Ubisoft had the biggest surprise of E3 2012 in Watch Dogs, a game that plays on the anxiety of maintaining one's private identity in this digital age, and now a promo mailing for the game highlights those fears in a very real way with the release of roughly 1,000 fan email addresses. The mailing related to an ARG connected with the E3 demo's dotconnexion gallery and its owner, Joseph DeMarco, the assassination target in that demo.
The email in question, sent out by a representative of the fictional gallery, included roughly 1,000 real email address in the CC field (as opposed to the BCC field, which would have kept them hidden). The emails were sent out in waves, and the mistake appears to have been corrected after the first chunk -- email addresses starting with A and B -- based on messages that were forwarded along to Kotaku. It seems pretty clear that this was an honest mistake rather than some PR stunt, but it's also undeniably an object example of the sorts of anxieties that Watch Dogs will toy with.
Ubisoft hasn't confirmed a release date, full list of supported platforms, or anything else, but you should definitely take a peek at our Watch Dogs preview from E3 2012 for a deeper look into this slick-looking game.
