In Subnautica, the player is guided to important discoveries through story line cues. One of the earliest examples of this is the task of seeking out the other lifepods, as prompted by radio messages.
As soon as you start activating your Radio, you’ll start receiving occasional transmissions from other lifepods. Each transmission will include either the exact coordinates (resulting in a beacon being added to your Beacon Manager,) or a set of hints to help you locate the Lifepod.
The majority of the Aurora‘s Lifepods have apparently sunk to the seabed instead of floating at the surface. It’s a good idea to visit them in order of depth, as the deeper Lifepods will generally be more difficult or require more advanced equipment to reach.
