This guide was created as an answer given to a prior expeditions to help others new to NMS Expeditions or unsure how best to transfer items to their Primary save.

It does assume you started the expedition from an existing save game, stand-alone games auto convert to a Primary game once the End Expedition button is used, no transfer is required because ending the expedition makes your game a primary save game.

Anyway, onto the guide, its basic, assumes you know where things are and can follow approximate instructions, it has worked for multiple expeditions for me and others.

If you get lost following the guide, remember this, DO NOT click the "END EXPEDITION" button until you are absolutely sure you are ready to end it.

So long as you have not ended the expedition at the anomaly using the "End Expedition" button, means you can still transfer items and technology to your Primary Save.

When you do end the expedition, everything you had becomes units and nanities, other than quicksilver that you will have been awarded/due to be awarded, so all items in storage on the expedition save is converted as above, you just get paid for them.

To transfer items to your main is a bit of a tedious task but possible as follows:

• Ensure you have completed all phases of the expedition, accepted ALL rewards AND accepted the final phase screen with the Expedition Gold and Black banner, this is a MUST to unlock the Transfer screen.
  
  
• From there you can load up your inventory with items and technology you want to transfer, 8 technology and 24 items (as of this guide) PER transfer, which you repeat as many times as needed.
  
  
• Visit the expedition console in the anomaly to transfer items and/or technology to your primary game.
  
  
• Once all slots are filled in the console use the RETURN key [see bottom right of screen] (right click if mouse/keyboard) to exit, DO NOT use the "End Expedition" button.
  
  
• TIP: I usually jump in/out of a ship to save, this has been found to be essential as exiting the console has an auto save on exit, which is... ahem, unsafe.
  
  
• Hit ESC (mouse/keyboard) and in "Options" change to "Primary Save".
  
  
• Go to the console at the anomaly and extract all your stuff, put them into cargo as needed to free up your inventory space.
  
  
• TIP: Again I jump in/out of a ship to save.
  
  
• Return to the expedition console and use the "Resume Expedition" button to switch back into the expedition and repeat until all items are transferred over
  
  
• Note: When you resume the expedition a gold popup banner goes on about the expedition is completed, close it and carry on, but it might get buggy after your 10th item/tech transfer.

If you have good multi-tool(s) and/or ship(s) you want copied to your Primary save, make sure they are the last things you have selected before switching to the "Primary Save"; even after you end the expedition, the last selected ship/multi-tool can be copied.

Multiple ships (may exclude multiple corvettes, TBD) and multi-tools can be copied (where permitted to own them in the expedition) so long as you have free ship slots and the nanites to purchase them in your primary save.

However, it takes repeat visits to the expedition and then primary game as in the above guide to transfer one at a time.

Technology transfers with both, but inventory does not, names often reset to their default and I've found having the same ship selected in your primary game will not allow duplication back if you copied that ship into the expedition at any time. Try changing ship in primary save, that might work.

For every other ship, remove tech mods, same for multi-tools, exosuit and exocrafts, transfer all you want to your primary save as the above guide before scrapping them for units, if you would prefer units.

If you had a freighter, scrap the base and recover materials, most of the time you will just get nanities, very little unit rewards for these as they are none transferable. (as of this guide).

When you finally click the "End Expedition" button and everything totals up, some other things happen:

• Freighters and frigates will be converted to units/nanites, as will ALL inventory items you have chosen to leave behind.
  
  
• Bases will be transferred to your primary save as a location you can teleport to, NO inventories/items will be transferred, only your existing primary save items will be in the inventories as is what you have acquired prior.
  
  
• Note: Not ALL items can be transferred, this can be rewards like Eggs which can be collected from the Quicksilver interface on the anomaly.

Hopefully you have managed to save all your special items, ships or multi-tools you wanted, if not, dont worry, you can easily gather items in NMS so not all is lost.

If you have completed another Expedition, Congratulations, achievement well done pilot.
