The year is 2130, the Ozone layer has disappeared completely due to pollution, driving humanity to migrate undersea and build underwater stations to avoid the intense solar radiation. You are the Captain of the Aurora, a small submarine whose main usage is scouting and delivering good from one station to another. With you is 3 members: Chris the security guard, Emma the engineering woman, and Ana the medical personnel.

You woke up and stretch your arms but not fully due to the claustrophobic metal hull. There are creaking sound from the submarine's shell and low humming noise of the engine, sounds that are too familiar that your brain has filtered them out instinctively. Next to you is Ana, who are looking over the medical cabinets to check the provision. She talks without looking at you

Ana: "I told you to go easy on the booze, Captain. We'd much prefer if the one steering the submarine is not hammered drunk every weekend."
