Train Zombie Apocalypse — 15s Survival

0–1.2s: A nearly empty train carriage races through a dark tunnel. Flickering fluorescent lights reveal blood smeared across the windows. A terrified passenger hides beneath a seat while distant screams echo through the train.

1.2–2.4s: A young man cautiously crawls out from hiding, clutching a broken metal pole. He looks through the carriage and sees several infected passengers standing completely motionless at the far end.

2.4–3.6s: One infected suddenly jerks its head toward him. Its mouth opens unnaturally wide as it releases a guttural scream. The others instantly begin moving.

3.6–4.8s: The man sprints through the carriage. Infected passengers chase him between the seats, violently knocking luggage and chairs aside. Handheld camera shakes intensely.

4.8–6s: He reaches the connecting door and struggles with the jammed handle. An infected crashes into the glass behind him, cracking it.

6–7.2s: He finally forces the door open and escapes into the next carriage. Several infected stumble through after him as the train violently rocks.

7.2–8.5s: A woman hiding behind a luggage rack suddenly grabs his arm and pulls him down. They hide beneath the seats while infected search the carriage above them.

8.5–10s: An infected slowly crouches beside the seats, almost discovering them. Its bloodshot eyes scan the darkness while the survivors hold their breath.

10–12.5s: The train abruptly enters a brightly lit station. The infected freeze for a moment, confused by the sudden light. The survivors notice the platform outside is completely abandoned.

12.5–15.5s: The train doors unexpectedly open. Survivors rush onto the platform, but a massive crowd of infected suddenly emerges from another stopped train across the station.

15.5–18.5s: Panic erupts. Survivors run along the platform as infected pour through the station entrances from multiple directions. Emergency alarms flash and echo through the underground station.

18.5–21.5s: One survivor spots an emergency staircase and leads the others toward it. An infected grabs a survivor's backpack, ripping it away as they escape.

21.5–24.5s: They reach the staircase, but the metal security gate begins closing automatically. Survivors desperately squeeze underneath while infected slam into the gate behind them.

24.5–27.5s: The survivors climb upward into a deserted station lobby. Suddenly, every television screen flickers on simultaneously, displaying an emergency warning about an unknown infection spreading across the city.

27.5–30s: The survivors stare at the screens in horror. Behind them, the station doors slowly begin opening by themselves. Dozens of infected silhouettes appear outside as the emergency announcement cuts into static. CUT TO BLACK.
