Maybe you're just starting out in No Man's Sky. Or maybe you're well-versed in using inventory slots for Companion Units. You know to look for Multi-Tools and Starships with more slots than you currently have, and you have an extensive library of Companion Units.

But what if you don't have the resources you need to make more or the slots to build them in? A little rearrangement could make your equipment more effective and serve as a stealth upgrade for your inventory.

To make your equipment work even better in No Man's Sky, you have to be intentional about which Companion Units go in which slot. Companion Units placed close to the basic function they modify get a boost, indicated by a highlight around the slot. Think of it like Tetris for your Multi-Tool.

Below, you can see the same Companion Unit in two different Exosuit slots. In the first image, it's not connected to the base Life Support slot, and it looks like any normal item in any normal slot. In the second image, it it's connected to the Life Support slot, and it now has a glowing blue border, indicating the symmetry bonus.

You can also chain Companion Units together to boost several at once, like in the image below. Each continuous chain of connected units is highlighted with a different color — green for our Mining Beam, red for our Boltcaster and yellow for our Scanner.
