SCP-087-B is a map in Slender Fortress.
Somehow, the RED team has been employed into the SCP Foundation where they are tasked with filming their exploration of SCP-087, an endless flight of haunted stairs. After picking up the camera by meleeing it, as instructed by a doctor via a radio, the team must travel through 15 flights of stairs plagued with The Sisters. Several traps are littered through the area, including a fatal dead-end and a few events involving monsters from the actual SCP-087-B game. Some paths include a two-way paths that can lead you to death and a path that connects to the escape route.
The BLU team is the hallways of a Foundation site, and the PVP arena is a storage chamber.
