A Quiet Place VS The SCP Foundation
Let’s assume that the alien invasion of the Death Angels happens to take place in the SCP universe. We’ll also assume that the asteroid somehow slips past Foundation security measures and manages to break apart in Earth’s atmosphere just like in the movies. From what we know of the films there were around 123 confirmed impacts, on land anyways. There seemed to be roughly a few hundred Death Angels per meteor, though the larger ones likely had thousands.
We’ll assume their total number is a little over a hundred thousand, with these impacts happening worldwide. Some directly in major metropolitan areas, while others land in the desert or countryside. In the movies the world’s governments and militaries failed spectacularly to contain the threat, but the Foundation has dealt with extraterrestrial forces many times before.
How long would it take to contain the situation and how difficult would it be considering the Foundation’s immense resources? This is including both the esoteric and thaumaturic ones assuming those would likely be deployed since this would PROBABLY be an XK-Class scenario of some kind.
