The Sith class has been officially shown at E3 and in this interview the Sith Warrior has been revealed and discussed by James Ohlen and Emmanuel Lusinchi – BioWare.
Darth Vader was the primary inspiration for the this character class. The Sith Warrior is a heavily armored Force user driven by darkness and rage, a frontline fighter who aggressively uses the Force to augment his destructive power. Depending on whether players develop their characters toward pure damage or toward a balanced offense and defense, a warrior can go toe-to-toe against the strongest enemy in the room or take apart a whole mob of lesser foes. The Sith Warrior’s attacks are all about uncontrollable rage and the overwhelming use of force.
