One of the main reasons In Sound Mind was such a pleasant surprise to me a few years ago was because I heard it was from the team who made Nightmare House. In my memory, Nightmare House was a very annoying jump scare Half-Life 2 mod that was of the same obnoxious horror design mentality as something like Cry of Fear. But then, I saw a lot of people speak of that mod with genuine admiration and it popped up in different conversations described as one of the best single-player Source mods of all time… As I’ve come to learn, what I was thinking is the original Nightmare House, while what people love is Nightmare House 2.
Which is where Nightmare House: The Original Mod comes in to clear things up a bit. Released as a free game on Steam, partially to promote the development of a complete remake of this mod, this game combines both of the original Nightmare House mods into one experience. With the original mod serving as a “Prologue” and the praised Nightmare House 2 taking up the most of your playtime. As far as I’m aware, apart from many quality of life tweaks allowed by a standalone release, both mods are presented almost exactly as is with only minor changes.
