The Nagakawa Bay Civilian Rescue mission is an optional mission in the Alpha Company Campaign. It can be done after completing the mission your team did based on whether they chose to spare or kill Dr. Tanaka. The team must make their way to Nagakawa Bay to start it. When a player approaches a house, the Civilians inside it will come out. However, in doing so, a bunch of zombies (mostly Hulks) will unburrow around the area. The team must deal with these as quickly as possible. After approaching all the houses, the team and civilians must make their way to the Delta-1 Transport Vessel in the Airlock. The team sends the civilians into the vessel to complete the mission.
