You wake up in a crappy and very strange place, like an old factory or warehouse. You are locked in one of the rooms. You don't know how you got in here and what to do next. Suddenly, an unfamiliar and arrogant voice from the loudspeaker orders to obey him and follow the rules in order to survive and get out of here. Everywhere around is semidarkness, confusion, and loud clinking sounds are emitted. The locals know you're here. Death is inevitable if inactive, but outside the room is also dangerous. There is only one option, to move unnoticed and avoid encounters with monsters, because health is limited.
