Assault on Castle Von Doom

You arrive at the outskirts of Doomstadt and find a lot of Doombots on patrol. Doom leads you to a secret passage into the palace. The explosion from destroying it after you're through should draw the Doombots away from the city too. You'll need to move quickly though – you only have five minutes head start until the bombs go off.

Welcome to Castle Von Doom. You need to make it to Doom's lab quickly. You reach the throne room only to be confronted by Draxon, who plans to ruin Doom's name with his people then sweep in to take over. Doom attacks him but he escapes, and he can't save his people if he's dead.

Cap and Black Widow discuss who could be helping Draxon, while Doom uses his equipment and synthesizes a serum to prevent his deterioration, though a cure will take more time. Draxon will have control of the palace Servo-Guards so you'll need to find a less obvious way to reach the control room. Black Widow has an idea, but she needs to take a look at the battlements.

Black Widow sets up a zipline that should let you reach the control room. You need to get back to Cap and Doom and help them keep the Servo-Guards distracted. She also warns you that Doom is not back to full health yet. Keep a close eye on him.

Doom and Cap take on the Servo-Guards, but Doom is still struggling. Luckily Black Widow deactivates them before they can reach you. Doom runs ahead so you need to catch up!

You confront Draxon who threatens you to turn Doom and Cap against each other. He reveals that he isn't working with Zemo, but Black Widow attacks him before he can perform his big reveal. A Doombot steps out and reveals itself to be Ultron.
