In this second dev diary for the upcoming Marvel Heroes MMO, David Brevik discusses their open-ended approach to the game's characters, story and how they include elements from the greater Marvel universe. Brian Michael Bendis is writing the story, which will be primarily told through action comics, and in terms of player diversity you'll be able to choose multiple modern and legacy costumes for each character. I'm not terribly keen on the isometric viewpoint, but hey, it's free to play and Doctor Doom has the Tesseract. Somebody has to stop him.
