Sci-Fi Horror is a sub-genre of both Science Fiction and Horror that uses scientific advances or futuristic settings as a source of fear. Notably, the first Sci-Fi genre work note was also one of the first works in this sub-genre: Mary Shelley 's Frankenstein, published in 1818.

While many sci-fi movies contain heavy doses of fear-inducing elements, a few verge on horror without completely giving in to jumpscares. The sci-fi genre frequently intersects with horror, particularly in stories that revolve around world-ending calamities that destroy humanity (and all our creations and discoveries).
