From the introduction:
A favored archetype of long-time Star Wars gamers, the tech specialist is a character that focuses on modifying and enhanced fantastic technology to fit his or her needs. Tech specialists range from brilliant engineers to prodigious outlaw techs, though all share a love for the guns, gear, and gadgets found in the galaxy far, far away.
This web enhancement includes a few rules (cut from the Saga Edition core rulebook for space) that allow heroes to take on the role of the tech specialist. Additionally, you will find sample heroic characters - a Zabrak engineer and a Mon Calamari outlaw tech - that illustrate two ways to build tech-oriented characters for your own campaign. Of course, these are just two examples, and a hero who wants to tinker with machines and electronics has a number of options available across many different classes.
Additionally, these rules will be featured in an upcoming sourcebook for reference at the gaming table, and will be expanded upon with more talents and rules to further enhance your game.
