This guide will let you know how to get S Class Upgrades for your Living ship in No Man’s Sky.
There are two ways you can get upgrades for your living ship. The first way is to use psychonic eggs to get upgrades which you can get by sending out fright expeditions. When they return, they’ll have a chance to bring back a psychonic egg.
You may get the S-class upgrades from the eggs. But if you don’t get an S class upgrade, then you have to install the upgrade and then hover over it and you can use nanites to upgrade the module into an S class. It will cost a good amount of nanites.
The other way is by just randomly pulsing around in a system until you find a void egg and when you destroy the void egg, you will get an upgrade for the living ship. You will need to be flying/using a living ship to find the void egg.
