From publisher blurb: StarCluster 4 - Sweet Chariot is a self-contained StarCluster 4 role-playing game. Sweet Chariot is set on the world Chariot, where down is death and up is life, and the airships fly in between. A refugee laden colony ship - a desperate hijack attempt - landers thrown together from ceramic scrap - a thick, narcotic atmosphere - blazing, deadly heat - civilizations scattered on mountain peaks - 500 years of isolation... Sound like fun? Sweet Chariot is a single book containing everything needed to run a campaign on Chariot, and is interoperable with all StarCluster 4 products.
