GameFront, "In a special PAX presentation, Gearbox showed a play-through of a mission from Borderlands 2. The protagonist was a Gunzerker class character. Similar to the Bezerker, he’s a big tough brawler. But when he activates his special he gets to dual wield guns instead of fists. Also shown was a new Siren character. Her special abilities are also all new, though the presenter declined to comment on them. As the Siren joined the Gunzerker, the Gearbox presenter remarked that it will be easier to join friend’s missions already in progress without having to go back and complete prerequisite quests."
