A new trailer hit tonight for Avengers: Age of Ultron during the football game and this one is a whole hell of a lot darker than the last. The trailer, which is comprised of almost entirely new footage gives new tidbits of the story. Am I wrong, or did they show Black Widow getting some Cybernetic implants?

When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth’s Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.
