About 1shotadventures

This blog is a collection of free roleplaying adventures — and the design thinking behind them. I like lots of different roleplaying systems, but here you’ll mostly find material for Dungeons & Dragons, Call of Cthulhu, GURPS, and Broken Compass.

Because every game group needs a break from their usual roleplaying setting, you’ll find many of the adventures on this blog use genres that aren’t typical, such as historical horror, pulp adventures, Arabian Nights, steampunk, 1960s spies, and lots more.

My goal is always to give the GM all the stuff they need to run a “professional grade” adventure with their friends with as little effort as possible. This means my adventures usually include not just the adventure itself, but also cool handouts, pregenerated characters, and virtual tabletop assets (VTT) for GMs running their games online. Prepping great adventures and GM’ing is time intensive, so hopefully this site helps!

If you’re looking to get started, you can find a complete list of the adventures in the Adventure Index.

If you like any of these free adventures, all I ask is that you post a comment here and let me know how it went. Find me on Threads @thalcos or Bluesky at @1shotjc.bsky.social

Also, check out my YouTube channel for more tips, reviews, and overviews of these adventures. Enjoy!
