“…for the threat of Ultron looms above them once again…”
The European country of Slorenia is dead. Every man, woman and child, eliminated with the cold precision of a machine. And out of the flaming remnants of this tine Baltic state comes a message from its murderer: Mankind’s dominance of the Earth is to be challenged and its days numbered… because ULTRON has returned.
He – or it – is one of the Avengers’ oldest, most implacable foes, manacling humanity countless times. But never before has Ultron been this dangerous, this deadly. Now, he stands on the brink of committing global genocide, and rebuilding the Earth in his own robotic image. Our only hope is a desperate U.N. strike on Slorenia, led by the Avengers themselves. But will it be in time? Will the strength and courage of Earth’s Mightiest Heroes be enough in the face of such overwhelming evil?
For the sake of the world… it will have to be.
