SOS – The Last Voyage of the Hope
Call of Cthulhu Scenario by Miskatonic Repository / Chaosium
When hope becomes the last weapon…
A luxurious steamship.
A mysterious voyage.
And a ritual that takes you to a place where nothing you believe to know still applies.
The “Hope” does not vanish in the storm.
It is devoured.
What follows is not a struggle for survival against the sea –
but against the incomprehensible.
A horror adventure beyond reality
In this dark, densely atmospheric scenario, players become part of a nightmarish transition
into a foreign dimension.
A place where reality shatters, time stands still, and something ancient pulses in the
background.
To escape, they must:
Find and redeem lost souls
Traverse disturbing parallel worlds
Make moral decisions
Resist the influence of the Great Old Ones
But even if they succeed…
a return is not guaranteed.
