One of the marines, John "Reaper" Grimm, accompanies his sister, Dr. Samantha Grimm, to one of the labs within the devastated sector to retrieve data; here he learns that the dig site where their parents were accidentally killed was re-opened and ancient skeletons of a genetically enhanced race were discovered.While searching for survivors in the facility, the marines find Dr. Carmack, who is taken to a medical room for examination, but later disappears. The marines find a creature that leads them down to the facility's sewer. Marine Eric "Goat" Fantom is killed during their pursuit, along with the creature. The corpses of Goat and the creature are taken to the medical room. Marine Gregory "Duke" Schofield stays with Sam as she starts an autopsy, when they are attacked by a second creature. After trapping it, Sam continues the autopsy on the first creature, finding that its organs are human. Goat suddenly revives, and then kills himself by slamming his head against a glass window.The squad tracks a third creature down into the dig site, where it kills three more marines. Sam and Reaper try to convince Sarge that the creatures are humans from the facility, mutated by the addition of a Martian chromosome (called C24) they found and synthesized from the bones discovered, and that not all of those infected will fully transform into creatures. Regardless, Sarge orders his team to sanitize the entire facility. Sarge kills the creature in the medical lab (revealed to be a mutated Dr. Carmack) and executes one of his marines for defying his commands. Sam and the surviving marines are then flanked by the infected, partly mutated, humans. Only Sam and a wounded Reaper escape. Sam injects Reaper with the C24 serum, enhancing his abilities so that he is able to kill the infected humans and fully mutated creatures. Reaper then battles an infected Sarge and kills him. Having survived, Sam and Reaper enter the elevator to leave the facility., Question: Who do Sam and Reaper try to convince the creatures are human?
