How to play The Horror of H.H. Holmes on Mac

Game summary

The Horror of H.H.Holmes is a survival game where you enter his "Castle" to search for evidence, while evading Holmes. The game strives for accuracy. Holmes was one of America’s first serial killers in the late 1800’s, and built a hotel dubbed the “Castle”, which was a labyrinth of secret passages, dead ends, stairs leading nowhere, and inescapable rooms, where he killed several people for various reasons. Using blueprints and diagrams, along with witness testimony, these give a good estimation of what it was like to explore the structure. The game will allow users to do that by itself, or play a deadly game of hide and seek, where the player has to collect evidence against Holmes, while Holmes is attempting to find the player and put an end to his latest “problem”. There are two parts to The Horror of H.H. Holmes, one is the game, and the other is simply a virtual walk through of the Castle, where you can take your time and just wander about. Both ways can be viewed in Virtual Reality, or standard viewing. Support for the Oculus Rift/HTC Vive headsets is planned. The interior of the Castle is being painstakingly recreated from blueprints, diagrams, newspaper drawings and eyewitness accounts. While it can never be 100% accurate, we believe we can get a pretty good feel for what the interior was like.

Play The Horror of H.H. Holmes on Mac with Parallels (virtualized)

The easiest way to play The Horror of H.H. Holmes on a Mac is through Parallels, which allows you to virtualize a Windows machine on Macs. The setup is very easy and it works for Apple Silicon Macs as well as for older Intel-based Macs.

Our favorite feature of Parallels Desktop is that when you turn off your virtual machine, all the unused disk space gets returned to your main OS, thus minimizing resource waste (which used to be a problem with virtualization).
