A nightmare from beyond the grave. A hero plunges into it. The planet is nothing but a ruin, cities are devastated and humanity's greatest works are annihilated. Humanity is trapped and has nowhere to flee.
The Horde of locusts has begun its march and will not stop. The massacre has only just begun. The Coalition soldiers are in a pitiful state. All that remains are the sick, the wounded, and prisoners.
A prisoner named Marcus Fenix, who was left for dead, now bears the heavy responsibility of keeping the human race alive. He has only one certainty: humanity is not extinguished. Not yet.
