Darcy Benson was played by Chelah Horsdal in the film Aliens vs. Predator: Requiem.
She is a resident of Gunnison, Colorado where, in 2004, she was the victim of a Xenomorph outbreak that ultimately led to the destruction of the town.
Her son and husband were the first to die in that event though she didn't know that. When in the next night the Xenomorphs attacked the town and began to multiply, she saw Carrie Adams dead after being killed by them. After that she trustingly joined a group of survivors in order to resist in the city centre so that they could be evacuated by the military instead of going out of the city as fast as possible, as another smaller group among them planned to do.
The military, led by Colonel Stevens, however, had other plans. They instead used them as bait for the Xenomorphs and destroyed the town with a tactical nuclear weapon rather than risk the infestation spreading. She died with them.
