Trail of Cthulhu is an award-winning standalone game produced under license from Chaosium, set in the 1930s, now in its third print run, and produced in five languages. Trail of Cthulhu uses the GUMSHOE system, which is finely tuned for investigative play – the challenge is in interpreting clues not finding them.
It supports both Pulp (for Indiana Jones, Robert E. Howard, thrilling locations sorts of games) and Purist styles of play (for intellectual horror and cosmic dread). HP Lovecraft’s work combined both, sometimes in the same story.
It includes a new take on the creatures, cults and gods of the Lovecraft’s literature, and addresses their use in gaming. It adds new player backgrounds, and bulk out the GUMSHOE system to give intensive support for sanity, incorporating into the rule set the PCs desire to explore at the risk of going mad.
Trail of Cthulhu won two Ennie awards for Best Rules and Best Writing, as well as receiving an honourable mention for Product of the Year.
Trail of Cthulhu is a very well supported game, with award-winning supplements by Ken Hite, Robin Laws, Jason Morningstar, Adam Gauntlett, Graham Walmsley, Gareth Hanrahan and Bill White.
