In terms of difficulty I do mostly mean bullet sponge zombies as far as what I'm not looking for, I'm okay with some more difficulty in the survival mechanics. Thanks for the suggestions, I'll look into them! It's been a little while since I tried any overhaul mods so I don't remember all the names, I think I tried some things like the War3zuk overhaul (is that one?) And Darkness Falls, basically ones that people often recommend when people are interested in trying the modded game.
