CUF just really doesn't feel like the right fit for me, biggest reason is that I want a damn spooky thing to feel unnatural and different from a firefight. There's a reason most horror games break down saves into different types.
Yeah... CUF is literally about how used to combat you are.
While fear in horror games should be about how good you are at facing the horrors of the unimaginable.
It's basically CUF but where the F means fear instead of fire.
If you've been up against ghouls, warewolves or aliens loads of times before, they kinda lose their shock effect.
But if you've never seen one before, I'd imagine that it doesn't matter how many firefights you've been in, you'll still shit your pants.
