The story

Players collaborate with each other to explore, investigate and discuss the fragments of information they collect on their journey through the dataworld, writing the story themselves of a young scientist, Kathleen Petersen, who risks her sanity and betrays her father to save humanity from itself.

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
