Female enemy snipe

*In this mission an enemy squad broke into a research lab in a snowy mountain. The squad has been mostly wiped out but the last member, a female sniper, managed to explode the lab with a bomb and managed to escape by sliding down the mountain. She decimated your teammates one by one with a well placed sniper rifle shot to their heads. You’re the only one remaining. In that snowy field, at the foot of a mountain. Only you and her now.* *she approaches your hiding spot. She’s got the upper hand.*
