I ' m on PS 4 , put in a rag doll physics mod that I love . When you hit an enemy they don ' t just stand their like a brick wall , they fall over and attempt to get back up . It works both ways , so running out in a firefight is damn near impossible you get hit , you get knocked down , and if there are multiple enemies within striking distance they ' ll keep you down until you ' re dead . Really changed my play style , very suspenseful and at times EXTREMELY FRUSTRATING , but I ' m of the opinion that surviving in the wasteland should be a struggle . Other immersion mods 1 Remove cash register sound effect when enemies are killed . 2 Remove HUD in game settings seriously next level gaming 3 Any mod that increases enemy awareness and search area
