Uncanny X-Men (Uncanny X-Men Vol. 6 #9)

The Outliers, still finding their place in the mutant world, are hunted by a lethal new set of foes: A bloodthirsty, relentless and unstoppable pack of stealth Sentinels! Cut off from their mentors and allies, with no knowledge of who built or aimed these deadly drones, four untrained mutants are on the run and completely unprepared for the violent hunters making them their prey!
