Horrifing mod - Left 4 dead 2 Nightmare

So I have been seeing so much nightmare mods, The last video I have done it was just atmosphere and I wanted to change some things like weapons scripts, AI on special infected and it truly turned horrifying. These AI's play more smarter and While recording I tried doing another map before going with swap fever, This mod really changed the way Left 4 Dead 2 feels and really made it more horrifying. I hope you enjoyed Please share it around and leave a like, it would help me grow!
