One of the most pivotal events in modern Marvel history, with Norman Osborn storming the gats of Asgard with the fate of Earth in the balance! The lines have been drawn in final battle! In an epic story arc that began with Avengers Disassembled - and extended through House of M, Civil War and Secret Invasion - the greatest villains of the Marvel Universe are ready to make their final move against a target from time immortal: the hallowed halls of Asgard! But will the siege of Asgard be the last piece in Norman Osborn's insane bid to seize total control of the globe, or the proverbial bridge too far for the former Green Goblin? And will his machinations with Loki be the thing that loses the war, or wins him the world? It's a story years in the making - starring Captain America, Iron Man, Thor, Nick Fury and other greats of the Heroic Age!
