Connect 5 Outposts with Cargo Links
Outposts can only be connected in pairs, so you will need six.
Open your scanner, navigate to the "Miscellaneous" category, and select "Cargo Link."
Connect three pairs of outposts, and the achievement will unlock.
This is a detailed guide to achieving one of the more complex achievements in the game, which is the construction and linking of outposts.
Before beginning, you should create a manual save to revert to in case of mistakes. This task does not require any special skills or additional research.
Each outpost only needs one Cargo Link, with no other buildings or resource trading necessary.
If the game does not show all outposts for linking, build additional outposts until all can be linked properly.
Obtain the necessary resources from “Jemison Mercantile” in New Atlantis on Planet Jemison in the System: Alpha Centauri. Rest for 48 hours in the game to allow the merchant to restock if needed.
Monitor progress under the game menu (Menu > Status > Crafting > Cargo Links Established).
