This mod turns Fallout 4 into horror
Piligrim is a mod for Fallout 4, making a pretty live setting game in something more like Silent Hill.
This mod does not bring into the game a lot of new content, so do not wait for eerie quests to investigate a terrible house or save a psychopath with a saw. Piligrim aims to change the weather, sounds and lighting environment to create a completely different atmosphere of gloomy inevitability.
The dynamic music system varies depending on the weather, and also includes a completely new soundtrack, suitable for visual style.
