What's changed from the First Edition?
Well, the 2e is full colour, for one thing. Glorious chapter images come courtesy of Paul Tomes.
The bigger page count means more guidance and thoughts on running a campaign – where individual connections survive, even if individuals do not. More magic, plus books of lore. And an expanded intro adventure, Save Innsmouth – with variations, discoveries, strange plots, and horrible revelations.
2e presents Mythos creatures in greater detail, expanding on their origin and purpose. Cthulhu Hack 2e is about throwing off the shackles of preconception, giving the Mythos the opportunity to breathe. Random tables change up their motivations, purpose and physical appearance - and the book has a scattering of other tables and hooks to help you kickstart a new investigation.
Oh, and we lost the "The" in the title.
