Beltstrike (2008)

From the back of the book:

"In the Sonares system the Schaeffer belt offers riches to those equipped to exploit it - the hardy men and women who ply the dangers of the asteroid fields: the Belters.

When Lothrain Free Company invests in a mining platform, in a bid to gain ground on its immediate competition and the powerful Maas Industries, it triggers a series of events that drive Schaeffer belt tensions to new highs. Everything is at stake: Lothrain's interests and reputation; the Maas stranglehold on the most profitable areas of the belt; and certain people within the Sonares system will stop at nothing to either put Lothrain out of business, or take the mining platform for themselves. The characters find themselves embroiled in secrets, intrigue and deception all the way as they attempt to recommission the platform. They will have to face piracy, the duplicity of other Free Companies, the shady world of Maas' dirty tricks department and the secrets of the Schaeffer belt itself - secrets so explosive that they could ignite war across the entire Sonares system.

Beltstrike provides everything needed for adventures set in the depths of the asteroid belt. Character creation, rules for prospecting, plus the equipment needed for a career in belting. The Beltstrike campaign then takes the characters through the unfolding events of the Schaeffer belt as Lothrain Free Company struggles to realise its position against those who would see it fail."
