StormHack! exclamation edition beta
A downloadable game
This is the first beta of StormHack! (exclamation edition), an "inverted" OSR game where it's the demonic side of your PC that levels up as long as your PC chooses to lean on their supernatural boons , with accompanying problems. This should be compatible with and suitable for all kinds of "old school" sword and sorcery adventures but was specifically intended to use resources written for various RPGs based on the works of a particular British New Wave SFF author.
