科幻恐怖实验室怪物变异

High-tension sci-fi horror sequence inside a futuristic underground laboratory at night. Sterile white lighting mixed with flashing emergency reds, reflective floors, glass containment walls, computer monitors, scattered scientific equipment. Sound: low electrical hum, distant alarms, glass creaks, creature growls. Shot 1 (0–2s): Inside a laboratory corridor, a nervous security guard holding a handgun stands beside a woman in a white scientist lab coat. Behind a massive translucent containment glass wall— a huge distorted creature silhouette slowly moves. The scientist stares nervously and whispers: “I think… it’s awake.” Shot 2 (2–5s): Suddenly the containment glass violently EXPLODES inward. A massive alien creature bursts through in a shower of sparks and shattered glass. The security guard fires once but gets slammed backward onto the floor. The scientist screams and runs. Shot 3 (5–9s): The creature aggressively chases her through the laboratory. She sprints past flickering monitors and overturned equipment while the creature smashes through glass partitions behind her. Warning alarms activate. Specimen tanks shatter as it crashes through the lab. Shot 4 (9–12s): She runs into a smaller lab chamber— dead end. She backs against a counter, trapped. The creature slowly crawls toward her across the floor and walls, towering over her. It lowers its face inches from hers and opens its massive jaws wide. Shot 5 (12–15s): A loud GUNSHOT echoes. The creature jerks violently and collapses beside her. Smoke drifts through the doorway. The security guard stands there holding the handgun with shaking hands. The scientist exhales deeply in relief while red emergency lights flash across the destroyed laboratory.
