Who are the new Sentinels? The original Sentinel program was human supremacy and fear coded into circuitry. But now their legacy falls into the hands of mutantkind! Powered by cutting-edge nanotech, this new generation of Sentinels protects a fragile peace between mutants and humans. Their first mission: Capture Omega Red! Next: Enter an enemy nation, infiltrate a maximum-security prison and escape with Sebastian Shaw! Can Lockstep bring his people home safely? Will Shaw get the better of the new Sentinels? Or does a greater shadow hang over Graymalkin Prison? Then, when a routine mission goes horribly wrong, the team must finally take on the biggest and baddest of all mutants: Magneto! But when being a Sentinel is your job - your life - is it possible to stay human? Collecting SENTINELS #1-5.
