A method of casually speedrunning Subnautica that should be accessible to most players, without requiring an eidetic memory. The run is divided into 14 “Dives”, each with a particular goal. The technique makes use of the Scanner Room, which is acquired early. Cheating is avoided as much as possible; the Captain’s Quarters Code is obtained legitimately, and while I tried to avoid multiple tanks, it was necessary at one point. This shows how to do it without the Ultra Capacity Tank, though shows acquiring the relevant Blueprints for it (its Data Box and the Modification Station) for those that wish to make it, which will make things a little easier.
