Horror+ is a Minecraft horror modpack for versions 1.19.2 and 1.20.1, designed to be difficult. The author's only advice: build your house underground. Both versions include From The Fog, The Man From The Fog, and Whispering Spirits.
With VR support through Vivecraft, you can also play using a VR headset. The pack includes AmbientSounds, Sound Physics Remastered, and the Spooklementary shader. You can add more mods, resource packs, and shaders; server owners should check the required server-side mod list for their chosen version.
