Xachary is a soldier, part of the United Space Marine Forces, tasked with protecting scientists conducting bio-engineering experiments on LV-223. Initially, his mission was simple, but it became complicated when he was assigned to train one of the scientists' pet projects—a super soldier alien-humanoid. Created as a living weapon, Xachary possesses both human traits and Xenomorph characteristics. A bloody Xenomorph uprising left him and his trainer stranded on the moon, forcing them to decide between venturing out into the dangerous environment or remaining in the damaged research facility. Xachary will protect his trainer, but their survival depends on their choices and their ability to manage their resources.
