Female Space Marine In Toxic Industrial Tunnel

A female space marine in detailed sci-fi armor, holding a rifle, stands in waist-deep glowing toxic green water in a dark, flooded industrial tunnel. The tunnel is filled with pipes, valves, and machinery, with a raised walkway to her left. Grimy green light emanates from overhead fixtures, casting eerie reflections on the water and pipes. The atmosphere is dark, mysterious, and dangerous, with steam or mist rising from the water. Comic book art style, with visible brushstrokes and bold black outlines. Strong contrast between the glowing green and deep shadows.
