The latest free content update to NCsoft's long running super-hero MMO City of Heroes has now gone live, according to a note on the game's official message boards. As we have previously reported Issue 13, titled Power and Responsibility, adds a number of new features, including the concept of Day Jobs to the game. Basically it means that locations in the game when players log out determine their "secret identity" (log out of City Hall and your offline character becomes a city official, for example). Each job can unlock new rewards once you spent enough time at it.

Other new features include allowing two build-outs for each character, a Leveling Pack that lets you and a friend make characters and have them have the same experience points (even if your buddy plays more than you) along with new Power Sets and other new additions. Our sister site Joystiq has a quick interview with NCsoft's Matt Miller about today's update. NCsoft is also signing up folks to test out the upcoming Macintosh version of City of Heroes. The sign-up page for the beta test announces that the Mac version will have its own exclusive costume set and a Mission Teleporter that will allow players to instantly go their active mission.
