Although Activision and developer Vicarious Visions remains mum on details, both parties announced that the game loosely follows Marvel's Civil War storyline. This seven-issue series revolves around the U.S. government's passage of the Superhuman Registration Act. This act requests that superheroes register as human weapons of mass destruction. By doing so, the hero reveals his identity and is held to the same standards (and scrutiny) as police officers. While this sits well with some superheroes (most notably Iron Man), others (Captain America) staunchly refuse. This leads to a split in the hero community, resulting in friends turning on each other.
