A brutalist underground bunker

Generated from: A vast brutalist underground bunker corridor network seen from a third-person camera at head height, raw poured concrete walls stretching in three identical parallel hallways visible simultaneously, each hallway almost the same but one detail different in each, heavy blast doors at intervals, sodium yellow overhead strip lights casting hard shadows, identical metal doors lining each side of every corridor, a distant T-junction at the far end of each hallway suggesting the maze-like layout, oppressive and repetitive geometry Drawn in this game's art direction: Photoreal 3D rendering, high realism, heavy industrial materials including riveted steel, corroded iron, cracked concrete and rubber-sealed cabling, cinematic lighting mixing cold fluorescent blue-white with deep amber emergency warmth, strong atmospheric shadow pools and volumetric light rays through steam, shallow depth of field on mid-range camera shots, muted desaturated palette of gunmetal grey and deep teal with sparse amber and red accent lights, wet reflective surfaces throughout Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one: take a named game's look and mood, never its characters, names or logos. No text, UI, HUD, logos or editor screens inside any image.
