The Facility created X-23 to be the ultimate killing machine, an assassin for hire that would never stop until her target was dead. And now they want more of her. But X-23's got a new target now... them. HAMMER Agent Morales is about to see a side of X-23 that only two people have ever seen...and lived to tell about it. PLUS... Wolfsbane is reunited with X-Force just as Selene's forces descend on the X-Men.
