The series is called Rōgun. In this setting, earth has been ravaged, her resources depleted. Noble warriors defend a mobile, solar-powered fortress, traveling from town to town. These rollerskating samouri stand against the Warriors of the Night and cybornetic Scroungers. This is Rōgun.
The Lightspeed Adventure Manual will be made available at DriveThru RPG later this month! Your gateway to 1970s-era sci-fi television roleplaying is almost here. The full Retrostar rulebook (which will feature a foreword by Battlestar Galactica's Richard Hatch) will be available in the first half of 2015.
