This is the 3rd part of the mission. As I had a clipping issue with the brother (in desk) and her disappearing on me once. This time I leave her outside (blocked the door with truck) so she would be there when we leave. he gets stuck again , But frees himself, thankfully and we complete the mission.

Deploy to Caimanes Echo. Then complete the 2 parts of the mission "Archangel" using only shotguns and CQC throughout all the challenge.
