Haunted Hallways is a custom story for Amnesia loosely based on SCP 087 B. But this custom story differs a bit from SCP 087 B. Your goal is to survive whenever and wherever possible. Death is not an option. Survival... Harder than it sounds like. Could you survive for more than an hour in this building? Impossible. Not with the paranormal forces.
It's up to you to figure out where did you go.
