Before presenting the latest milestone in the development of InFamous 2 at GDC today, Sucker Punch Productions development director Chris Zimmerman told his captive audience, "What we saw as the biggest problem with InFamous was that, at some point, it ended." That won't be an issue in this sequel, thanks to user-generated content.

Zimmerman says that the developer has planned to integrate user-created missions from the outset, keeping the feature secret for two years. "That's hard to do," he said with laugh.

Players will have access to "All of the good guys, all of the bad guys, all of the props that we built for the game -- vehicles, weapons and other stuff -- and then a whole bunch of special stuff we built just for making user-generated content," he confirmed. " We figured we'd throw that all out there and let people create, because we think there are lots of people out there that dream of being a game designer, and this is our opportunity to give them the opportunity to share what they can do. To take all of this content we've built over the past two years and putting it together to make something we never thought possible."
