I saw this movie when I was little and I never quite knew the name of it. I knew that it had survivor in the tile. This is the first website that actually had the movie listed. Pretty scary stuff as I remember it. The bats were pretty ferocious and I don't recall anyone making it. From the plot summary, I guess they did??? I would love to see it again though. I was even beginning to think that I never this movie never existed and I was confusing it with Aliens. This movie came out when special effects were not so prevalent and a lot of the horror was more mental than visual. I place this movie up there with "Gargoyles", and "Don't be afraid of the Dark". Those movies kept me up at night for weeks!!!
