Something new and unique. None of the existing genre definitions fits this game. A little bit like an interactive David Lynch film. If you hate linear stories and being forced down an path in a game this one is for you

Not what I expected at all. It gave the appearance of a hacking game of sorts. A pleasant surprise when I actually started playing.

You are a person surving the web as one does, when you stumble on a video log. Captivated by the story (It really is an interesting story brought in a very convincing manner) you start digging deeper to find out how it continues, while talking to other (real) players online using a forum-like chat debating about details, and more often than not see others over-analyzing the problem.

A great story, an captivating way of delivering it and an interesting approach to gameplay mechanics make this a gem.

There are, however, a few problems. First of all it uses Quicktime, which, given the sheer amount of videos, causes crashes here and there (don't know why, but have the feeling memory isn't cleared properly). Second, as you talk to other players on a forum-chat combi thingy (ingame though) remarks and details are repeated over and over again, speculation and over-analyzing and the inability to click away messages makes it annoying to go over the messages, not to mention people talk in clip 1 chat about things that happen in clip 2...or 42...

I am familiar with 'treasure hunting' in real life, where a group of people tries to take pictures, collect information or items in the search of a pre-written story and this reminds me exactly of that. The characters are real, and so are the settings. They used very little rendering, but a lot of effects, which look great by themselves, but at times steer the players in a completely wrong path...

I would recommend this with lights off and headset on for full immersion. Definately worth the try.

If you like a good story line and don't mind interacting with other people this is a truly great game. I'd recommend playing with another family member though so you can discuss with them as well. A little strange to get used to at first but once you get used to it, its good. Also for people without much time, you can login, look at a few things, post a few messages and log out. Try it! You won't regret it.

Decent acting, a story brought to you in tiny quicktime video bits and a facebook-like gameplay experience. You post, you comment & you like someone's status hoping that someone will like yours or comeent on your posts so you can unlock the restricted nodes in the maze.
It's a nice experiment but the facebook thing isn't really doing it for me. As is the story so far.

The game is basically:

I find it very difficult writing a recommendation for this game. Not because the game isn't good. Nor is it because the game is bad.

It's because I know this game isn't for everyone. If there's one thing I can say with certainty, is that this game is unique.

The game (and I use the term VERY loosely) is about engaging in a story and trying to unravel its secrets with the help of other players. Yes, that's about it. There are no quick time events. There's no score. There's no life. There's no end-boss. There's just a story, and whatever you feel like doing with it.

I know some people will shoot through said story, be slightly perplexed and unnerved, asking "is this everything?", annoyed that there's seemingly nothing else to do but watch some videos and look over some photos.

The reality is the essence of this game is the discussion that follows every piece of evidence that happens in the forums directly tied to the game.

This certainly has some flaws (like the need to have upvotes to unlock certain nodes - or evidence if you will). And I fear if the game will be as fun when the people move on (this isn't an MMO, there's no grind, there's little to keep you besides your own curiosity)... But for the time being, the experience is unique and... fascinating. At least to me.

As I wrote - I cannot say if you, dear reader, will enjoy the game. I do now know you, after all. I cannot give you a definite "yes" or "no". But I can promise: you haven't seen anything like this before.

Not exactly what I expected but I definitely enjoyed the experience. Though it is not groundbreaking, it opens up new perspectives for this genre - which I'm not a fan of but this game still managed to crave for more.

However, I felt they could have achieved more with these ideas. The social side didn't work well for me, as people need to get likes so they post but they don't feel the need to like other's posts. Unfortunately onnly a few realised you have to give to recieve. Maybe some clues should be locked not until you get certain number of likes but until you like other posts.

About the story... It is interesting, mysterious and has enough threads that everyone can find their favourite. Mine was the scientific part where the story really tries to be as realistic as possible. I expected less science and more fiction but this way you have more chance to uncover the mystery, not just "It's magic, deal with it". There are other interesting aspects of the story like whether to trust others, (the fear of) going insane, fighting with the obstacles in research, etc.

Despite all its flaws, I enjoyed this game and I hope that it was just an experiment from the developers with new ideas, and they will follow this path with more titles and more creative ideas.

Что я моу сказать об этой игре, это не игра это своего рода чат где люди получают информацию их мнимых листовок "Хмм.. Вот смотри здесь очень страня закарючка она поможет мне и я буду всем утверждать что я прав". Что можно сказать про контингент этой игры. В основном это англоговорящие люди, субтитров нету и всё приходится воспринимать на слух. Есть много непонятных ситуаций за которыми ты лезих в браузер и начимнаеш про это читать. Но если кто-то смотрел National Geografiс то там много раз показывали про всиленые и т.п.

-Звуковое сопровождение ( На любителя)

- Отсутвие субтитров

Оцена 3.7/5

P.S Верьте в космос.

Quite likely the most cumbersome way of getting through a linear story I've ever experienced. Would probably work as well as single video with comment at timecodes.

But if you like a 90s-style vision of storytelling of the future, including tiny quicktime videos, this is probably your thing.

No gameplay whatsoever. Buy this for Quick Time 6 or QT Lite if you need one. Just a fancy video player with a comments section.

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?"

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.
