What’s your perfect mod collection for playing L4D2?

I wanted to replay L4D2 from start to finish, and I’m curious to know which mods or collections fans usually play with on a daily basis.

If you know of any that mix Nightmare with good graphics, let me know. My main idea was to create more of a Survival Horror feel dark atmosphere, upgraded visuals, and every bullet counting. But honestly, any solid collection works for me to try out.

Big hug!
