DC Universe Online features three expansive City Zones that serve as the Game World for DCUO. The cities are split up into different districts or boroughs. Players that choose The Joker or Batman as their mentor will be sent to Gotham City after they complete the Brainiac Ship starting event, and Players that choose Superman, Lex Luthor, Wonder Woman or Circe will be sent to Metropolis after they complete the Brainiac Ship starting event. If you bought the lightning strikes dlc you may travel to Central City once you have a combat rating of 53. You are free to traverse between the three cities at any level.
