Pros and cons are probably the easiest way to help you make a decision on purchase MU Complex.

Satisfying Linux command line based game play.
The puzzles are satisfying:
-Real world information puzzles that requires you to use Google.
-External MU Complex owned websites to solve puzzles are a nice touch.
The story is interesting.

Having to retype commands many times over when stuck on a puzzle (A note pad can help relieve this)
I don't really like the sound track but it can be muted.
Everyone seems to save their passwords in a document called password.txt
While the "About the game" section leads you to believe you will become a "real hacker" I doubt this game will give you any real world hacker experience.
The console window does not support the mouse scroller

Overall the cons are fairly minor and don't take anything away from the experience and I consider the game put together well. I recommend this game to people the enjoy puzzle games and visual novel style games.

Constructive criticism:
I think there is a missed opportunity to support dual monitors.

TL;DR: Great concept, lousy execution.

Before I begin, you should know I'm coming to this game from the perspective of an adept Linux user. The terminal is where I live. So when I read that we'd be using "actual Linux commands" to solve hacking puzzles, I wouldn't click buy fast enough. Unfortunately, "actual Linux commands" essentially meant ultra stripped-down versions of ls, cat, ssh and sometimes sudo.

The puzzles themselves were decently creative, but way too simple. About 90% of the puzzles could be solved with some variation on the form (1) read the emails for clues then (2) type in the password to unlock the username / password for the next computer . About half the puzzles require a simple Google search which seemed cool about twice before it got annoying. Overall, the puzzle aspect felt formulaic and underdeveloped.

Some nice work went into writing the emails between the office workers and I enjoyed getting to know the story through that device. Everything from the story/atmosphere perspective was VERY solid.

I think there's a ton of potential in this type of game, especially for teaching people about how to use Linux. It just needs more work to make people really have to work to solve the puzzles. Codesleuthing is tons of fun, but it just doesn't feel fair when your puzzle is as simple as translating morse code or maritime signal flags. Also, there's no reason this game shouldn't have had a better terminal emulator. More terminal options would have meant more complex and satisfying puzzles.

Overall, it's a fun diversion for a couple hours, but that's about it. It definitely isn't $9 of entertainment. I think this developer is definitely on the right track and I look forward to their next release, but this game can easily be skipped.

I am a software engineer and a gamer, so this game immediately became a 'must buy' for me. Having played through the first two episodes (can't wait for the third), I can say that this may be the best hacking game I have ever played.

The game really does make you feel like a hacker, as you're dropped onto a linux-like environment with a terminal and desktop. All while you have a really sweet electronic music playing as a part the games sound track. If you wanted to feel like Neo, this game is the one.

The puzzles are really sweet. Why? The game forces you to use "outside resources" to solve some of the puzzles - ie: using google maps, searching wikipedia to figure out musical notes, all to deconstruct a timed puzzle. Oh, and yes, the puzzles had me streaming all kinds of profanities at times - a good sigh the puzzles are well made.

Unlike other hacking games, this one is fully voiced. THANK YOU.

The graphics are clean, minimalist and sharp. Exactly the right combo for this sort of game.

There is a 'good' story for what it is, and the cliff hangers after each episode have me yearning for more.

Buy this, even if you're only mildly interested in the subject of computers, or if you're just into puzzles. Even if you think the game might feel a bit to challenging, because each puzzle solved is rewarded with an amazing sense of joy.

A breath of fresh air for the genre. At one point I had google, excel, a piece of paper and pen to solve the game's puzzles. Good fun!

Big Review Update:

I love this game, the way you have to think way outside of the box to solve the puzzles is just amazing. I definitely want more games like this.
And to clarify this version of the game has the first and second episode of MuComplex that where previously on kongregate.
I do not know how a possible release of a third episode might be handled.

As much as I love the game, the way the steam release has been handled was pretty bad. The free version was shut down without much prior warning and for the way the port was done its a bit expensive.

About the Port:
It's basically still the same game as before. to my current knowledge only 2 things were added(hints that unlock after a certain time and some additional puzzle after beating both episodes) No gamechanging fetures were added. They even removed something substantial(ctrl+v) which made one of the puzzles difficult to solve.
Some features that could definitely not have hurt to add would be to make the terminal resizeable, allow you to open more than just one picture and let you resize and move those freely on the screen. Also there are no game options of any kind, you just get a small button to turn the complete audio on or off. It's pretty disappointing.

At last some praise:
*love the concept
*voice acting is kinda ok
*the end of episode 2 has a nice little cgi cutscene
*there are a lot of emails that are not necessary for puzzle solving, they add a nice atmosphere to the game and let you look into the workings of the mu complex

I (probably a mistake) went in expecting a "hacking" game, in the wake of games such as Uplink or HackNET. This... is a completely different thing. It's more a series of stale, extremely simple puzzles or mini-games that you just have to complete to progress.
Mu complex also tries to use clever "real life" puzzles - which would be interesting if this genre hadn't existed for more than a decade (see Ouverture Facile for instance).

In addition the story is not only boring, it's also infuriating. You can see the twist coming from a mile away - hours before finishing the main game. Yes this means there is a post game. I didn't finish it. It started feeling like a grind. The thing is : cracking codes can be fun, but most of what Mu Complex asks of you is not to crack the code, it's to apply the formula. It's not enticing.

So what's left? There is no real music - just background atmospheric. It becomes agravating fairly quickly. The UI then? Yeah the UI is pretty good. It works, it looks slick and it's appropriate and functional. However the controls (typing really) are not. It feels very frustrating to have the commands available to you change on every single stage (computer), spelling out the answer for you. What made you feel clever in a game like HackNET was figuring out what to do with all these tools you accumulated. Nothing of that challenge here - we give you only what you need so that you're not lost.

I wanted to love that game, I really did. We don't get enough hacking games and these can be so fun. But a hacking game this is not. This is a series of mediocre puzzles, under a decent looking coat. There's definitely potential, but it's not there yet.

Great storyline, some onteresting hidden details or clue (i probably have missed a lot of them, but then again, they are hidden) give the game a verry interesting atmosphere. Most of the game can probably be done "simply" by people used to both puzzle games and coding, but for someone who's new to both it can be quite challenging (which make it even more rewarding to find the answer.
In my opinion it's worth the cost.

This game will forever remain as one of my favorite game among all the others.

This is one of the few text-based games that could get me hooked right from the start. Mu Complex had me searching through Twitter, to scrolling through different color's hex code, to scratching my head while trying my best to decipher vigenere-- it has been quite a ride.

Yes, this game has nothing to do with real hacking, the most advanced "hacking" you'll ever be doing in this game is reading through emails to find hints of another computer's password, but it's very much worth it. I've played this other game on mobile called Hack Run the other day, and this game is very similar to that as well. I love both games quite a lot :)

I admit that I bought this game on impulse just by looking at screenshots, but this has been one of the best impulse-purchases i've made in a while.

Edit: At the time as I wrote this, I had no idea Hack Run + Hack Run Zero was on Steam xD

Definetely a fun little game. The puzzles are interesting and its always fun to have games that does stuff out of the game (like doing google searches, map coordinates etc). The command lines based gameplay also provides a "geeky" feel to the gameplay. The endings and secrets and also pretty amusing (though I kinda expected the standard ending, too much of Portal and AI's that feels a lot like GLaDOS I guess :P)

As a computer science student this game feels me with joy, it has a linux based command terminal and rewarding puzzles.
The story is also intriguing and quite fascinating, but above all you use real world knowledge and encourages you to learn new things using the internet. From data encryption to philosophy this game is 10/10.

I do not know where to begin, this game got me hooked right off the bat, tho it was only the beginning, I can tell it is going to get harder and harder as it goes, I only hope that more story line develops as I progress through it.
But here is by first experience with the game.

There is not a whole lot to talk about but you get to open files, switch computers, run things as admin. it seem pretty basic, but somehow it makes me want to find out where this is leading to, why am I accessing these computers that are 60 years old? but on the note of this review, let us move on to the Pros and Cons

- Simplistic yet professional design
- Innovative puzzle style using text style interface
- Open close move windows, files pictures
- Puzzles that make you have to think and research files and commands to move forward.
- Difficulty gets progressively more challenging

- No option for music control, which means very little (see next con)
- No music during game play, just repetitive sounds that get old REALLY fast

as mentioned since its a simple style there is not much to comment on yet, as since this is just my first look, it may change and I will add edits to this as I find out more things.

I would say if you like unique puzzle games this should be one you pick up and play but I cannot say much about story yet because I am not sure what it is yet.

This game is a lot of fun. Almost makes you feel like your in a rush to get through the firewalls, finding all the passwords, configuring the cameras, understanding the network layouts, and everything else that comes up. Definately one of my favorite puzzle games I've ever bought on Steam, and HIGHLY recommended for those looking for a mind-boggling challenging puzzle game.

As some are quick to point out, Mu Complex is not a 'hacking game'. There's no frenetic action, load balancing packet transfers across multiple servers or firewall cracker mini-games. Instead, you're an e-spy, learning just enough about your targets to steal their secrets, before moving on to the next-to-be-victimized terminal. So Mu's not a 'hacking game', it's actual hacking.

The puzzles grow fairly linearly in difficulty, beginning with laughable non-effort and culminating in multiple notebook pages of nightmarish chicken scratch. Like many adventure games of the internet age, Mu requires that you befriend Google, researching beyond the in-game assets. Accordingly, the developers have created a suite of real world, online content to further your immersion into the complex world of Complex.

Unfortunately, all of that outside browsing accompanies an odd, recurring bug. Alt-Tab'ing out blanks the game screen, seemingly erasing your progress. Resizing the game screen fixes the problem immediately, but I suffered through a bit of 'close-and-replay' before stumbling upon that solution.

Overall, using only minimal interface and unobtrusive music, Mu Complex creates an appropriately tense atmosphere as you dig through the sins of the past. The simulated voice acting is sometimes soothing and sometimes unnerving... So much so, in fact, that when I updated Windows 10 recently and the screen displayed HELLO in big block letters, I flinched... Play the game, you'll understand why...

It took me 6-7 hours to complete the two standard episodes, having read through every accessible message and taken the relevant notes. Beyond that, there is additional content that I will refrain from spoiling, so the total package well justifies the current $9 price point. For the fellow Achievement Hunters, it took me 21 hours for 100% completion, with one particular achievement requiring a lot of patience... you'll know it when you see it... so have a book handy.

Mu Complex in a few words:
*Starts with no clue what to expect*
*first mission*: "What the hell do I need emails with terms that sound like Hebrewish to me for?!"

*30 minutes later*: "Maybe I could try see if Google can help a bit?"
*1 hour and 40 Chrome tabs later*: "yeah it definately helped a bit"
*8 hours later*: *looks at spreadsheat I used for it*: "This probably looks like Hebrewish to others"

10/10 would rate a small duck again
