Dark alien environment: a human fleeing a massive, fast creature that is constantly partially visible, closing distance aggressively, interacting violently with the environment. Wide shot: person already running at full speed, heavy impacts closing in fast behind. First reveal: a massive limb slams into the ground ahead, blocking the path at the last second. Sharp turn: runner forced to change direction instantly. Close pursuit: creature now partially visible, huge body moving with unnatural speed. Ground rupture: terrain breaks under its weight, debris flying forward. Near grab: appendage sweeps through frame, missing by inches. Sprint breakdown: runner nearly trips, barely recovering without stopping.
