Marvel Studios has revealed the official poster for "Avengers: Age of Ultron" via the Avengers' Twitter page. The poster features the entire core Avengers unit -- Captain America, Iron Man, Thor, Black Widow, Hawkeye and Hulk -- as well as Nick Fury and new recruits Scarlet Witch, Quicksilver and Vision. In the image, the ten heroes all try to hold their own against a swarming legion of Ultron drones and the debris kicked up by their assault.

While the returning Avengers all get featured placement and a chance to show off their mostly new uniforms, VIsion remains a mystery. Images of Vision have popped up all over the place in promotional tie-in art, but the character is obscured by sunlight in this poster.

The first "Avengers: Age of Ultron" poster dropped along with the first trailer back in late October. That teaser poster only included an Ultron-ized Avengers-style "A." "Avengers: Age of Ultron," written and directed by Joss Whedon, arrives in theaters on May 1.
