Call of Cthulhu 7th Edition is coming out in the middle of April.
The Keeper Rulebook and Investigator book are the “Core” 7th Edition books. (You don’t need the Investigator book to play, but it’s a good supplement).
All the old 6th Edition Adventure books are compatible with 7th Edition with just a little tweaking.
Alongside the launch of 7th Edition Chaosium is introducing their first Organized Play campaign called The Cult of Chaos! Just Games will be offering full support for the Cult of Chaos adventures, so come on out to Cthuesday (Tuesday) at 6 pm and play some Call of Cthulhu!
