Deca — is truly a scary game that tells about the transition in time of our hero. We start the game with the fact that we are on the territory of a psychiatric hospital, in which patients are currently staying. After that, walking along the corridor, we fall into an incomprehensible unconsciousness and wake up already in the ward, which is half destroyed, everywhere it smells of corpses, and the environment, consisting of equipment, resembles the 1960th year. Our heroine understands that she needs to escape from the psychiatric hospital Deca as soon as possible, so she decides to get up, despite her health, and run away from here. But it’s not that simple.
