The corredor is dark with malfuntioning, flickering lights. The floor is a raised grating with pulsating blue and red lights below your feet. At the end of the corredor is a glowing power generator (which appears to be struggling) and an open door. The sign says "Warning! Dont open door if sign is flashing!" But the sign is flashing, and the door has been broken open with a bloody hand print on the plexiglass pane. You enter the forbidden area, which is encased in black plastic walls and ceiling.
