From publisher blurb:
Brass & Steel is a hybrid live action/tabletop roleplaying game, with rules equally suited to both. It is an alternate 1905, where the mystically-fueled industrial revolution has produced amazing feats of technology and the sun never sets on the mighty British Empire. Clockwork marvels face off against against ancient sorcery. Airships cruise the skies. Lucid dreamers explore the mysteries of the subconscious and pluck secrets from the shadows of others’ imaginations. Mighty elixirs heal shattered bodies. Steam-powered prosthetics return crippled soldiers to the front lines wielding bizarre new weapons and equipment.
All of this and much, much more are possible in the world of Brass & Steel. Join us!
Version 1.5 includes errata and some rule clarifications but no major changes to rules.
