The protagonist of this story-driven, third-person survival horror game, which is set 300 years in the future, is Jacob Lee, a victim of circumstance who is sent to Black Iron Prison, a maximum-security facility on Callisto, Jupiter's moon. The prison is overrun with chaos when inmates start to change into hideous creatures. Jacob must fight his way out of Black Iron Prison in order to survive, all the while learning the unsettling and sinister truths hidden beneath Callisto's surface. In order to outrun the growing threat and escape the horrors of Jupiter's Dead Moon, Jacob will need to modify his tactics to combat the quickly evolving creatures while scavenging to unlock new weapons, gear, and abilities. He will do this by using a unique blend of close-quarters combat and shooting.
