The second trailer for Avengers: Age of Ultron just dropped via YouTube and shows a lot more of the action beats than the first trailer. A lot of emphasis on the Hulkbuster vs. Hulk fight is given in the trailer as well as a more detailed look of Ultron. There also appears to be a mysterious woman in the middle of the trailer, but her identity has yet to be revealed. We have yet to see the Vision in action or the Avengers actually fighting Ultron, but that will soon be revealed.
The trailer promises an exciting and potentially Marvel universe altering adventure for our heroes, both old and new. May 1, 2015 is the release date.
