Underwater Tunnel Entrance to Ocean

A first-person view emerging from a metallic door into an underwater cave maze. The door’s edges are framed by rugged rock, contrasting with its industrial design, now weathered and streaked with rust. As the view shifts outward, the dim glow of bioluminescent algae illuminates the jagged walls of the cave, casting rippling shadows that dance with the movement of the water. The narrow path ahead twists unpredictably, with sharp turns and uneven terrain. The floor is covered in a fine layer of silt, stirring slightly with the water’s current. Small marine creatures dart into crevices, adding subtle movement to the quiet scene. The atmosphere is heavy with a sense of mystery, the stillness broken only by the faint, distant sound of water dripping deeper into the maze.
