From publisher blurb: Orbital Platforms provides easy-to-use construction rules for the Hostile RPG and the Hostile setting. These rules follow a similar format to those found in Hostile’s starship construction rules. It includes a round up of platforms already found in Hostile, and adds a number of widespread protocols and operating procedures for these orbital stations. Finally, three example stations are included: a 30,000-ton high port, a 2,000-ton orbital defence station and a 2,000-ton research station.
