In the year 2707, war rages between Earth's four giant corporations as they battle over the planet's dwindling resources. Amid heavy combat, an errant shell shatters an ancient buried seal, releasing a horrific mutant army from its eternal prison deep within the Earth to fulfill the ages-old prophesy and save mankind.

When Professor Xavier and Jean Grey disappear and the masion explodes, the X-men are left scattered. However with the rise of powerful enemies and a foreboding prophesy, they join together to battle for the future.

Before Charles Xavier and Erik Lensherr took the names Professor X and Magneto, they were two young men discovering their superhuman powers for the first time, working together in a desperate attempt to stop the Hellfire Club and a global nuclear war.
