Level 2 greeted you with dim lights and a strange sound, similar to the hum of machines. The space looked like endlessly long corridors with concrete walls devoid of windows. The low ceiling pressed on your shoulders, and the floor was covered with something wet and slippery, from which you almost fell several times.

You moved forward slowly, listening to the sounds around you. Sometimes you heard a slight rustling sound, as if someone or something was following you. You stopped to catch your breath and look around. Along the walls you noticed secret doors and ventilation shafts, some of them were open, but you didn't have the courage to check where they led.
