Underground cave tunnel network

Generated from: Top-down angled overview of a cave tunnel network arena, rough dark basalt rock floor with narrow branching corridors connecting larger open cavern chambers, stalactites visible from above, bioluminescent blue fungus patches providing dim ambient light, zombie spawn points at all tunnel entrances in the outer ring, a central cavern chamber as the main fight area with scattered boulders as cover, pools of dark water blocking certain paths, flickering torches on cave walls, photorealistic textures Drawn in this game's art direction: Photoreal cinematic 3D rendering, high-detail realistic textures, worn and gritty materials, dramatic chiaroscuro lighting with practical light sources such as fire muzzle flash and emergency lamps, desaturated cool grey-green base palette with warm orange and red accent light, handheld camera feel with slight depth of field, Left 4 Dead dark survival mood without its characters or logos 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.
