Ken McKown writes: Arkham City was easily one of the best games released last year. Rocksteady has done an amazing job of creating a wonderful Batman lore over the course of two games. When they announced they would be adding to the mix with some single-player DLC, I was truly excited to jump back in. Harley Quinn’s Revenge takes place almost immediately after the events of Arkham City. For anyone who hasn’t beaten Arkham City consider this your spoiler warning. Harley is looking to get revenge on Batman, whom she still blames for Joker’s death. What ensues is a solid outing that expands the Rocksteady Batman lore.
