The Nek'var Empire marches across the stars.

Their ruthless campaign to purge all life from the galaxy has crushed a thousand years of peace.

Deadly fires rage in cities all across the Galactic Union, a collection of peaceful civilizations who haven't known war in centuries. Their grand armies have been crushed, cities conquered. Nothing stands between a sweeping Nek'var victory but the battered remnants of a mauled fleet.

If they fall, the galaxy falls with them.

Meanwhile, Humanity is an unknown power emerging from their little speck of space when they are inexplicably attacked by a powerful alien fleet, forcing the ever squabbling nations of Sol to forge a grudging alliance in the face of annihilation.

Corporal Erik Shields finds himself far from home, embroiled in a life or death struggle on the surface of a colony world called MX-01, battling for Humanity's future against a seemingly unstoppable force.

But there is a glimmer of hope when Fleet engineers develop a miniaturized reactor core that unlocks the Power Armor program's potential, and a desperate mission is cobbled together to deploy the hastily formed Armor Corps to the colony surface in hopes of defeating the enemy invasion.

This is a tale of defiance in the face of annihilation—the soul-crushing horror of interstellar war, and the death of dreams.
