Alex Seropian -- who helped found developer Bungie in the 1990s -- has left Disney Interactive, where he was head of game development. After helping create the Halo franchise at Bungie, Seropian started his own studio, Wideload Games, which was then acquired by Disney when it hired Seropian in 2009 as a creative-development lead.
Disney has confirmed Seropian's departure and said he will be replaced by former Blizzard vice president Bill Roper, Game Informer reports. In 2003 Roper left Blizzard and founded Flagship Studios, which busted in 2008, and he was picked up by Cryptic Studios. In 2011, Roper left Cryptic to join Disney Interactive as vice president of the Marvel Franchise, which recently announced Marvel: Avengers Alliance coming to Facebook in Q1 this year.
