Upon entering Room 810, the player will find a two-story Victorian-styled mansion, Specimen 12 itself. According to the notes scattered about, there is a commotion going on below the kitchen. There are also hints of what seems to be a man chasing after the note writer.

The mansion consists of a wine cellar, a parlor, a dinning hall with a fireplace, two hallways, a library, and two bedrooms, all of which can be explored by the player. Once the player hears The Old Man (possessed by Specimen 12), they must hide using the local objects, otherwise he will quickly sprint towards the player, instantly killing them. They must eventually find the key to the underground room, where the exit room key can be found. After escaping the room that you get the key from, The Possessed One continues to chase the player like the other specimens.


  • There is a very rare chance that a hanging corpse will appear for a split second above the dining hall door at the entrance. It has not been added back in HD Renovation, however.
  • The Old Man will not quickly sprint towards the player in the HD Renovation, instead slowly walking up to them, giving them more time to hide and avoid instant death.
