No Mans Sky, Expedition Saves Are An Advantage, Verified. Do any Expedition when they happen even if you do just a tiny bit, you get much more content. If your current main game save is mid to lower level it’s a huge advantage. The amount of extra build options will be there, when the Expedition ends it converts to a regular save and you keep most of the added stuff. It’s pretty damn amazing plus even more social. The Expedition save is more travelled so you will run into many more people out and about. Pretty much everything is better.
