You are in very unpleasant conditions: trapped alone in the dark room. What is even worse, there are monsters in these rooms, but you cannot see them until you meet them. And when you do – shoot them and kill as fast as you can. The darkness in the rooms are so thick that you won’t be able to see any objects, as well as walls and floor until you bring the light closer to them. Once you exit one room, you will appear in another one, no less dark and dangerous than the previous.
