Rogue Elements is a Shadowrun 4th Edition game. It uses the Shadowrun 4th Edition ruleset in an alternate setting, that of the year 2270. Metahumanity has developed spacecraft capable of interstellar flight, and has subsequently expanded to cover roughly a fourth of the galaxy. No alien races have been discovered as of yet, but there are plenty of different people out there, just waiting to be met. Or killed. Or worked for. Take your pick. The game follows the adventures of the crew of the Silver Lining, a mercenary craft captained by one Captain Joseph Alaren and his First Mate and daughter, Elise Alaren.
