Hunter was forced to abandon life as he knew it when he first arrived on the ice world of the Pillar. But, unlike so many others, he didn't let the merciless conditions of his new home break him. Since his very first day in this joyless, freezing hellscape, he fought for survival. He can never let his guard down, because he knows that his strength and determination not only keep him alive, but also those who believe in him.

Navigating the snowy wastes, hunting massive bears for meat and furs, battling winged fiends and zombie-like Walkers that shoot electric pulses from their chests, Hunter is ever ready for new challenges. He has agreed to take part in the first expedition to the Bunker in years.

Deftly maneuvering a heavy-duty all-terrain vehicle through the snows, he and a handful of daredevils set out on a dangerous journey to investigate the underground bunker known as Captain and find out why it went silent long ago . . .
