The Big Squirm

A well-to-do neighbourhood, each building dangling by chains from the Downgate Arches. The resident factions traded in Scarf-Worm futures—until the bubble inexplicably burst. That's where you come in.  

The Big Squirm is a hardboiled detective RPG adventure for TROIKA!, the science-fantasy RPG. Players take the role of private investigators working for one of several factions embroiled in the mystery of the missing Scarf-Worms. Players will search, steal, and trade for clues, exploring a wealthy neighbourhood in the city of Troika. What they uncover will have massive implications for your ongoing campaign, and provide a huge amount of gameable material to take your games even further. The clear goals and open-ended creativity of The Big Squirm is also the perfect way to introduce new players into the world of TROIKA!, and TROIKA! is a great introduction to the world of roleplaying.
