There are lines that the X-Men have sworn never to cross. But in the wake of the cataclysmic events of Messiah Complex, Cyclops sees the grim reality: some threats can never be contained, only eliminated. In secret, he forms a covert strike team — a black-ops unit that will do what the X-Men cannot. Wolverine, X-23, Warpath, and Wolfsbane are the claws in the dark, operating without mercy or hesitation. This is the birth of X-Force, a shadow team waging a hidden war where the cost is blood, the mission is absolute, and failure means extinction.
