As you are brawling your way through the waste of Pandora, a bandit ambushes you. Moments later, the man is cut in half. You then see a strange man in a black suit with a Zero in the top right. "Hello. I am Zer0, The best assassin on Pandora." You then realize, one wrong move, and that man will be you. "Here, you need more firepower." The man hands you a Jakobs revolver.
