One of the great things about Call of Cthulhu is that the rules remained largely unchanged until 7th edition.

Call of Cthulhu Classic 2" Deluxe Boxed Set ($60 PDF)

This is from the 2E boxed set reprint Kickstarter. 2E rules plus a year's gaming of adventures.

Shadows of Yog Sothoth - campaign
The Asylum & Other Tales - seven adventures
Cthulhu Companion - four adventures + splat material
Trail of the Tsathogghua - three adventure mini-campaign
Fragments of Fear - one scenario + splat material

Masks of Nyarlathotep ($17.50 PDF)

This is a one-book version of one of the best campaigns ever published for CoC.

Beyond the Mountains of Madness ($20 PDF)

If you love HP Lovecraft's At the Mountains of Madness then this is the campaign for you. I ran it, with the optional sourcebook material (which is mostly lots of extra handouts and details about an Antarctic exploration), and inserted more adventures as the PCs traveled from New York to Australia before the final leg to Antarctica. Definitely can be a slog that way but mostly it worked well I think.

Call of Cthulhu supplements range over multiple eras and locations. I think the above is the default 1930's and either North-Eastern USA or globe-hopping.


If you want to play with 7th edition it's more constrained.

CoC Keeper Rulebook ($28 PDF)
CoC Investigator Handbook ($23 PDF)

There is also a starter set (which uses the quick start rules) though I hesitate to recommend cut down rules that can give you a good but limited experience. With the 7E version of Masks at $60 we fall ball to-- never mind. I was going to recommend Horror on the Orient Express at $40 but actually the split up the campaign into two volumes and I assume v2 will also be $40.

A Time to Harvest ($26) - a six adventure campaign set in 1930's Vermont
Doors to Darkness ($17.50) - five adventures for beginner keepers, set in 1920's New England.
The Shadow Over Providence ($4) - an adventure set in 1928 Providence, Rhode Island.
