Boundless RPG (PDF)

Boundless is the ready-to-hack, old school style dungeon crawl RPG of perilous journeys and desperate delves. It is free, open licensed, and solo friendly. Character creation is quick, play focuses on clever problem solving, and combat is fast and deadly.

If you love Year Zero Engine, Into the Odd, MÖRK BORG and Blades in the Dark, you’ll feel right at home. 

Light on rules, bound to the dark.
