The custom difficulty level is a mutation. You need to look there.

hello,How can I access the difficulty mod in l4d2? I'm looking here and I can't access the respective mod. Which tab should I go to? And in the difficulties, why does only the expert level appear and nothing else?

And I see that I'm not the only green one

Hi, I can't comment on your workshop thread so I'll ask here instead. When I try to play on nightmare difficulty, the mutation changes which chapters are available. For example, when I try to do nightmare dead center, the only 2 options are gun shop (ch2) and atrium (ch5). it almost seems like it's survival rather than campaign.

our old channel youtube did the favor of giving a strike, but we are re-recording all our videos, follow the link of our channel

hey man, how are you? I sent you an invite, I wanted to ask you a favor, you who already understand how to create mutations is very simple.

I particularly like your mutations a lot and I have some videos recorded with the restart duo on my channel.

but looking for a challenge that my group does I wanted to see with you if you can do the nightmare realism mode in the hard eight mutations and special delivery
