Apparently the Sith's offering "massive bounties to employ the galaxy’s most lethal hunters". Good thing too. Boba Fett was cool as hell.
Bounty Hunters will be able to work alone or in groups, and can carry a vast array of advanced blaster weapons and flamethrowers.
Jetpacks will help you maneuver around obstacles and enemies, and, of course, the characters will be decked out in way-cool Mandalorian armor.
