The Butterfly Sign: Human Error is the second chapter of the first person detective video game in which we are playing as a sole survivor of a serious terrorist attack. Protagonist is the only witness of the incident and his fate depends on his memories. That’s why he goes in for a desperate measure: he takes the experimental medication called “Rammex”, which immerses him in the depths of his mind and makes him accurately recollect a chain of events, which had happened. While wandering through his own memories, the protagonist has to look for evidences and learn bits and pieces to find the guilty persons…

The main feature of the second chapter of the game is the concept of multilevel memories. Drug effect of Rammex makes the protagonist remember everything he has ever known, while maintaining freedom of action and choice inside his memories. This means that if the protagonist finds the device with Rammex in his memories, then theoretically he may use it…

The second distinctive feature of this episode is the spatial confusion inside the memories or, put simply, looped space. Some of the memories will cause errors in memory, thus creating looped space: while trying to leave the location by all means, the protagonist will make it into it again and again and so on ad infinitum. You will have to put your thinking cap on in order to solve this puzzle, to break the loop and to get out.

Explore Memority hospital and its premises, learn its secrets and restore the chain of events that took place here. Solve the puzzles and murders committed at Memority. Find clues, compare the facts and avoid tricky obstacles in your way. Penetrate into the new, previously inaccessible memories. Make conclusions and choose the correct route, because all your decisions affect the outcome of the game and influence the fact whether you can get to the truth. Thuth that was lost in your own mind…

- Excellent graphics achieved with Unreal Engine 4 – the most advanced game engine in the world. We used photogrammetry technology and high-resolution textures to create the world of The Butterfly Sign as beautiful as possible.

- Non-linear dialogues and the ability to make choices which will affect the course of the story and the ending. The progress of the dialogue always depends on your location. And you always have the opportunity to make choices, sometimes insignificant, sometimes important for the further story.

- Brainstorm your head with investigation of murders, puzzles and mysteries. The Butterfly Sign develops the player’s skills of criminology and deduction. For those players who prefer the story, there is always the easiest difficulty level, but if you are really up to the true detective, you have a variety of other levels, including the hardest one causing the game restart after a single death.

- In The Butterfly Sign, the events take place in the past and in the present simultaneously.

- The atmospheric sound. We have paid a great attention to sound effects in The Butterfly Sign. Every lamp, every water drop falling from the ceiling has its own sound. Each room boasts of its own unique ambience corresponding to its style and mood.

The action takes place in present. The protagonist, Jack, was found not far from Memority hospital, where an experimental drug called Rammex had been developed. It was created to help patients recover their memories. But the hospital was attacked. The drug was stolen, and all the staff and patients were killed. Explosion and conflagration destroyed a part of the hospital. And Jack was the only survivor. As a result of a strong explosion, Jack lost some of his memory, he remembers only small fragments of what have happened.

Jack is helped by Dr. Romanov – the chief scientist of Memority hospital and the mastermind behind the drug. During the whole game, the protagonist will be staying in a hospital bed, and all the gameplay will occur in his memories restored with Rammex. The game world is divided into two parts: the real world, where the hero is confined to a hospital bed, and the world of his memories, where he will spend most of his time. The Butterfly Sign also has non-linear dialogues, and all your decisions will affect the outcome of the story at the very end.

Necessary Evil
The Butterfly Sign is divided into three chapters. In the first chapter, Jack, walking through the alley of his own memory, becomes the eyes and ears of Dr. Romanov. The drug "Rammex" helps him do it. The main character tries to recover the fragments of his memory in order to find the ones responsible for the attack on Memority. Hovewer, the further he goes, the more he realizes that everything that happened was the necessary evil...

Human Error
Memority had been developing "Rammex" to help sick patients recover their lost memory. According to the Memority scientists, "Rammex" was able to quickly restore human nerve cells. It would have been a real revolution in medicine, a cure for many illnesses. But turning over the pages of his own mind and investigating the incident, Jack begins to realize how unreal his world is, and what a beautiful lie all this is...

Wreck of my Warship
In the end, to find the one responsible for the attack on Memority, Jack has to collect all the pieces of his memory together. He goes to the dam, where he last saw the mercenaries, but instead finds only one person who jumps down from the dam trying to commit suicide. Realizing that he has already been there, and the answer is in his head, Jack follows the self-murderer and jumps, because it’s the only chance to remember ...

The Butterfly Sign: Human Error reviews and comments

Here's a quick Warning. I'm not going to go any further in depth as far as the game and the Story itself is concerned though (!): This Game is to a very large Extent made up of the Content of the first Part. Despite these Replays, it takes less than an Hour for the Game. The "Story" barely gets on and the whole thing seems to be a Maximum of a Techdemo than anything else. Why you also ask €550 for such Content is absolutely incomprehensible. In addition, there is a bunch of broken Achivements, countless Bugs, a mediocre Translation and an "optimization" that makes this Game more exciting for my Graka than GTA 5 and Co. Here you can only absolutely advise against the Purchase. What a pity!

TL; DR: do not buy, this game is a copy and paste of the first opus. 15min of novelty for 90 already seen. This second Opus seemed full of promises, actually I hadn't looked at the reviews in detail, just the overall assessment at the top of the page that was pretty positive. Having loved the first part of this trilogy (the last chapter of which has not yet been released), I did not think long before buying this one when I saw it was on sale. Serious mistake. Let's start with the positive points. The atmosphere is always as weighful (if you have not played the first, just know that without being truly agonizing, the atmosphere through music, colors, lights and shadows, knows perfectly put you in a second State, at the limit of extreme concentration. The graphics are nice, the light is particularly beautiful and well managed, especially in the forest where each ray comes through the branches of the trees. That's all. Now let's talk about human error. This game is, at 90%, the same game as the first butterfly sign. If you played the latter and you come here hoping to advance in history, go your way, you will only have the right to two new scenes and a tutorial to explain the mechanism of the game. Apart from that, you will find yourself in front of the same corpses (Yes, you know, the guy in the toilet), the same computers with the same passwords, the same Doors closed... And all the previous cutscenes. All. In short, this second chapter is not one. For proof, if you are looking for some of the successes you will notice that all those of the first installment are found in the second (Yes, even the funny "♥ ♥ ♥ ♥ ing caps lock" or "why so many fridge?" I bought this game at €2, I feel... swindled. In short, I totally advise against it, even the few positive points above fail to catch up with the game.
