i have the physical and pdf version, so i will be referencing the physical book.

this is a soucrebook, this book allows you to be able to essentially punch cthluhu in the face. which you know, it's fun!

the setting is in the 1930s or whatever setting your campaign is in, and a few key features in this book:

1) Hero Archetypes, this are specific abilities to your character, think class stat benefits from dnd and you're on the right track. you get additional 100 points for skills and additional talents and traits. 2) increased HP. Base CoC your health isn't very high, at most it can be 12-15hp lowest 7-9hp. in pulp, the hp is double digits so when building your character, it is encouraged to get higher stats. 3) this is more action oreinted, sure you can definitely role play, it's still the foundation of CoC, combat you have a much better chance of walking away, and Luck plays a much bigger role in pulp cthulhu.

if you want an Indiana Jones, or 1990s The Mummy like adventures, this is a fun game.

Reallhy useful and updaded when needed. This gives you the ability for Investigators to be heroic and able to fight back in the tradition of "The Shadow", "Doc Savage" or "Brenda Starr".
