On November 2nd, 1936, the world died. Finally, the stars had come right; and things that lurked under the seas for eons rose to claim their rightful place. Now, they rule the earth, stalking it like titans. Millions of women and men died - yet you survived, doomed to wander the ruins, searching for answers. What went wrong? Are there others like you? How can you stay alive? And is there a way to put this right?
Cthulhu Apocalypse is a survival horror supplement for the Trail of Cthulhu roleplaying game that takes Investigators into a terrifying post-apocalyptic world.
Using the award-winning Apocalypse Machine, GMs can destroy the world any number of ways - including the death rays of alien tripods, a plague of white flowers, or the rising of Great Old Ones - and run adventures of investigation and survival in a land transformed beyond recognition.
