A crowded apartment party is in full chaos when a massive BOOM shakes the floor. Drinks spill. Everyone freezes. Another explosion erupts from the apartment below — screams echo upward. Then another. Something huge is smashing vertically through the building floor by floor toward them. Panic erupts. Everyone sprints upstairs as entire sections of flooring explode upward behind them. Just as people reach the stairwell, a gigantic alien creature bursts through the floor and snatches two people mid-run. ⸻ Shot 1 (0s–2s) Inside loud apartment party. Music blasting. Suddenly the FLOOR EXPLODES upward beneath a dancing guy, launching him sideways as concrete and dust blast everywhere. People scream instantly. LOUD monstrous roar from below. ⸻ Shot 2 (2s–5s) Another violent BOOM from the apartment beneath. The floor caves inward. People start stampeding toward the staircase. Below them: another floor explodes upward through the hole like something gigantic is punching vertically through the building. ⸻ Shot 3 (5s–8s) Handheld panic. Everyone sprinting upstairs. Floor sections behind them keep ERUPTING upward one after another in sequence like a shockwave chasing them. Walls crack. Lights flicker. Someone falls through a collapsing step. ⸻ Shot 4 (8s–11s) The staircase shakes violently. A woman turns back — A massive alien limb punches through the stairwell wall behind the crowd. Concrete rains down. The creature’s glowing eyes become visible through dust as it forces itself upward. ⸻ Shot 5 (11s–15s) — PAYOFF People reach the next landing thinking they escaped. Suddenly the ENTIRE FLOOR beneath two runners detonates upward. The creature bursts fully through the floor in a shower of debris and grabs them mid-air. The remaining survivors keep running upward screaming while below them the alien continues smashing vertically through the building toward camera.
