This is the repository of house rules and information for Call of Cthulhu and Delta Green. I have the PDF’s for 7th Edition of Call of Cthulhu and the pre-release for coming Delta Green stand-alone RPG so I’ll be formatting things in those terms – not that there is any significant difference from the 1st Edition of Call of Cthulhu…
I will be using the “Unnatural” skill title from Delta Green instead of “Cthulhu Mythos” skill title from Call of Cthulhu because I like the vagueness. It doesn’t imply that everything revolves around Cthulhu and it’s ilk, but the two skills are otherwise identical in effect. It’s worth noting that some of this may significantly impacted by the publication of Pulp Cthulhu.
