She is one of the three Iron Bears sent to investigate the Zeta Site. She acquired the Artifact and, alongside the many Corporates evacuated the Pod 5 before Rykov destroyed it.
When Corporal Harrison disabled the security network in the tunnels connecting the POC to the Pods, he inadvertently disabled the security at the Pods themselves as well. Dunya's fiancé Dimitriwaskilled when Harrison shut off the security grid that was connecting the POC to the Pods and the Xenomorphs swarmed in and attacked. As a result, Dunya blamed Harrison for his death. By the time Rykov died, Dunya replaced him. It is unclear if Dunya was either dead or not when the Forward Observation Pods were destroyed. It was implied in the Predator campaign's ending that she survived. She along with a group of Iron Bears kidnapped some Weyland-Yutani scientists before they escaped from LV-1201.
