Hollow Ground

You already know that its a horror pack. It includes many different creatures/dwellers that will stalk and kill you, some pretty nice shaders to set the tone. Also it includes different abandoned structures to offer some "protection" against these vile creatures. Some other parts include guns, and even a backrooms like feel once you find the slit that missing. Also there are some world building tool to make the terrain much smoother and rivers seem more personable. There are a couple of QOL mods to make sure the person doesnt hate their life too much. Also some nice building mods to make sure if people want to make a nice house they are able to do so easily. Audio mods make it more immersive along with some changes to the persons model and healing style to make the gameplay feel more immersive. There is ragdolling but you can be dragged by your friends if necessary. Origins offers a helpfuls start to the early progression that is quite necessary for a mod like this. Good luck and have fun!
