SCP-087 comes from the SCP Foundation, a collaborative horror-writing project built around fictional paranormal objects, where SCP-087 describes an endless, dark stairwell. A fan-made horror game, SCP-087-B, turned that setting into a first-person descent, and its sudden face jumpscare became one of the early YouTube horror gaming moments, shared in Let's Plays, reaction videos and soundboards. The clip endures because the stairwell premise is simple and unsettling, and the scare needs no context to work in short horror edits, memes and Halloween videos.
