The biggest and best adventures of Marvel's mighty mutants - these are the X-Men Milestones! Powerful anti-mutant bigots have resurrected a techno-organic alien nightmare: the Phalanx, a cold, vicious and unstoppable foe that absorbs all in its path. But these creatures are far more than their creators bargained for - and they plan to summon their parent race to overtake Earth! When the Phalanx capture the X-Men, the remaining X-teams must split into three groups - to save young mutants from the Phalanx's clutches, to prevent their foes from contacting their homeworld and to rescue the X-Men! But even with the aid of the rogue Phalanx unit Douglock, can these ragtag teams succeed?
