In Cthulhu: Death May Die, inspired by the writings of H.P. Lovecraft, you and your fellow players represent investigators in the 1920s who instead of trying to stop the coming of Elder Gods, want to summon those otherworldly beings so that you can put a stop to them permanently.
Cthulhu: Death May Die puts players in charge of Investigators looking to defeat an Elder God that is being summoned to Earth. They are running late, as the summoning ritual is already underway. But if they can collect enough clues to find a weakness, or alter the ritual just enough to cause one, they can blast the god to death before it gets a foothold. Working together, players will fight cultists, search for answers, and try to keep their already-broken minds from warping even further.
