SCP-087-B is a small horror game, similar to the chilling SCP-087, which finds you trapped with no way to go but down into the darkness.
You begin by waking up in a strange place, just like in Slenderand indeed SCP-087. Unlike Slender, you're indoors, and have to make your way through claustrophobic corridors and stairways. There are noises, and something is definitely there, but what is it? Do you have what it takes to carry on going down through the darkness?
