SCP-087

SCP-087 is an endless haunted staircase contained by the SCP Foundation, originating from Creepypasta-esque mythos following the Foundation, and is the main setting of two infamous video games; SCP-087 and SCP-087-B.

Description
Located in the janitor closet of an unidentified college campus, SCP-087 is hidden from the public by the SCP Foundation where Class Ds, death row inmates, are regularly sent down to explore the staircase to unwillingly gather information regarding the SCP. SCP-087 and its more famous, improved fan-remake SCP-087-B follows a Class D commanded by the experiment's director to descend down the staircase with caution while being hunted down by the entities haunting the it. In the original article, there is only one monster plaguing the stairwell; a ghostly being entirely shrouded in darkness, and only its eerie emotionless face can be seen. However, in the game, it is replaced by a trio of entities, including The Masked Man, The Red Mist Monster, and the Chesire Smile.
