The lineup of villains in the upcoming Arkham City can be difficult to keep track of for anyone but the biggest Batman fans. If names like Hugo Strange and Deadshot don't ring a bell with you, head over to Comic Book Resources who have created a "Who's Who" list of all the villains that we know to be appearing in the game up to this point. It's an entertaining read whether your familiarity with the character doesn't extend past the first game and the movies or if you're familiar with the Bat-Mite, and a good way to kill a Monday afternoon.
