In a cinematic, high- contrast, film noir- inspired scene, reminiscent of Terry Gilliam's surreal landscapes, Gordon Freeman, a bespectacled, bearded Caucasian man with a rugged expression, stands defiantly in his worn, green and yellow HEV suit, adorned with a glowing Lambda emblem on his chest, amidst the eerie, bioluminescent world of Xen. Soft, diffused light from an unseen, high- key source casts long shadows, while warm, golden hues of ambient, practical lighting from glowing, ethereal flora and fauna dance across his suit. With a firm grip on his trusty, large red crowbar, Gordon engages in an intense battle with a massive, tentacled creature, its appendages snaking around him. The atmosphere is tense, with a shallow depth of field, and subtle film grain, evoking a sense of grit and realism, while the color grading emphasizes muted, earthy tones, punctuated by bursts of vibrant, otherworldly colors
