I’ve been running a weekly Call of Cthulhu game wherein each session is a self-contained investigation. A few weeks ago, I had 2 new players in the session who had played DnD before, but never CoC. The immediate difference is that CoC decides to take the track that bullets are very deadly and people take a while to heal from injuries.
Typical gun damage? 1d10.
Typical Investigator health? 8-12 HP.
How fast can you heal? Depending on the GM, anywhere from 1 HP per day to 1 HP per week. It also features a sanity score, so what doesn’t kill might make you crazy.
The session took place (as CoC tends to do) in the 1920s era. At one point the players ended investigating a mansion while looking for its missing owner.
During this investigation, at one point—very suddenly—fungal-like tentacles oozed out of the cracks and the floor and started enveloping one of the investigators. Everyone panicked and attempted to free him, but other pseudopods attacked, hampering any effective effort lest they too get snatched up.
After a few minutes, the fungal pseudopods pulled the unlucky investigator through the floor. The other players hurriedly ran to the basement door and started bashing it down.
They succeeded… only to find that the whole basement is filled with an amoeba, fungus-type thing/abomination.
At the point I realized I had forgotten to ask one of the other players what his investigator was going to do (while the others were bashing down the door.)
He said “I get the hell out of that house and run to the car!”
One of the players responded, “You’re just going to leave your friend to die?!”
To which he replied with the best quote I’ve heard describing the deadliness of the system:
“YOU DO NOT UNDERSTAND HOW THIS GAME WORKS!”
