See Version 5.2.
- This version is only playable up until the basement. Upon entering the basement, the screen will turn black and Hiroshi will tell the player that he/she will have to finish this in Version 5.2.
- The Mansion design only has slight changes done in some rooms compared to Version 5.2. One example being the archive room having shelves that extend to the wall.
- It's largerly identical to version 5.2, to point of it being arguably redundant to refer to it as a separate version.
