The party slowly treads down the shaft, picking their way carefully through the dark hazardous tunnel. The dim lights from the few maintenance bulbs barely illuminate their way and the musty air feels thick around them. Underneathe their feet the metal creaks and groans, causing them all to break out in a nervous sweat.
Finally they reach the end of the shaft. Another small door like the one they entered. "Through here", Johnson says, he opens the handle then pushes the door open with his foot, moving into the room with his rifle raised and his LED light on with the grace of a trained soldier. He sweeps the area then puts the rifle on his shoulder. "Those creatures must have went through a vent on the shaft's ceilings. Creepy motha' fucka's, walking on the ceiling and shit, ain't normal".
The room is dark but not as dark as the shafts due to the small light above them and the light streaming from an open vent at their feet. The room is small. Probably only 10 x 10 and is full of pipes running along the walls and ceilings. The light casts a hazy look to everything. There is another door on the other side, it looks heavier than any they have come through so far.
"We can get into a top level of the Hive from here", Johnson says, pointing his light at the vent below them. He walks over to the vent and inspects it. "Damn. It's sealed".
