Personnel unaccounted for: Non-Essential Systems Maintenance Chief Ryley Robinson

― Aurora, Blackbox Data


The Player, also known as Non-Essential Systems Maintenance Chief Ryley Robinson is the protagonist of Subnautica. He is one of the survivors, and later the sole survivor, that survived the impact of the Aurora by escaping aboard Lifepod 5

Ryley will not serve as the protagonist in Subnautica's Expansion, Subnautica Below Zero, the role of protagonist being taken instead by Robin Goodall.


He is a young-adult male human with light brown skin, dark brown eyes, and dark hair styled in a fauxhawk with dyed light turquoise streaks. He has a long face and pronounced features. By using in-game scale to measure Ryley's height, he has been found to be approximately 168cm (5'5").

Ryley has a good degree of stamina, for he is able to swim very long distances without the need of a break, and hold his breath for prolonged periods of time.


Ryley does not typically speak, but can be heard gasping for air if he stays underwater for too long, when he is jumping, or letting out shrieks of pain if he is attacked. He can be heard grunting when escaping the Aurora in Lifepod 5, and coughing when putting out the fire inside Lifepod 5 or the Cyclops.


Almost nothing is known about Ryley's life before the crash of the Aurora, however, he was a member of the Alterra Corporation, as Non-Essential Systems Maintenance Chief, and was on board the Aurora prior to the crash.


Ryley is seen boarding and launching Lifepod 5 during the descent of the Aurora. After being knocked out by a loose panel, Ryley then proceeds to put out a fire inside the lifepod using a Fire Extinguisher. Afterward, he activates his PDA, and the user is able to take full control of him. Upon exiting the Lifepod, Ryley unknowingly becomes infected with the Kharaa bacterium. 


After curing his Kharaa infection, receiving blueprints for and subsequently building an escape rocket from Alterra, and shutting down the Quarantine Enforcement Platform. Ryley finally manages to escape the planet. Upon returning to Alterra, he is informed that he will not be allowed to land until he settles his outstanding debt of 1 trillion credits. Accrued as, by Alterra law, all materials he used during his survival and escape were property of Alterra.
