to it
- comment/upvote function to unlock "hidden" parts

Con: - comment/upvote function to unlock "hidden" parts
- relatively short
- a few parts are hard to navigate to/click on
- potential spoilers in ingame comments

I've become obsessed with this game. The conspiracy! The theories! The mystery! The... *garbled sounds, distorted voices saying unintelligible things*... murder? *bzzztflktktk*

The community is great, so far no jerks trying to spoil everything, and the format works very well... much better than I'd expected. The only thing missing is an in-game web browser because it would be nice not to have to leave the game environment in order to research some of the things that come up (and no you don't HAVE to research anything... but it's more fun that way).

I can't wait for a season 2.

For those of you that have an investigative mind and think yourself a bit of a Sherlock Holmes then this is the perfect game to practice with. Grab you magnifying glass, done your deer stalkers hat and come inside!

In Cloud Chamber you are part of a big investigation, looking to unravel a mystery and a narrative - and get invested in characters.

This game is fantastic for those who understand what it's trying to be, Cloud Chamber is about investigation, it's about time and collaboration and about having a sense of gratification in finding a clue or link.

As Every time I clicked on a node, I could feel an urge to don a checkered beret and smoke a pipe while following footsteps in the dust, I felt like a valid investigator.

The acting and story telling within the game really sets it apart and helps to immerse you in the action, but what makes it really interesting and enjoyable is the player interaction. Reading what other people think and what they have found makes you feel like you are apart of something bigger and maybe things are not quite what you first thought them to be!

When people start jumping in and join in on the forums, that's really when the game is going to take off - It is a Multiplayer Investigative Story Telling Game after all!

I recommend this game not because it is great, not because it is excently made, merely because there is nothing quite like it. It is an amazing feeling watching an ARG (Alternate Reality Game) video and analyzing it for clues. Then you compare your clues with others from all over the world working together to solve a mystery. You find yourself having lengthy discussions about every little part of the video and noticing things that you didnt the first time thanks to other peoples posts. I recommend you pick up this game for three reasons, first it is something unique and new, something that you cant experience anywhere else. Second, It is quite fun and the story is interesting, and the videos and clues are all relatively well made. Thridly it supports the devs and helps bring about more games like this, games that are completely unique, In the end I ask one question "What is the signal?"

Just before this game was lauched I listed a number of hesitations that I had with the concept. The first being the social media aspect to the game. So far I can say, this really works. I found myself bouncing through the first three videos combing through the evidence and trying to create my own theory as to what was going on. I've also found myself discussing ideas and with the help of others shaping my understanding.

This game isn't for everyone. It is about throwing ideas out there and sharing thoughts. It's like a massive conspiracy taking place before our eyes and we're trying to put the jigsaw together. It feels so real because of that.

This could be the next logical step for the Found Footage genre of films. It's really immersive because of that. Interactive media just took a very exciting step forward.

Dislaimer: review copy submitted by the developer.

Cloud Chamber is unique. Hella unique. It's a sci-fi mystery that all the players work to unravel together. You go through looking at pieces of data and discuss the files as you uncover more about the world. It's like an alternate reality game, but one having nothing to do with marketing.

I am very happy that I purchased this game. Going in, I was a bit skeptical. Now I'm an addict. 5 hours in, my husband and I have been tossing thoughts, ideas, speculations, and conspiracies all over the place. There are so many questions to ask and try to answer. Some answers come along eventually, yet others are still mysteries. An intellectual game at its best!
