Captain America (A:AoU) and Black Widow

Keep the Gem from Ultron

Captain America battles Ultron Sentries atop a trailer while Black Widow follows behind on a motorcycle. Note the handholds around the trailer. These may come in handy if Captain America slips off the side of the trailer.

The initial wave of Ultron Sentries battle Captain America on top of the trailer. Reinforcements swoop in and strafe the trailer before landing to join the fight. Ultron Prime attacks after the Ultron Sentries go down.

Black Widow moves alongside the trailer to return Captain America’s shield to him. There are two more waves of Ultron Sentries to face, and two more rounds against Ultron Prime, including one where you must tap the buttons that flash over Captain America’s head to win.

After you defeat Ultron and his forces, a car flips over the semi’s cab and lands in pieces. Assemble the bricks left behind into a communication relay. Use the S.H.I.E.L.D. Access Terminal to summon help.
