I was actually tempted to make a horror CS mod once; I even started it. I just never really continued it.
I did some stuff a few days ago and managed to do something with <ANP, although I did decide to stop continueing what I made(which would be a part of the horror mod) before it gets too dark and stuff.
It was more or less that I didn't really know how to use the <ANP command, but it actually is more simple than I expected.
