Is there a guide for us to add our own horror's to this? I saw an option to add mods so I'm curious.

It won't necessarily teach you how to make your own horrors, but someone has compiled every mod players have made so far, along with quick instructions on where to put them. From there, when you visit "mods" in the main menu, the game should autodetect everything you included in your "custom" folder. Hope this helps! :)

hey Quto, right now people are using a mod to make mods as explained in this video I created. To add them you need to place them in a specific folder as jennatar explains. I have a screenshot too
