Around thirty days after Emergence Day, Corbin was part of the effort to defend the city of Halvo Bay from a huge Locust assault. Corbin fought the Locust in downtown Halvo Bay, and helped escort civilians across the rooftops toward higher ground. Sadly, she was killed by Locust fire during the mission. Corbin's COG Tag was later recovered by Lt. Damon Baird of Kilo Squad.
