Play as everyone’s favorite maniacal tyrant-in-training…or at least his body double. With the Handsome Jack Doppelganger Pack, use the power of your good looks and charm to distract your enemies into submission. Or, just cut them down to size with your witty banter. Or just shoot them. That works too.
