The biggest and best adventures of Marvel's mighty mutants -these are the X-Men Milestones! A rogue government strike force, backed by powerful international forces and led by the mystery man known only as Bastion, has launched a massive strike against the X-Men. Jubilee and Professor X are already Bastion's captives, and now Operation: Zero Tolerance and its insidious new Prime Sentinels have overrun the X-Mansion and imprisoned half the X-Men -leaving Iceman to fend for himself on the streets of New York! Now, Cable and the X-Men must fight a war on many fronts -but it's a war they're losing. Can even the arrival of Marrow, Maggott and Cecilia Reyes turn the tide? Or will this be the X-Men's darkest hour?COLLECTING:GENERATION X (1994) 27, X-MEN (1991) 65-70, UNCANNY X-MEN (1981) 346, WOLVERINE (1988) 115-118, CABLE (1993) 45-47 | X-men/avengers: Onslaught Vol. 3 by Mark Waid, Paperback | Indigo Chapters
