"Two years after the Infinite War the once great warring nations now lie in ruins, and humanity’s hope for a brighter future is nothing but a bitter memory. A new, seemingly unstoppable enemy, supported by the zealots of The Order, now seeks to eradicate mankind: UEF, Aeon Loyalist, and Cybran alike. With their backs against the wall and staring into the abyss, the tattered remnants of Humanity’s forces must put aside old hatreds and band together as they prepare to make one last desperate stand. One last chance. An alliance forged in blood, steel and hope, they turn to face the dark."
