In the near future, a strange phenomenon have started and it is causing massive dimensions to collapse. A dying Nick Fury have send back Jocasta, his robotic aid, with a message informing the player to get a group of heroes to restore the balance.
Ultron attacks the Stark tower just after you recruited Captain America, Black Window and Iron Man. While fighting, Jacosta noticed something peculiar and “off” about them. War Machine armor started to appear and was being self-controlled without anybody wearing it. An evil and hostile Vision joins in the battle claiming he was never in the side of humanity.
