This is it: Marvel's rag-tag group of sci-fi heroes vs. Ultron - in a double-sized finale! The surviving warriors face-off on the battlefield, with the fate of the entire Kree Empire - and perhaps the Earth itself - at stake! Who will fall? Who will rise to become a legend? It's an extra helping of adventure, humor, drama and eye-candy that IGN.com calls 'one of the best event books of the year.'
