Facility Room and Corridor Background

Generated from: Cinematic photorealistic dark sci-fi horror scene: an abandoned underground research facility starting room and corridor. Cold blue-green industrial metal walls with rivets, condensation, flickering dim panel lights. Deep atmospheric shadows, volumetric fog creeping along the floor. Emergency red accent lights at distant intervals. Heavy steel door at the far end of a corridor, half-open. Concrete floor with dark stains. Faded insignia on wall reading "FACILITY 7". Subtle film grain and analog CCTV noise overlay. Non-cartoon, realistic dark render. Portrait 9:16 mobile composition, key focal point centered, no text overlays, no characters visible.
