The scene is set in a dark, claustrophobic underground military bunker, with long, narrow metal hallways, dimly lit by flickering overhead fluorescent lights. The constant rain leaks through cracks in the ceiling, creating a rhythmic drip as it hits the cold concrete floors. The camera, positioned in the player’s perspective, keeps a tight focus on the sleek, futuristic assault rifle as the player engages with enemies emerging from hidden corners. The environment is sterile and cold, with metallic surfaces and old machinery, while the distant rumble of explosions shakes the entire structure. Enemies, clad in tactical gear, patrol the corridors, utilizing cover behind broken equipment and barricades. Muzzle flashes and ricocheting bullets illuminate the tight space, while sparks fly from damaged electronics, creating brief flashes of light. The rain outside creates a muffled roar, barely heard through the reinforced concrete walls. The atmosphere is tense and immersive, with every step echoing in the empty, labyrinthine corridors.
