While the two games have basically been linked for a while now,
NCSoft has made it official today. Their super hero MMOs
City of Heroes and
City of Villains are now merged into one game product. People who own one of the two games can now access all of the content of the game they didn't already own and all copies of both games sold at retails stores and online will gain access to both games.
One of the more interesting features in this merge is that people who play as heroes can now have access to base building, which is something only
City of Villains players had access to until now. It also will lead into future updates and projects for
City of Heroes that will be announced later this year.
