Millions of miles from home, hundreds of ships descend into the stormy atmosphere of a hostile frozen world. On board, an army of resolute men and women brace for the coming assault. They are an invasion force, on an impossible mission - destroy the devastating enemy weapon garrisoned below. Corporal Scott and his battalion are in the vanguard but the human forces are no match for their brutal alien adversaries. Scott’s battalion is dead within moments. He is its lone survivor. The landing force annihilated, the battle is lost. Against overwhelming odds, Scott dares the unthinkable - cross behind enemy lines, survive the lethal landscape, evade capture by ruthless enemies, resist natural predators, face human deserters and finish the mission singlehandedly. Locked in his suit of full combat battle armor, sustained only by what he can carry, and driven by Earth’s wrath, Scott must do by himself what an entire army could not. Destroy the weapon. Return home.
