Duke was a member of the United States Colonial Marine Corps and part of the second Hadley's Hope detachment.
Duke was fighting Xenomorphs alongside Angie Duplis inside the Hadley's Hope Operations. When Corporal Winter arrived to rescue the surviving Marines, he was too late to save Duke, who was almost immediately killed by a Warrior. Cpl. Winter was, however, able to save A. Duplis by killing the remaining Xenomorphs.
