Angie Duplis was a member of the second Colonial Marine detachment to Hadley's Hope on LV-426. She was one of several Marines rescued by Corporal Winter during the efforts to resecure the ruined colony - in her case, Winter assisted her and Duke in fending off a Xenomorph attack in what was left of Operations. Afterwards, she helped Winter, Cruz and O'Neal in fighting the Xenomorphs in Hadley's Hope's Vehicle Bay, but stayed behind when the others left for Reid's UD-4L Cheyenne Dropship at the Drop Pad.
