It's the fiery finale to the first story arc by Warren Ellis! San Francisco is now ground zero for an anti-mutant war game hatched some 40 years ago. The only people with a prayer of stopping it without massive loss of life are X-Force. But what they don't know is that not only are the people who originally planned it still here, but that they also intend to see their plot through to the bitter end! Finally, to X-Force's surprise, their current "mentor" Pete Wisdsom has been "dealt" with by their opponents.
