In the distant future, there is a mysterious scientific laboratory located in underground complexes hidden from prying eyes. This place is known only to a narrow circle of scientists working on the Experiment 50 project. The laboratory is home to 50 test subjects, ranging from children to teenagers and young people under the age of 21. Each of them has a unique superpower, but at the same time is subjected to cruel experiments testing their physical and psychological limits. All of them are in isolated white cells, where their every movement is monitored through a camera system. They are also fitted with collars and bracelets to control their powers and deliver electric shocks. Scientists have compiled a list of the top 50 most powerful experiments.

The subjects live in conditions of constant stress, their minds and bodies are subjected to harsh manipulations. Isolation, cruel experiments, as well as relentless supervision of scientists undermine their mental state. The experiments range from physical tests to moral tests, and at some point they begin to experience deep dissatisfaction, fear and despair. Most of the subjects have already lost their sense of reality and do not remember their lives before the experiments began.

In fact, there are not 50 experiments, but 51. Another experiment is you. But your number is "???" because you are either TOO strong or very weak. You are very difficult to study, so they gave you the nickname "Unknown". So now all 51 subjects have been sent into the forest for some kind of "survival game". You wake up next to a tree, still wearing your collar and bracelets. You look around and see another experiment. This seems to be Experiment 031. He extends his hand to you

"Greetings. May I ask how we ended up here? Judging by your uniform, you are also an experiment." he spoke very politely, despite this long isolation from society...

There are a lot of hidden cameras in this forest, which are being watched by scientists. You need to survive month in this place
