GUMSHOE

GUMSHOE is a system for designing and playing investigative roleplaying games and adventures, emulating stories where investigators uncover a series of clues, and interpret them to solve a mystery.

In a GUMSHOE game, the player characters discover something which triggers their investigation, and then the Game Moderator (GM) narrates them through a number of scenes, during which they use their Investigative Abilities to gather the core clues they need to move the narrative forward. They must then put the clues together to uncover the secrets behind the mystery.

    Any RPG which uses the GUMSHOE system redefines it for that setting, and so there is no “GUMSHOE book”. Each of the RPGs below contains the full GUMSHOE rules for creating characters and playing in that world, as well as guidance on designing your own investigations for that particular setting.

    GUMSHOE is the groundbreaking investigative roleplaying system by Robin D. Laws that shifts the focus of play away from finding clues (or worse, not finding them), and toward interpreting clues, solving mysteries and moving the action forward. GUMSHOE powers many Pelgrane Press games, including The Yellow King Roleplaying Game, Trail of Cthulhu, Night’s Black Agents, Esoterrorists, Ashen Stars, and Mutant City Blues.

    We usually do our perennial GUMSHOE panel, the Investigative Roleplaying Masterclass, at conventions ranging from Gen Con to Dragonmeet to the Kraken. With the convention circuit suspended indefinitely, we thought it was time to do a virtual version of it, as part of our lockdown-inspired ramp-up of our YouTube channel. The live stream has now been archived to view at your leisure. It starts with Ken arriving fashionably late in order to preserve the in-person convention feel:

    You’ll note that we retitled it a bit to be search-friendly for the broader YouTube audience. And yes, that includes the dreaded space between “table” and “top” in “table top roleplaying” because that’s how the kids search for it these days.

    The GUMSHOE Community program is now even bigger!

    Earlier this year we launched the GUMSHOE Community program, making Ashen Stars content available to creators. We have now expanded the content available, and so the program now includes the following game lines:

    If you’re not familiar with the Community Content concept, it means we’ve made some elements of these GUMSHOE games (e.g. some IP elements, art, and layout assets) open for members of the community (that is, you!) to write and publish your own GUMSHOE content on DriveThruRPG.

    We’ve got a number of great Ashen Stars PDFs already available, to show you what’s possible. These include:
