A Shield Vs Hydra website has been launched where:
Entrants will enter into a universe where trust, suspicion and betrayal play out in a struggle to build the most indomitable organization. By registering for the Sweepstakes, entrants will be prompted to answer a series of questions where upon completion they will be assigned to either an agent of S.H.I.E.L.D. (an espionage and law-enforcement agency in the Marvel Comics Universe) or a double agent for Hydra (a world-wide subversive organization dedicated to global domination). Throughout the Sweepstakes entrants will be given missions to complete to determine if they are knowledgeable of the agency they represent. With each successful response they will earn badges for completing a mission and chances to win Weekly Prizes and entries into a Grand Prize Sweepstakes.
The contest runs August 18 though September 19th.
