Margaret Weis Productions is flexing its licensing muscles. Stepping up from properties like Leverage, Serenity, and Smallville, the company announced at Gen Con that it has secured the rights to produce a Marvel superheroes RPG. Planned to launch in 2012, Marvel Heroes will build off the Cortex Plus system and enable players to adopt the personas of famous Marvel superheroes like Spider-Man, Captain America, or Wolverine. The first product will be a Basic Game in February 2012.
