NCsoft has launched a new feature for players of its popular PC MMO City of Heroes called Mission Architect that lets users generate custom missions and story arcs and share them. Using Mission Architect, discussed in depth recently at the Game Developers Conference, players can not only build missions using existing game assets, but they can also build their own characters and villains using the game's character creator. Mission architect also lets players write their own dialogue. Users of the monthly subscription-based MMO can publish three story arcs per account, and each arc can have up to five missions of up to twenty five individual objectives. The system also allows players to rate one another's user-submitted missions and stories, and players can earn in-game rewards for highly-rated content. Players can also get an extra slot for an additional story arc if theirs is hand-chosen by the City of Heroes dev team. "We are very excited for City of Heroes to be the first-ever MMO to offer this revolutionary new system to our players," says City of Heroes GM and EP Brian Clayton. "Within two weeks of opening the beta version of Mission Architect to our community, players published an astounding 5,000 custom stories, representing up to 25,000 user-created missions. Such a steady influx of fresh content offers the capacity for endless adventures to City of Heroes subscribers."
