SCP-303 - The Doorman

SCP-303 is a creature hiding behind a small fire door with a rectangular window. When players approach SCP-303 their sanity drops dramatically and they become very frightened. Player breathing will become heavier, whimpering can be heard, and sanity will continue to drop. Players will always be too terrified to open the door, however. Players who get close enough to the door will hear a wheezing sound and their vision will be reduced dramatically. It is unknown if SCP-303 is harmful at this time.
