X-Men by Gerry Duggan Vol. 6

The X-Men's last stand! As the chaos of mutantkind's fight back against their fall at the hands of Orchis rages in FALL OF THE HOUSE OF X, other forgotten foes come out of the woodwork to take on the X-Men in their time of peril! Synch and Talon find themselves once more besieged by the High Evolutionary and his creations to reap the consequences of their last encounter - and the results will be devastating! Then Nimrod shows just why the X-Men lived in fear of its creation! The ultimate weapon of mutant extinction is ever-adapting, ever-evolving, with only one goal: death to mutantkind! But with the end nigh, Kate Pryde and Illyana Rasputin fight side by side - blades in hand! And the X-Men assemble for what might be the last battle of the heroes of Krakoa!
