Sub-Base Underground Arena

Generated from: Top-down aerial view of an underground submarine base arena, two parallel long concrete corridors running north to south flanking a central open dry dock chamber with a shallow pit, metal blast doors at each end as entry points, exposed pipe clusters along walls acting as cover, flickering cold blue-white fluorescent lighting casting grid shadows on wet concrete floors, dark water drainage channels cutting across the central area, symmetrical layout with clear sight lines through the corridors Drawn in this game's art direction: Photoreal stylised 3D rendering, high detail surface materials including worn concrete, matte metal and scuffed plastic, sharp hard-shadow directional lighting with strong contrast, desaturated military palette of charcoal grey, dark navy, olive and amber accents, cinematic slight vignette, grounded gritty realism matching a competitive military FPS mood 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.
