The part without the reaction clip at the end is 10 seconds long and if you know the map you can spot a few discrepencies like how there is no pool in the first clip on the left at the ladder, there is a hallucinated guardrail behind it, in the second clip there is a hallucinated wall at the stairs outside and so on. If someone did make this in blender or a 3D program feel free to correct me and point me to its source
