In the Lusitania Mission Part 2: Capturing Captain Dakkar, the crew entered the Bermuda Triangle Time Portal along with another Federation Support Ship. The ride through the Time Portal was a rough one and the support ship didn't make it through without incident, in fact, it has crashed in the Pacific Ocean somewhere. There is one survivor who is racing to get a base built on a nearby island in order to contact the Artemis Charger and be rescued before time runs out and gets left behind in the year 1955.
This side mission occurs in Subnautica, on a separate gaming PC, at the Second Officers station. Each crew member will play for 20minutes in rotation as the mission unfolds. The captain is responsible for assigning crew members to the rotation.
