Hall of Infinite Doors

You light a flare and wave it in the darkness. The flash of it combined with the nightvision blinds Sokolov. As he lies on the ground screaming in agonym you reach and turn the lights back on, thus adding to his screaming. You decide to leave him there on the floor, hes harmless now. You walk through the next hallway, with Sokolov wailing like a banshee then the lights go off again in the Right Disposal Factory. Sokolov's screaming ends immediately with the sound of something being torn open. Whatever knocked you out in the left disposal facility is back. You quickly run to the end of the hallway and shut the door behind you. Your radio beeps.
