Continuous linear 3D environment terrain, transitioning from an abandoned mountain road into a claustrophobic underground utility tunnel. Liminal space horror aesthetic.

Layout & Geometry:

Start Area: 50-meter curved, weathered asphalt road. Cracked surface. Flanked by broken metal guardrails and steep, rocky terrain on one side, a sheer drop on the other.

Transition: A brutalist concrete archway embedded into a cliff face, serving as the tunnel entrance. Heavy, rusted industrial double doors, forced open.

Main Pathway: A 200-meter long, straight, narrow concrete utility corridor. Rectangular cross-section.

Ceiling & Floor: Ceiling features continuous linear exposed pipes and wire trays. Floor includes shallow water drainage channels along the baseboards.

Technical Details: Modular architectural shell, seamless structural geometry. Low-to-medium polygon count.
Textures: Gritty PBR materials. Wet, damp concrete, rusted metal, and degrade

Long underground pedestrian tunnel, straight and symmetrical. White ceramic tiled walls with visible grout, slightly dirty and aged. Low white ceiling. Warm fluorescent wall lights placed evenly on both sides, soft yellow glow. Concrete floor with greenish-brown damp stains and a single circular manhole cover in the center. Strong centered perspective with a cool blue daylight exit visible at the far end. Empty, silent, unsettling liminal atmosphere. Realistic scale, human-sized, game-ready 3D environment, optimized geometry, subtle horror mood.

A small, abandoned underground sewer corridor with circular concrete walls. The place looks old, dirty, and damp, with cracks, moss, and stains on the concrete. At the very beginning there is a solid wall with a doorway hole in the middle, as if a door had been broken and removed, leaving rough edges and debris around the opening. The corridor then continues and turns sharply to the right. At the right turn, the corridor ends with another wall. In this wall there is an intact old heavy metal door, rusty and closed, giving the feeling that the path is blocked. The whole interior should feel dark, creepy, and abandoned, like a forgotten sewer passage.
