Cultists of Cthulhu is a cooperative-but-with-a-traitor boardgame set in H.P. Lovecraft's Miskatonic University. It's my second game, and is doing quite well on kickstarter, and with only one day left before the campaign ends, has reached all of its stretch goals, so there's never been a better time to back!
It is a dark and stormy night. A lightning bolt has shattered the Elder Sign over the entrance to Miskatonic University's library, leaving open the path for unspeakable eldritch horrors to encroach upon our world. Are you an Academic, investigating these strange happenings and trying to preserve your school, yourself, and your sanity? Or are you the Cultist, secretly plotting the downfall of your so-called "friends"?
Cultists of Cthulhu is on Kickstarter for one more day, and it's reached all of its stretch goals, so there's never been a better time to back. I don't have wifi at home right now and I'm in a library that closes in 8 minutes, so I can't possibly write up as good of a case for it here as on the kickstarter page, so just click on the dang link. It's really good. But don't take my word for it, check out these reviews by Undead Viking and Let's Level Up. Also, it was endorsed by Sandy Petersen of Cthulhu Wars and the Call of Cthulhu RPG fame, so you know it's gonna be good.
