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.
